NEHC Newsletter Quiz Fall 2016 How much do you know about heliports? To take advantage of the helicopterâ€™s unique abilityto travel from point to point, and whether youâ€™re flying recreationally or professionally, heliports are critical infrastructure. Most of the answers to this quiz can be found in Advisory Circular, AC 150/5390-2C - Heliport Design. You may also want to refer to pertinent Federal Aviation Regulations (FAR) and the Aeronautical Information Manual (AIM). Have fun! 1. Which of the following statements correctly defines a heliport? A. Any landing or takeoff area intended for use by helicopters or other rotary wing type aircraft capable of vertical takeoff and landing profiles. B. An area of land, water, or structure used or intended to be used for the landing and takeoff of helicopters. C. The area of land, water, or a structure used or intended to be used for the landing and takeoff of helicopters, together with appurtenant buildings and facilities. D. A term sometimes used to describe a minimally developed site for boarding and discharging passengers or cargo. 2. A basic heliport consists of a touchdown and liftoff area (TLOF) contained within a final approach and takeoff area (FATO). Which of the following is not part of the design criteria for the TLOF? A. Design the TLOF so the minimum dimension (length, width, or diameter) is at least equal to the rotor diameter of the design helicopter. B. A square or rectangular shape provides the pilot with better alignment cues than a circular shape. C. A circular TLOF may be more recognizable as a heliport in an urban environment. D. An asphalt surface is more desirable for heliports the Portland Cement Concrete Pavement. 3. Which statement correctly describes the standards described in the heliport design guide (AC 150/5390-2C)? A. The standards in the AC are applicable to all helicopter designs and must be followed for construction of all heliports constructed after April 24, 2102. B. Use of the AC is mandatory for all projects funded with federal grant monies through the Airport Improvement Program (AIP). C. The AC provides standards for the design of heliports serving helicopters with single rotors. Apply basic concepts to facilities serving helicopters with tandem (front and rear) or dual (side by side) rotors, however many standards will not apply.
D. Federal agencies, states, or other authorities having jurisdiction over the construction of other heliports are exempt from standards described in the AC. 4. When it comes to obstructions in and around a heliport, which statement(s) are correct? A. To avoid presenting an obstruction hazard, locate the wind cone(s) outside the safety area, and so it does not penetrate the approach/departure or transitional surfaces. B. All obstructions that exceed 10â€™ feet in height are required to be painted with alternating red and wide stripes, each stripe not less than 2â€™ wide. . C. Make sure that heliport perimeter lights to do not penetrate a horizontal plane at the FATO elevation by more than 2 inches. D. The approach/departure path starts at the edge of the FATO and slopes upward at a slope of 10:1. No obstructions are permitted to penetrate this transitional surface. 5. Knowing the direction, and relative strength of the wind, is critical for safe helicopter operation. Regarding the windsock: A. No pilot of a helicopter carrying passenger at night may takeoff from, or land on, a heliport unless the pilot has determined the wind direction from an illuminated wind direction indicator. B. The wind cone should be placed so a pilot on the approach path can see it clearly when the helicopter is 500 feet (150 m) from the TLOF. C. For night operations, the wind cone must be internally lighted to ensure it is clearly visible. D. To avoid presenting an obstruction hazard, locate the wind cone(s) outside the safety area, and so it does not penetrate the approach/departure or transitional surfaces. 6. Can you identify the incorrect statement about heliport lighting? A. Use flush green lights meeting the requirements of FAA Airports Engineering Brief 87, Heliport Perimeter Light for Visual Meteorological Conditions (VMC), to define the TLOF perimeter. B. Make sure the raised lights do not penetrate a horizontal plane at the FATO elevation by more than 2 inches. C. Heliport identification beacons flash white/green/yellow at the rate of 30 to 45 flashes per minute. D. Heliport identification beacons flash white/white/green at the rate of 30 to 45 flashes per minute. 7. Part 157 of the Federal Aviation Regulations sets requirements for persons proposing to construct, activate, deactivate, or alter a heliport to give advance notice of their
intent to the FAA. Regarding the FAA’s role in this process: (identify the false statement(s)) A. The FAA will consider matters such as the effects the proposed action would have on existing or contemplated traffic patterns of neighboring airports. B. The FAA will consider matters such as the effects the proposed action would have on the existing airspace structure and projected programs of the FAA. C. The FAA will consider matters such as the effects that existing or proposed manmade objects (on file with the FAA) and natural objects within the affected area would have on the airport proposal. D. After the FAA conducts its aeronautical study the determinations are mandatory. 8. Heliports designed under the guidance of the heliport design guide are marked following specific guidelines. Which of the follow marking can you expect to see when Boston opens its new heliport? A. A TLOF marking consisting of the letter “D” followed by the dimension of the largest helicopter that the heliport will accommodate in feet. B. If a TLOF has limited weight-carrying capability, it will be marked with the maximum takeoff weight of the design helicopter, in units of thousands of pounds. C. When the pilot’s seat is over the touchdown/positioning circle (TDPC) the undercarriage will be inside the load bearing area (LBA), and all parts of the helicopter will be clear of any obstacle by a safe margin. D. A shoulder line is a marking line parallel to a helicopter parking position centerline that is intended to provide the pilot with a visual cue to assist in parking. 9. The standards in the AC are recommended for all heliports. As PPR heliports are never eligible for federal financial assistance, do not interpret any recommendation in the AC that is not required by federal law or regulation as mandatory for PPR heliports: A. True B. False 10. Which of the following requirements are required for heliports approved for instrument operations? A. B. C. D. E.
