25 Years IFATCA The Story of a Childhood and Youth by B. RUthy * The following article is the first of four parts that will review the history _of the first 25 years of IFATCA. It will be continued over the next 3 issues of The Controller '.

B. Ruthy Inception Although some air traffic se rvices organizations around the world can look back on many more years of tradition it is safe to say that before the second world war they basically operated a communicat ion s service providing information to pilots and receiving reports on the progress of flight to be forwarded to the operator. Pilots took decisions as to the route of flight. the levels to be fl own at etc. without referring to ground services. They main ly used these services for approach in margina l weathe r. M F direction finders were the most advanced means of assista nce from ground .

· Bernha rd Ruthy is one of the ·1athers· of IFATCA. Born in 1931 he started work first as a radi o operator in aeronautical telecommunications in the Swiss Air Nav19at1on Services (Radio-Su isse Ltd .) in 194 9 after graduating from a specia lized School for Public and Transport Services. In 1953 he became assista nt cont roller in Zurich ACC and in 195 7 obtained his li cence as TWR and APP controller at Zurich airport. In 1966 he was transferred to Radio-Suisse head· quarters where. in 19 70 he was put in cha rge of training for operational staff. In 1 gso he was promoted head. operations division of Radio-Su isse·s Air Navigation Services Branch . Sin ce 1959 he has always been active in one function or another for IFATCA and is therefore 1n an excellent position to review the first 25 years of the Federat1on·s history

ATC or Air Defence. Ferranti completes the picture.

You don't need us to tell you about Ferranti ATC systems and simulators, military and civil. Nor about Ferranti Air Defence Systems. These have been around long enough to have won an international reputation for performance, reliability and flexibility It now makes sense to combine them into a totally integrated system so that air defence and civil/military air traffic control information can be co-ordinated in conjunction with all available sensors. This Ferranti has now done, in its Airspace Management System. The advantages are obvious: efficiency and less duplication of sensors. Savings are made in display processing,

cormnunications and data handling equipment. Training is made cost effective and realistic, when you use the modular simulator and Voice Activated Management System. The software plays a vital role in everything, and here, of course, Ferranti is unequalled. Contact FerrantiI the leaders in. C3I systems expertise, and let us complete the picture.

Th e news media. even at that ea rly stage of the Federat ion. showed so me interest for the prob lems of air traffic control.

Birth Already in March 1960 the workin g group was ready to send out amended draft documents that had been discussed at the Frankfurt meeting _Th e papers were add ressed to the national associa t ions of Au stria . Belgium. Denma rk. Finland . France. Germany. Ice land. Ireland. Luxe mbourg. Netherland s. Norway. Sweden. Switzerland and the United Kingdom who had been re presented in Frankfurt. The national assoc1at1ons were 'kindly requested to state. in accord ance with the re solution of the European Meeting . their approval or any amendments to the present drafts (and digest of reas_ons). together with 20 cop ies thereof until the first of April 1 960' __ _ 1 2 of the 1 4 associations not1f1 ed the ir w illin gness to ratify the submitted draft documents by mid-1 960. Th e UK Guild of Air Traffic Control Officers and the Swedish Flyg leda re Fbrening adv ised th at they were not ready yet. Th eir approach to a European Federation was caut ious mainly becau se they did not want to beco_me invo lved in an international trade union. or rather could not do th at in accordance with their national constitution. Neverth eless the working group went ahead with prepa ri ng th e basis for the Constitutional Conference . wh ich was held in Amsterdam in October 1961 About 60 people met at the Amsterdam Centraal Hotel on October 19 I20. 1 961. for th e Const ituti ona l Conference . Th ey represe nted the 1 2 founde r members mention ed above plus all th e major c1v1 I aviation organizations at that tim e (ICAO. IATA. IFALPA. Eu rocontrol). also observers from Greece and Israe l. The confere nce was very well prepared by th e Dutc h Guild. but- as was to be expectedthere we re of course a number of last-min ute exc iteme nts. Eve rybody. however. was ve ry keen to get the whole thing going_ During the final discussion s of the papers to be accepted at th e forma l Constitutiona l Sess ion the !CAO representati ve. Mr. H.E. Pujade. rem arked that if th e Fed erat ion wanted to be hea rd and recog nized by hi s organization it had better change its name to Internation al· rather th an 'European·. For thi s reason . and due to the fact that a certa in number of controll ers· associations from outside Europe THE CONTROLLER / SEPTEMBER 1985

had already sign alled their wi ll ingness to joi n th e Fede ration in the near future . EFATCA became IFATCA in a matter of a few minutes. short ly before it was consti tut ed. To that end the fo ll owing Resolution was spon taneously and unanimously accepted: Whereas the objects. function s. and prob lems of air traffic control are of similar nature in all countries irrespective of national boundaries. and w hereas during the Constitutiona l Conference it became apparent that a number of national Associations outside Europe are interested in joining an internat io nal air traffic co ntrol federation . and whereas the foundation of a reg ional European Federation wo uld unnecessarily re strict such federation from accepting affili at ion s from outside Europe. and whereas confining the activities of the federation to a certain region cou ld unduly hamper the establishment of worldwide intern ationa l re lat ion s: now therefore the Constitutional Conference re solved to change the orig inally intended name of the federation from ·European Federation of Air Traffic Controllers· Assoc iation s· into : 'International Federation of Air Traffic Controllers' Associations' The Con stitution . Conven tion and ByLaws have bee n amended accordin gly. In th e wo rking sessions before the inaugural ceremony all basic papers prepared by the work ing group we re accepted . Th e fo ll owing representative s we re elected as Officers of the Federation: L.N . (' Tek') Tekstra (Neth erl ands) Presi dent . Hans W . Th au (Germany) Honorary Sec retary.

Th e IFATCA Headqua rt ers were to be estab li shed at Co logne / Bonn. whe re Hans Th au was working as an active control ler. Ag ain several working groups were establis hed to start work on the immediate problems. They we re to report to th e 1st Ann ual Con ference. to be held in Pari s in April 1962 .

