h. Lighting. See paragraph 210. 208. HELICOPTER PARKING. If more than one

helicopter at a time is expected at a heliport, the facility should have an area designated for parking helicopters. The size of this area should depend on the number and size of helicopters to be accommodated. Parking positions should be `designed to accommodate the full range of helicopter size and weights expected at the facility. Parking positions should support the static loads of the helicopter intended to use the parking area Paragraph 806a. Parking areas may be designed as one large, paved apron or as individual, paved parking positions.

a. Location. Aircraft parking areas should not

lie under an approach departure surface. However, aircraft parking areas may lie under the transitional surfaces. 1 The parking position should be located to provide adequate clearance from any object or building. The clearance from the tail rotor arc for hover taxi operations should be 13 of the rotor diameter, but not less than 10 ft 3 m, and 10 ft 3 m for ground taxi operations. See Figure 2-17. 2 The nearest edge of a parking position should be located a minimum of 13 of the rotor diameter, from the edge of the taxi route for ‘turn- around’ and ‘taxi-through’ parking positions and a minimum of 12 rotor diameter from the edge of the taxi route for ‘back-out’ parking positions.

b. Size. Parking position sizes are dependent

upon the helicopter size. The clearance between parking positions are dependent upon the type of taxi operations ground taxi or hover taxi and the intended paths for maneuvering in and out of the parking position. 1 If all parking positions are the same size, they should be large enough to accommodate the largest helicopter that will park at the heliport. 2 When there is more than one parking position, the facility may be designed with parking positions of various sizes with at least one position that will accommodate the largest helicopter that will park at the heliport. Other parking positions may be smaller, designed for the size of the individual or range of individual helicopters planned to be parked at that position. 3 The parking position should be marked with rotor diameter of the largest helicopter that the parking position is designed to accommodate [see paragraph 208c2]. 4 “Turn-around” parking positions should be designed as illustrated in Figure 2-14 and 2-17. Figure 2-17 also provides guidance on issues other that the separation between parking positions. 5 “Taxi-through” parking positions should be designed as illustrated in Figure 2-15. When this design is used for parking positions, the heliport owner and operator should take steps to ensure that all pilots are informed that “turn-around” or “back-up” departures from the parking position are not permitted. 6 “Back-out” parking positions should be designed as illustrated in Figures 2-16 and 2-17. When this design is used for parking positions, the adjacent taxiway should be designed to accommodate hover taxi operations so that the width of the taxiway will be adequate to support “back-out” operations. NOTE: Heliport parking areas should be designed so that helicopters will be parked in an orientation that keeps the “avoid areas” around the tail rotors see Figure 2-29 clear of passenger walkways.
