Draft MOS Part 71 proposed an assessment of the need for provision of a Certified Air/Ground Radio Service (CA/GRS) where the total annual IFR movements at an aerodrome exceed 7,500, or where the total annual movements exceed 40,000. Current airline movement levels exceed 8,000 and therefore exceed the threshold proposed in MOS Part 71 for provision of a CA/GRS. The threshold proposed in the draft MOS Part 71 for assessment of the need for an aerodrome control service was 60,000 movements of which at least 15% are IFR or 100,000 annual movements otherwise. It is possible that the former threshold will be reached at Wagga Wagga around 2015 and the latter is certainly forecast to occur within the planning period. Forecast movements indicate that an assessment of the need for provision of an aerodrome control service will be needed during the planning period because annual movements are forecast to exceed 100,000 and the traffic mix will include airline passenger carrying operations and basic flying training. In view of recent CASA directions in relation to GAAP aerodromes, a risk assessment of operations at Wagga Wagga Airport is likely to result in a determination that a Class D Control Zone is required. This is because of the risk to passenger carrying public transport operations caused by a significant proportion of movements by basic training aeroplanes flown by inexperienced pilots. Mitigation measures would include separation of IFR public transport aircraft from other IFR flights and the provision of at least a directed traffic information service to IFR aircraft about VFR flights.