Controllers. w hich . as its fellow organizations in other co untries. can undoubtedly do constructive work for the development of air traffic control. It is. however. in my opinion. of the highest importance. that the objective of a g uild is kept clean cut and not mixed with trade-union interests . This is the only way to really and objectively pursue the perfection of air traffic control.·

operate and what could or could not be expected of this organization. I beli eve Te k made many friends that afternoon. He said exactly what had to be said. i_ n controller's language . His speech was warmly w elcomed by all attending the in augural ceremony. Furth er speakers were Mr. Pujade for ICAO. Captain C.C. Jackson for IFALPA and Mr. J .L. Gilm ore of IATA. They all welcomed the founding of a professional organization of the air traffic controllers. conveyed their best wishes for a successful start and explained what they expected of th e Federation. W el l. after all the baby was born . After the inaugural ceremony of cou rse all attending were happy and re laxed. The proud 'fat hers' and ' m idw ifes· gathered on the steps of Vondelpark Pavil ion to have their pictures taken . before sitting dow n to an excell ent meal offered by t he City of Amsterdam . (Thi s w as the first and probably only occasion that t he majority of people attending an IFATCA Conference were united for a group picture. It would have been difficult at recent conferences to do this. ) It was. however. only after the Constitutional Conference that the work really started. Led by Te k Tekst ra the Elective Offi cers (later to become the Executive Boa rd) did an exce llent job. The ir main objective obviou sly had to be the organization of t he Federation and its work. It was only gradually that the baby learned to wa lk and produce results on the professional level. Only 6 months after the Constitutional Conference the 1st Annual Conference was convened in Paris.

Logical Step ·Aviation is since long no nati onal matter . especially not in Europe. The establishment of an intern at ional federat ion of air traffic contro ll ers· associations is therefore a logical step. if - and I would stress this again - it is the aim to enable the nationa l associations to wide n their range of vision to study jointly the problems of interest for the development of the air traffic control art and. last. but not least . to create a better understanding and good fellowship amo ng cont rollers serving international aviation.· In his ina ugural speech the newly elected Presi dent of IFATCA. Te k Tekstra. thanked all the nationa l and internati onal autho riti es/ organizat ions for their support in setting-up th e Federation. He again stressed that · 1FATCA does not intend to interfere with the national relationship emp loyer-emp loyee. wh ic h in our opinion should be left to the national trade union s. w hose prime int ere st is the soc ial we lfare of their members.· He went on to say: ' Until this moment . air traffic control ha s been a kind of " Secret Service ". The public in general . and the flying public in particular. are hardly aware of the sa fety services rendered to aviation. One of our greatest concerns is th e publicity given to our profession .

IFATCA 25 years from Member Associations


Dear Sir. Being an association of an international nature. comprising members of various European nationalities. together with military members, our applica tion for membership of IFATCA provoked some interesting discussion during the 79 70's. Th e fact that /FATCA. in spite of political and other pressures. could finally accept us as full members. constitutes a milestone not only for our own EGATS development but also for the future expansion of the international A TS society. Th e results of this recognition have indeed been mutually beneficial: our association has gained a valuable status and the federation has received some interesting contributions of EGA TS. including a considerable input of material to 'Th e Controller '. Although the Eurocontrol Guild has only been actively associated w ith /FA TCA for just over a decade. we are proud to be a par t of the International Federation which has achieved recognition by progressive governments and by our fellow professionals with in the aviation world. We look forwa rd to a continuation of this relationship in the years ahead. Jan Gordts, President Happy Anniversary!

Dear Sir. It is with great pleasure that I join my international colleagues in celebrating the 25th Anniversary of /FATCA. As one of the founding 'fathers ·. we are proud of the contribu tion that members


Th e seco nd part of the Fin al Pl enary was taken up by a Pub lic Meeting wit h Gu ests of Honour. the Rt. Hon. Hugh Fraser , MB E. M P. Secretary of State for Air Transpo rt . Unit ed Kingdom. and Air Vice-Marshal Si r Laurence Sinc lai r, Controll er NATCS. On the last day of the Conference. May 2nd , there was a choice of four visits. arranged by the confe rence sec retary: M arconi Resea rch Laboratories at Great Baddow. Essex. demonstration flights of the HARCO system in a Valetta from London Airport (Heathrow). a visit to th e Lond?n ATC faci liti es. and a visit to De Havill and s.

of our associa tion have made to its development. from such small beginnings. to the strong organization that we see today. . . A 25thAnniversary is always a time for nostalgia. and so at this time I would like to remember with special regard those members of our association who made their contribution in the early yearsMr. G. M cCudden and Mr. P.J. Flanagan who are no longer with us. Mr. P. Linehan. Mr. D. Eglinton, Mr. M . F. McCabe. Mr. J. D. Grey, Mr. J. Murphy, Mr. J. Kerin and M r. J. Power. More recently Mr. J. O 'Farrell was a Vice-President for several years . . Some of the above mentioned have by now been. elevat.e d to high office in our service and outside it which is an tndicaflon of the attraction that /FA TCA has always had for the best in our profession. At present we are also proud of the contribution being made~ IFA TCA by its Secretary and recent V1 ce- Pres1dent. Mr. P. ·


ODoherty who we hope will continue for many years to enhance the professional image of the controller by his work for I FA TCA. The last 25 years have not been all work however. th e annual conferences held in the various countries have been happy occasions for all those who attended and they have succeeded 117 spreadtng a feeling of solidarity and cam araderie among th e many natt0nalities that have participated in them Our Irish have always been well to the fo re if not in the lead in the festivities which have taken p lace after the days deliberations. I can personally remember some very pleasant times in Athens. Reyk;avik, Lyons. and of course. Dublin . I have no doubt that some of the gentlemen mentioned above can remember even happier occasions! At a time of international tension this contribution to international fellowship is probably no less important than the gatns that IFATCA has made for the working controller 117 the professt0nal technical and environmental fields Looking forward to the next 25 years I would like on behalf of the members of IATCA to wish /FA TCA well and I hope tha t it continues to attract the same level of enthusiastic commitmen t that it has in the past-and does not lose the spirit of enjoyment that has been its 'leitmotif' over the years . Best wishes. James P Lambert. President, IA TCA. THE CO NTROLLER / SEPTEMBER 1985

Mid-air! The mere mention of th e w ord itself is enough to glaze ove r th e eyes of most pilot s and se nd a shudder down the spine . Of all of aviati on' s cla ssic hobgoblin s. th e inflight co llision of tw o airc raft must surely rank at th e top . By th eir ve ry nature. mid-air co lli sion s are quite frequently fat al acc idents: In c idents of aircraft clipping or bru shing one another in flight. and then landing safely. are rare . Mid-airs generally leave one . if not both. ai rcra ft mort all y di sa bled and . oft ent1 mes. unco ntroll able . So how is it th at mid-air co lli sions occ ur w ith alarmi ng regul arity. and oft en in un con gested airspace on bri g ht. c lea r VFR days ?

Your best prot ection in V FR condit ions against a mid-air is a good pair of hi gh-visibility eyeball s.

Th e va lu e of scanning is more importa nt today th an ever before. The high degree of sop hi st ication and reli abil ity of airc raft and systems today ca n lull pilots into assuming that everythin g is A-OK in t he ir littl e realm of fli ght. It' s JUSt too ea sy to become en grossed in cockp it c hores - pun ching up a coord inate on t he RNAV or sw itc hin g t hrough rad io freq uenc ies an d to fail to keep a watchful eye on bu siness outside the airp lan e. 路1 never saw t he oth er guy' has bec ome th e c lassic . post-mi d-a ir phra se th at survivin g pilots often te ll investigators.

W hy unnecessa ril y improve your c han ces of an un expected encounter w ith anoth er aircraft?

Beca use a high percenta ge of midai rs occ ur in the vicinity of an airport. extra alertness is required in this flight phase . If you' re shooting a practice IFR appro ach inbound to an airport. be careful t hat someon e isn 't outbound on t he same course. The same cau t ion applies w hen flying over a VO R station - all t hose radia ls converge on one point. and you want to be aw are of any airplanes inbound to the same VO R at or nea r yo ur altitude. On you r approa c h to landing . use your landing light - even in broad daylight . Th e light can be an excellent aid to oth er pilot s in spotting you say. the ai rplane about to take the act ive w hen you're 100 yards from touc hdown . Al so. know th e traffic pattern th ey' ll va ry - at t he airport you're usin g. and ad here to it. The standard patt ern . of co urse. dictates entry to th e downwi nd leg at 1 .OOO feet above th e gro und and standard left turns. Some runways. however. have righthand traffic. A nd before entering the ai rport area . co m municate over the Uni com freq uency to determine the run way in use and patern information. Fl y t he t raffic pattern at prescribed alt itu des and make your turn s as squ are as yo u can. don't wander all over t he sky. Keep the pattern safe ly c lose in. so other ai rplanes don 't turn base leg wh ile you ' re out on a twomi le final approach. The pi lots of low-wing airplanes should avoid steep descents on final . because they can 't readily see beneath the airplane Conversely. pilots of high-wing airplanes shou ld try to avoid long . shallow approaches : co nverging traffic may be dropping down . unseen . from above. Be courteous - read . give way - to pilots who don 't observe sta ndard pattern practices. You ' re far better off setting up a new approach than 9

throttle-jockeying with somone anxious to get on the ground. Remember. too. that some aircraft are likely to fly faster or slower approaches than yours. so allow for these speed differences. Beyound all this. get into the habit of turning on your transponder for every flight. and make sure your transponder is in good operating condition and within safe tolerances . Consider.

too. investing in an encoding altimeter which provides controllers with your altitude. as well as your location on their radarscopes . By following these common. simple guidelines - keeping a close watch out for traffic. avoiding areas of congestion. flying standard traffic patterns. and keepi ng your radar equipment operational -you ca n help minimize the threat of mid-air col-

A Quarter Century IFATCA Some Personal Thoughts



Recent Developments in Search and Rescue

Events over the past decade in the North Sea ha ve cau sed an accelerat ion in the improvement of rescue faci lities and equipment available to civil hel ico pter operators and oil companies. Rescue equipm ent is now available wh ic h w ill vast ly enhance the recovery and surviva bility of pe ople in the sea in the event of a major inciden t offshore . The Nort h Sea . quite rightl y, is desc ri bed as th e most inhospitable op erat ing area in th e w orld . The subject of t he purc ha se of rescue or safety equ ipme nt is a high ly emoti ve one as it is hoped t ha t th e equipment w ill never be needed. The equa ti on t herefore is cost versus likel ihood of use . It is an indisputable fact th at in ind ustry. as a whole. it ta kes a di saster to g enerate change. Rescue eq uipm ent and fac ili ties are items whic h are diffi c ul t to j ustify large expendit ure on but w hi ch. if onl y used once. can pay fo r themselves many times over.

Night Rescue The aim of t his paper is to bring to the atte nt ion of the rea der the eq uipme nt that is ava il able now or in the ve ry near fut ure . Hopefully, th is w ill provoke di sc ussion and at least bring the su bject to t he fore w here it oug ht to be. Th e most sign ificant innovation in the North Sea has been t he successful introd uct ion of t he nig ht I bad wea ther rescue capab il ity of the helicopter Eve ryone has acknowledged fo r years that heli copte r rescue crews ha ve been asked to perform rescues in c ond iti ons w hich were beyond the ca pab ility of the ex isting helicopter In 1 980.

their helicopters during search-andrescue (SAR) missions . The helicopter chosen for this project was the Bell 21 2 as it was already the type being used by Bri stow s to provide an in-field search-and-rescue facility for Shell / Esso in their Brent Cormorant and Dunlin fields. The four Bell 21 2s ba sed offshore on the 'Trea sure Finder' are not solely dedicated to SAR . but are an integral part of the offshore helicopter support of these fields. For most of the time . the helicopters operate in the shuttle role . transporting workers to and from their place of w ork. With so many people employed in and around the Ea st Shetl and basin, there are bound to be accidents or illness w hich require urgent medical assistance. In 1979. an SAR facility wa s initi ated from th e support vessel the 'Treasure Finder' which helped to develo_p the quickfit capability of rescue equipment for helicopters. During the next 1 2 months there we re many innovations such as the qui c k fit capability of the Nitesun sea rc hlight. the Skyshout loudspeaker system and modified co nnections for long range auxilliary fuel tanks . which en abl ed auxilliary fuel tanks to be changed in min_utes. thu s increa sing th e range ca pab1l1ty of the heli copter . Th e obj ect of all these innovation s was to enable a helicopter in the shuttle configuration to be changed into _a full y equipped SAR helicopter w ithin 20 minutes. With experience. thi s tim e has been reduced to less th an 6 minutes . Th e next developm ent came in 1 98 0 w hen th e night / bad wea ther research and development program began. Tri als w ith th e CAA beg an in 198 1. After 2 yea rs and 230 te st fli ght hours. full CAA certifica tion o f an all weather system was gained for the Bell 2 72.

bility w hich is the most important step forw ard in S ea rc h and Rescue helicopters.

'Bristow System' No longer mu st a helicopter crew grovel around at sea level at night trying to locate a survivor in the sea. It is now po ss ible to search. locate and rescue a person in the sea without the pilot ever needing external references. Thi s Bri st ow SAR System is the most comprehensive facility in the w orld and has attracted enquiries from civilian and military organizations all over the world. In a further development for the Department of Transport o~e of ~ris­ tow' s S61 sis being fitted with a flight director coupled to an auto pilot to provide a fully automatic flight control system with an automatic hover capability . This development is under a contract with the Department of Transport to provide a dedicated 24hour all-weather helicopter to meet the Government's requirement for SAR coverage for marine and aeronautical SAR in the northern part of the North Sea and Shetland basin. CAA certification is anticipated within a few month s. Another piec e of rescue equipment which has been accepted as filling a gap in re scue capability is the EMPRA . rescue ba sket.

AIR CAT At Thomso n-CSF, we are a step ahead when it comes to designing air traffic control systems : we have been doing it for the last quarter of a century o n every continent under th e sun. At Thomson-CSF, we are a step ahead when it comes to build ing th e air traffic control syst em : we design, develop an build the complet e range of equipment ourselves, in our own factories-det ection, communications, processing and analysis of data , the same applies to our advanced software, we can call o n unprecedented industrial capacity and know-how in th e field, ou r const ant involvement in research and development has been rewarded with continuing excellence.

Nevvsbriefs Swiss Buy Cessor Monopulse SSR for Geneva A Cossor monopulse secondary surveillance radar (SSR ) system has been bought by the Swiss Civil Aviation Authorities for Geneva airport. The £250.000 contract covers the Cossor monopulse SSR system and a large vertical aperture an tenn a (CRS 512). Trials have been going on since Apri l 1984 at Geneva. which due to its topog raphy, is probably one of the most difficult radar sites in the world.

Cassar Monopulse SSR System at Claxby Cassar Elec tronics has recently c ompleted the installation of its m onopulse (Secondary Surveillance Radar) system at Claxby. one o f the sta tions in the Civil Aviation Authority 's new ra dar netw ork. The equipment comprises a Cassar 9 5 0 in terroga tor and 250 m onop ulse plot extractor. which will op era te in conjunction with a Signaal LAR primary ra dar system . The antenna is the new Cassar LVA (Large Vertical Aperture) antenna. It is seen in this picture mounted on the primary antenna. 14

Th e Swiss authorities are very satisfied w it h th e results they have bee n ach ieving since the comp lete Cassar Electronics system was insta ll ed. . Wh en the monopulse SSR was first instal led rt was operating with a li near array (hogtrough) antenna and the re were more than t he usual effects of multipath and reflections to contend wit h due to the surro un ding mountains and the building s at Geneva itself. . In September the LVA an tenna was in stalled and in th e words of the Swiss report on the trial s. 'the improvement was spectacu lar· . Init ial exam ination of recorded data showed th at processed reflections reduced from app ro ximately 1 OOO per hour to 20 per hour and ground bounced replie s. reduced from more than 10% of all replies to less than 1 .5% .. The res ults in Geneva are part icu larl y 1nterest rng because they indicate that the new generation of monopulse SSR using th e interrogator I receiver. the plot extractor and the LVA antenna together. as a comp lete system . can assist the air traffic cont roll er in marntaining f safety in difficult radar sites.

Flight number CAA ... 'means a human fate is involved

The Work of the German Air Rescue Corps by Frank M. Hein. ORF *

When there is a crac kling in the earphones and a voice requ est s clearance for flight number 'CAA .. .'. neither businessmen nor to urist groups are sitting in the ca bin behind the pilot. CAA the abbrev1at1on for ·civil Ai r Ambulance', is the International Civil Aviation Organization's (ICAO) offic ial identification code for the aircraft of the Germ an A ir Rescue Corps (O RF ) in internationa l airspace. The statutory object of th e private organization is - to put it briefly- the saving of life with the aid of aircraft. The association uses its resou rces wherever the life or health of civilians can be saved by means of rescue . transport or ambulance flights. Nothing is earned by this - the non-

profit organ ization helps without checking the financial status of the injured and irrespective of soc ial rank . nationality. race or creed . Only the fact that someone is in di stress is the deci sive factor for the takeoff of the Merlin IV C, the Learj et 3 5 A or of a rescue helicopter. If the persons involved can be tran sported an d the craft are available, then an operation is mounted . Concealed behind the matter-of-fact code on the flight plan sheets or the pilot's announ ce ment are not sc heduled fl ight s. Fli ght number 'CM .. .' mean s a human fate is involved. On boa rd eac h ambul ance aircraft are pilot and copil ot, a doctor and an experienced medical attendant. Up to 6 stretc hers and pa ti ents ca n be transported in th e Merlin - but they also fly for only one casua lty. if necessary. Inadeq uate medical ca re. lack of medicine. in suffi cient train ed medi ca l experts or excessive strain on the local fac ili ties - these are often the reasons for so~called repa triati on flight s. which consti tu te th e . bulk of foreign m1ss1ons.

Messenger is a high technology secondary radar system evolved from Marconi' s 35 years of experience in the field. Using a new design technique the wide-aperture planar antenn~ combines excellent radiation patterns and a high gain without compromising other parameters. Gap-free cover and absence of reflections have been coupled in Messenger with the high accuracy and minimum 'fruit' inherent in monopulse to provide an important new sensor for ATC. As the first stage of a 2-step approach to Mode S, Messenger involves no change to the ICAO SSR system yet can be updated to provi~e selective addressing and dat.a lmk when required. The allsohd-state inte rrogator has the high duty cycle capability which Mode S demands. Messenger's decoder/plot extractor uses advanced bit-slice processing to simplify the architecture a nd reduce the component count while extending the system's ability to disentangle garbled replies.

Dealing with unexpected problems is a much more concrete affair for the ORF pilots than for the men at headquarters. Whereas in domestic missions diffic ulties are generally limited to bad weat her and technical imponderabilities. the huma n factor becomes much more important outside Europe. The Merlin IV C and Learjet pilots have a different job from the captains of scheduled flight s ' In some southern countries . fl ying regularly develops in to an adventure.· commented one of the pilots. Whi ch is true: flight routes ha ve to be newly specified and approved by the authorit ies for each operation and technical standards vary grea tly at internationa l airports. Should the coordin ati on by the tower be inadequate. it does happen that colleagues in the cockp its of the various planes come to an arrangement amongst t hemse lves. Occasionally the on-site airline company helps out. but sometimes t here is nothing to be done w ithout spontaneous ·generosity '. w hen paying kerosene or deal ing with takeoff formalitie s. This turns the cockpit crew· s job into a race aga inst time t he patient's condition requires the greatest possible care and fast transport. It is not unusual for it to take long enough for the passengers at the point of destination to be found and taken on board If the pilots now have to wait a long time for consent. they run increasingly the risk of exceeding the maximum 19

permissible work ing period wit hout a break. It is no wonder that the crews of the ORF planes are grateful for any assitance on site. The ORF therefore exten ds a 'Th ank yo u ' to all Air Traffic Controllers and c ivil aviation officia ls worldwide whereve r they have assisted a CAA flight to be conducted safety. efficie ntly and expeditious ly.

Sir. A point which was brought to our attention as a result of an article in 'Professional Pilot · of February. is the difference of meaning of the term 'Maintain runway heading ·. 7. According to ·Professional Pilot'. the pilot maintains the heading indicated when lined up on the runway and does not make a correction to stay in the extended center line of the runway. 2. According to us. the flight instructors. the pilot takes a heading after lift off to keep the aircraft travelling on the extended center line of the runway. This difference can lead in certain situations to a conflict between two aircraft after takeoff during a crosswind situation. We would like to bring this dangerous misconception to the attention of ATC and pilots Sincerely. S . De Weerdt Secretary, Association of Belg ian Fli ght Instructors 2 7. 1985

Twenty-five Years of I LO Collaboration with IFATCA

In September-O cto ber 1960. the very year in which IFATCA was created . the Intern ational Labour Organisation held its second tripartite Ad Hoe Meeting on Civil Aviation . A request by t hat meeting fo r an I LO study on co nditions of employment and service of air na vigation services personnel led first to the publica t ion of an article entitled ' Conditions of employment in air traffi c service路 in t he September 1 963 issue of the Internatio nal Labour Review. It was w ritten by Professor J. Schen kma nn. an air t raffic co nt rol expert . on the basis of co nt ributi ons fro m several professional bodies. among which was I FATCA . Subsequent contribut ions from I FATCA we re used to present th e problem s of contro ll ers to the 19 66 Session of t he ILO Inland Transport Committ ee and ILO ' s co llaborati on w it h IFATCA received a further impet us in t he prepa rat ion of a study on Con ditions of Employment and Service of A ir Traffic Cont ro ll ers. produc ed by th e I LO w ith t he assistance of ICAO路and p ubli shed in 1 97 2 . Here aga in . IFATCA m ade a significant co ntribut ion to t he study by providing in fo rm at ion on working conditions of con troll ers in severa l coun tries . The need for a more c on crete approach to th e problems of air traffic contro ll ers was put forward by I FATCA at the I LO Preparatory M eeting for Civi l Aviation in 1974.

Thi s deci sion resulted in a period of intensive collaboration between the two organization s. as IFATCA embarked on an extensive program of collecting the comprehen sive information needed by the I LO for drafting the working document serving as a basis for the experts' disc ussions. With the assistance of IFATCA. t he ILO speci ali st w as granted access to many ATC facilities and was abl e to gather first hand inform atio n and insight on the nature of th e con troll er' s job and hi s working condi t ions.

R/T - The Vital Linl< by Geoff L. Gillett Vice-President. EGA TS

Th e Eurocontro l Guild of Air Traffic Services organized a two-day pilot I cont roll er I industry forum event on the 24 - 2 5 April. 1985 . in Heerlen Th e Netherlands . ¡ Th e theme of the forum was R / T _ Th e Vital Lin k. wh ich had as its objectives: to highlight problem areas of a tech_nical and operationa l nature in Rad io Telephony and to identify deficienc ies. particularly whe re safety might be involved to provide a platform. for the exchange of ideas and in formation on the use and abuse of R/ T in the air and_on th e ground; to provide indu stry w ith an opportunity of giving advice and information and demonstrating current and future deve lopments in air I ground and ground/ air communicat ions.

cat ions between ATC and aircrew. which have perhaps. in part. contributed to fatal accidents. Th e Eurocontrol Guild felt therefore. that it was timely to review thi s subject for its 1985 forum event . Approxim ately 1 30 persons attended the two-day forum. represen ting a w ide spectrum of the aviation industry. but the majority of representation came from th e pilots of more th an 30 airlin es both from Europe and beyond. Th e forum event comprised a series of mini-presentation s and discussion on various aspects of R/ T problem s. wh ic h had been identified by means of repli es to a questionnaire . previou sly circulated by EGATS among approximate ly 100 ai rlin e. control ler and communicatio ns industry organizations. Among th e many important conc lusion s arrived at during the event we re: many co ntroll ers do not use standard ICAO phraseo logy thereby making it sometimes difficu lt for

pilots to comprehend accurately and fully some ATC instructions clearly a potential ly dangerous situation; the rate of delivery is frequ ently too fast. An exa mple of an ATIS broadcast w as quoted where 90 wo rd s were spoken in 28 seconds ; some controllers and pilots use R/ T as a veh icle for their own ego. making witty original remarks. no doubt brought about by the boredom derived from the generally routine nature of ATC communi cations; the phenomenon of ¡selective hearing' frequently occurs (you hear only what you expect to hear); the use of more than one language on the same R/ T channel disadvantages the pilot. in that he cannot maintain a mental picture of the traffic situation in his vi cin ity. Some pi lots described this as the greatest problem in R/ T communications and would prefer the excl usive use of English for ATC purposes; information of doubtfu l value 1s often passed to pilots in situations whe re a more definite action might be appropriate. for example . wake turbu lence w arnings gi ven instead of increased spacing and the giving of unidentified traffic information at considerable range when a pilot would not be able to see such traffic. In addition. many other problems of a worldwide nature were identified and some recom mendations made: - a number of proposals for the solution of the callsign confusion problem we re discussed. including one w hich had its origins in the USA. Th is problem exists partly because co mputer limitation s dictate parameters withi n which the ATC system must funct ion; a trend which should be reversed; the problem s of stuck-on microphones causing the blocking of ATC frequencies and the dangerous situations brought about by simultaneous transm issions were examined in depth sin ce these are daily occurren ces. It was found that most company manuals appear to provide no guidance for th ese spec ific situations and the provisions in ICAO document Annex 1 0 relate more to the radio failure situations. Both pi lot and controller are therefore left to improvise to a certain extent. accord ing to the ir experi ence and the particu lar circumstances preva il ing. A possible technical solution to these problems was presented to the forum by an avionics engineer from Singapore. who gave a convincing prac -


tica l demonstrat io n in wh ic h he proved that t he device. known as t he Contran Unit (Elimin at ion of CONfl ict ing TRA Nsm issions and UN Intent ional Transmissions) could el iminate th is ongoi ng problem in ATC; the presence of a high level of ambient noise was fo und by m edi ca l experts to ha ve an adverse effect on the human dec ision-making process. although am ong hu mans w ith a higher t han average IQ leve l. noise has been foun d to increase mental performance by having a stimulating effect; t he lack of V HF comm uni cati ons fac il ities w orldwide and th e overloading of R/ T chan nels in ma ny countries still not eq ui pped w it h radar fac ilities ca me in for m uc h criticism. It is qu estionable w heth er the insta llation of pu blic telep hone facilities in some airc rah ca n be justified w hen these same aircra ft m ight st ill have no possibil ity of voice communication wit h an Air Traff ic Contro l Center; it was conc luded that in spite of t he advent of Mode S data link tec hniques. the ( Vital) Vo ice Li nk. betwee n pilot and contro ller w oul d be a continuing requ irement for t he next decade at least. It was genera lly agreed tha t both pilots an d c on t rollers co uld improve the quality of communications by stricter adheren ce to procedu res and more se lf- im posed discipl ine on R/ T channe ls. Finally. alth ou gh th ere had been c rit icism of some aspect s of R/ T communicat ion s in the USA it was acknowledged th at the European ATC system had greatl y benefi ted from the pio neer work and system deve lopment. w hi c h had its origins in th e United States and that we owed a great dea l to t he st andards defined by the FAA. It was a rare. if not unique occasion that spec ialists from airc rew. ATC and the co mmunicat ions industry co uld exchange views of commo n probl ems both in the panel sessions and during the mo re inform al soc ial moments du ri ng t hese two da ys. Now t hat many of our problem s have aga in been identifi ed. we hope that those w ho have the authority. will and understanding to bring about some highly overd ue c hanges wil l be moved to action . However. it w ill on ly be by the co ntinuing efforts of pilots and co ntrollers. both on an individ ua l basi s and through t hei r va riou s nat io nal and international organizat ions. that the searc h for an ever-improving safety re cord in aviation ca n be successful ly pursued. 24

CDA - The Efficient Approach by M . L. Burlin, A TCO at Muscat

To the five objectives of the air traffic services as defined in ICAO Annnex 11 two further objectives might perhaps be added as an updated requirement - '_to maintain a (i) quiet and (ii) economical flow of air t.raffic'. To this end the introduction of the CDA Continuous Descent Approach - has contributed greatly, as local anti-noise groups and airline operators wi ll confirm. CDA techniques are in use at a number of US , European, and other airports. three locations in Europe being Frankfurt. Gatwick. and Heathrow Airports. Currently Gatwick utilizes CDA procedures during westerly operations only, due to airspace restrict1o_ns and limitations when runway 08 1s in use. . . The CDA procedures which are design ed to permit a low-drag. lowpower descent profile. enab le an arriving aircraft to be flown in a clean configurat ion until a much later stage of the approach. thus reducing noise and fuel burn. Th e usual descent profile approximates to a three degree gl1des lope from descent points normally some short distance after stack departure In the case of Gatwick and Heathrow this is at about 23 track miles from touchdow n. Objectives Whilst the provision of the CDA is more genera ll y a feature of the busier TMA located airports. the re is no rea so n why th e system ca nnot be ut1l1zed at those terminals with lower traffic leve ls. if required on an ad-hoe ba sis. Under these circumstances the objectives of the CDA can still be achieved. The more efficient use of adjacent lower airspace can also often be permitted by rel easi ng these lower altitudes for use by other airspace users. general aviation perhaps. since the arri va ls mainta in an overa ll higher desce nt profile than under co nve ntion al approac h procedures Airspace lowe r limits ca n thus be som etimes revised upwards for examp le. Certain long-established precon ceptions ha ve to be re-exa min ed for th e introduct ion of CDA procedures . THE CON TROLLER / SE PTEMBER 19 85

in particular the accepted ILS glideslope capture from below in-level flight . Thi s is not a feature of the CDA since it obviously follows that as the requirement is to maintain a descent profile at all times. this wi ll apply both before and after establish ing on the ILS or VOR/DME radial. In areas of high traffic density the need to direct arri va ls along nominal approach paths which permit a descent equated to the required glideslope - three degrees being the normal angle - the use of pure radar separation is essential since all aircraft w ill be descending after stack departure. Thus the use of speed control is closely associated with the CDA in order to stream arriva ls and to ensure the maintenance of correct spacing w ithin the approach sequence. The choice of predetermined speeds is necessarily tailored, to suit the overa ll speed range of aircraft types operating at a particular airport. but is genera lly of the order of 21 0 knots intermed iate approach speed reducing to 1 70 knots on base leg and 1 60 knots on final approach to a four to fi ve mile fin al. after which no ATC speed restri ction may be applied. Th e intermediate approach speed is usually required to be flown within a ten knot tolerance and this does allow some limited flexibility, for example th e later variations of th e Dougl as DC9 flown by some airlines are operated at 220 knot s in preference. The majority of turbo-prop ai rlin ers and higher performance corporate aircraft can comp ly with the se speed requirements. The Concorde airc raft howeve r require s an intermed iate approach spee d of 250 knots reduc ing to 2 1 0 kn ot s 011 base leg.

Less R/T Whilst speed contro l in the co ntext of the CDA is 110 subst itute for acc urate radar vecto rin g, close attention has to be maintained to rel ative speeds and sin ce thi s may enta il frequent updating of informat ion to ATC there is a co rresponding in crease in work load. Th e i11troducti0'1 of SSR mode S offers the possibility of automatic

transmission of speed information thus redu c ing the R/ T workload The interfacing of Mode C and Mode S w ith an ATC Confl ict Alert Syste m may wel l allow the use of such a system in conjunction w ith CDA techniques in areas where presently such an Alert Fac ili ty would almost certainl y go into a continuous electronic overload . Th e advantages provi ded by the Continuous Desce nt Approach seem likely to remain of utmost importance in these times of high fuel and operating costs. together with increa sed noise awareness. Whilst the use of these techniques inevitably increa ses flight-deck and ATC workload. the overall benefits enable ATC to play an im portant part in maintaining an efficient service to the customer.

Procedural Control A New Training Facility

own EDP peopl e to meet New Zealand Air Traffic Service requirements. After co nfirming that the equipment met the spec ifi cat ion , a further four set s of equipment we re purchased. For the technically minded, a field set consists of: One SV 328 Computer, one SV 601 Expander, o ne SV 801 Flopppy Di sc Controller, one SV 902 Floppy Disc Dri ve, one ZVM-122E Amber Monitor, and an appropriate di sc .

There have always been problems with realistically simulating procedural control. In the past it has required carefully scripted exercises which often involve several people to act as 'pilots'. Further, there have been problems in realistically g iving aircraft position reports, changes in altitude and OME distances. Th is is particularly so when the controller gives instructions which may not have been anticipa ted in the script. In these days of highly sophi sticated ATC systems there are still many areas of the wo rl d whe re procedu ral. con trol is the only form of con trol avai lable. Further there are many areas whe re although radar is ava ilable, it is either used in conjunct ion with proced ural contro l or w here procedural control forms the major standby system in the even t of radar fai lure . In both the se type of areas there is a need for contro ll ers to be able to gain tra ining in procedural control, not only at ATC sc hools but also at the ir units. Up until now the main problem has been cost . New Zealand has developed a system which meet s the requirement and the cost is very sma ll .

Although we ha ve extensive radar coverage in New Zealand we still occasionally have to resort to procedural control during periods of radar failure and scheduled maintenance. Beca use these periods are rare, controllers tend to get out of practice at procedural control and trainees only get lim_ited procedural experience during rating/validation periods . Recomme ndation 1 5 of the Com mi ssion of Inquiry into Air Traffic Control Services in New Zeal and stated th at: ' Procedura l training equipment be provided at all rada r-eq uipped airports. ' In Janu ary 1983 an operational specification was comp iled and researc h showed t hat a medium-priced perso nal computer co uld do the job required . Th e hardware selected was the Spectravideo SV 328 w hich ha s 64 K of Random Access Memory.

The Pro ced ural Training Simulator is design ed to enable radar units to simulate procedural traffi c patterns at their parti c ular location s. The exercise is planned by th e user and the traffic inten sity can be va ried as required . The simulator holds data on ten aircraft types , i.e. aircraft A-J. For these aircraft the user decides the callsign, route and altitude. The simulator also allows the use r to enter data on up to six more aircraft, i.e. aircraft K-P. So if an aircraft type is required that is not in c luded in aircraft A-J then any of aircraft K-P can be used. If the type se lected is not known by the simulator then extra data on aircaft performance is fed to the machine. On ce the exercise commencement time is selected and appropriate ai rc raft programmed, the monitor disp lays th e appropri ate geographic area selected co mpl ete with reportin g points and syntheti c range-ring s, e.g . Auckland Termin al area or Wellington area. Aircra ft dat a is displayed on the right hand side of th e monitor screen in c ludin g call sign, typ e, course , ETA next reporting point, altitude , rate of c limb or descent (if any) an d range / bearing from the next re porting po int and thi s ca n be adj ust ed to give range and be aring from any repo rtin g point in the area c hose n .

The clock can be stopped / started. be slowed down or speeded up and the exercise time can be advanced if required . After an operating manu al w as compiled. the simulators were all ocated to our radar units and th is was comp leted in July 1984 . The uni ts were instructed to use the equi pm ent as much as possible and thus uncove r any bugs left in the system an d this is being achieved. It is not perfect yet. but as bugs are detected new_discs with the faults rectified will be issued to field units. Experience to date has sh own that : a) a 'driver' can be rea sona bly proficient aft er about 30 minutes dual instruction ; and b) w ith practic e a drive r can handle five or maybe six aircraft. The system is being fu rt her developed to facil itate the use of Standard Instrument Departures. It 1s also apparent th at becau se on e driver ca.n only be expected to ·pilot' five or si x aircraft at any one time. a seco nd set of equipment w ill be requ ired at each field unit to allow rea listic busy periods to be si mulated . All owing fo r t hese extra costs th e full y completed system will have cost Jess th an NZ $ 5000 fo r each set of . equi pm ent . It is felt that th is system will have w ide application in many parts of the world and be well wi thin th e means of the less affluent employers.

The International Federation of Air Traffic Controllers' Associations

IFATCA was fo unded in 1961 by Air Traffic Controllers from 1 2 European Countries: Austria, Belgium. Denmark. France. Finland. Federal Republi c of Germany, Icel and, Ireland, Lu xe mbourg, Th e Netherlands. Norway and Switzerland It has sinc e grown to over 60 Member Associat ions from all co ntinents. and is the internatio nall y recognized vo ice of t he Air Traffic Control ler. The aims and objectives of t he Federation we re formulated in Am sterdam in 196 1 and have remain ed as the foundation of I FATCA ever since . The International Federation of Air Traffic Controllers ' Associations is an independent non-government. non political professional organization. and its main objectives are: To promote safety. effi c iency and regularity in Internat ional A ir Navigat ion ; To assist and advise in the development of sa fe and orderly systems of A ir Traffic Control; To promote and uphold a high sta ndard of knowledge and professional efficiency among Air Traffic Controllers: To protect and safeg uard t he interests of t he Air Traffic Control Profession: To make mutual benefit affili ations wit h other internationa l Orga ni zat ions: To strive for a worldw ide Federati on of Air Traffic Control lers· Associations. In order to ach ieve and fo ll ow these aims. t he Federation wi ll c losely cooperate w ith nationa l and international aviation authorities. and other institut ion s or persons concerned with air navigat ion. Th e Federation sha ll assist w hereve r possible in the developmen t of new proced ures and facilities necessa ry and useful for the safety of Internat ional Air Traffi c.

Standing Committees The Federation has found t hat over the years since foundation many and co mpl ex problems and points of discussion arose and in order to provide detailed information for the Executive Boa rd and the Member Associ ations. Standing Commi tt ees we re est ablished. The Standin g Committees are drawn from the Member Associations. Eac h Standing Committee has a ch airman appoi nted by the constituent member assoc iat ion s who liaises with the Exec ut ive Board on beha lf of th e Committee. Eac h Standi ng Committee holds two or more meetings eac h yea r and m uc h of t heir work is al so done by co rresponden ce. Each Vi ce- President of t he Federation . and th e Treasurer have a direct invo lvement wit h the relevant Standing Committ ees .

penalty in operat iona l payload norma lly preclude the ca rri ag e of th e con ventional underslung load hook on most helicopters . It was therefore necessary to design a system whic h w as lightweight. simple and yet w ith th e requiremen t of being able to be jettisoned in t he event of an em ergency wit h the helicopter. The major disadvantage of conventiona l underslung load hooks is t hat they have a mechanical re lease in addition to an electrical release . It is this mechanica l rele ase w hich can open causing the prem ature re lease of th e load. Obvio usl y, this is tota lly unacceptable if we wa nt to consi der lifting people . The question was then asked - w hy do we ha ve to have a hook on the helicopter equipment? Why not put th e hook on the load? Whenever an underslung load is connected to the helicopter it requi res a person on the ground to open th e hook on the helico pter to in sert the lifting eye of the strops connected to t he load. By revers ing the conn ection. that is by having the hook on the load . the requirem ent for manual relea se in the helicopte r is unnecessary.

Another aid to safety on the North Sea being introduced is the automat ic flight monitoring or flight following fa ci lity. One such system soon to be installed offshore and in helicopte rs is Flite-Trak . This equipment enables an offshore traffic control ler to monitor helicopter and vesse l positions on a visual display unit (VDU) . A sm all transcei ver in the helicopter or on board a vessel transmits a coded si gnal to the ground station which contains. for helicopters. the callsign. position and height and for vesse ls. the vessel's identificat ion and positi on in latitude and longitude. This produces a return on the VDU sc reen alongside w hich is the airc raft identification and height. or the vesse l's identificat ion and position. In an emergency. the return on the sc reen pul sates and an audio warning is produced. It is therefore possible to highlight the particular ai rcraft or vessel in trouble. All other aircraft or surface vesse ls in the area fitted w ith the equipment. can then be vec tored to the di stre ss

airc raft in a fraction of the tim e at present possible and th e vectoring operation monitored by the contro ll er. There are many other facilities available with this equipment such as a computerized D / R fac ili ty. insta nt recall of last positions. position s of nearest land ing point s to the aircraft and many more. Th e in-flight tracking of helicopters will greatly assist area controllers in the safe routing of heli copters in addition to the increased knowledge of the position of helicopters in distress. It will be a major step forward in SAR as there will be a major t im e saving wi th the ability to vector assistance directly to the scene . As can be seen . new equipment to improve safety and search and rescue is available now. Let us hope that the advantages to be gained from thi s equipment are not held bac k until a disaster occurs. It is up to everyone to decide th at alth ough there is a cost involved . it should be paid before the ultimate price is paid .

EM P RA Basket By using the new load strop a much simpler. li ghter (weig hs less th an 10 lb) and safer system is ava il able wh ic h is perfect fo r use wi th the EM PRA A s it is so light. it can be carried on hel icopters at all times wi thout any operational payload pena lty. If the load strop was fitted to al l helicopters fl yin g offshore. any one of them wou ld be capab le of lift ing the EMPRA basket and going to t he assistance of persons in the sea . The EMPRA is also desig ned to be used by ships' c ranes or boom mast s. In heavy seas it is ve ry difficu lt to recover people from t he sea by I1fel ines from a vesse l .

SATCAS Simula tor I Controller under training

To simulate ATC you must know ATC The SATCAS simulator is an advanced air traffic c ontrol simulator, used for training of Air Traffic Controllers in both basic and advanced techniques of the approach, terminal area or en-route phase. The simulator uses the same basic equipment and modules as the SATCAS operational system. The simulator may therefore be either completely autonomous unit, or integrated in an operational system.
