According to Article 25 of Chapter 3 of the International Civil Aviation Flight Rules, the takeoff and landing area of a helicopter should be determined based on specific circumstances, and the diameter of the takeoff and landing site area should be determined according to the aircraft model. Its length and width shall not be less than twice the diameter of the rotor. The spacing between each takeoff and landing location should be greater than twice the diameter of the rotor, and the distance should usually be greater than four times the length of the fuselage.
1. If determined based on the size of the helicopter needed, a larger aircraft will result in a correspondingly larger apron.
2. The root site is also related. If the surrounding obstacles are good and do not affect flight, the apron can also be relatively smaller.
3. According to meteorological conditions, the main factors are wind speed and cloud height. The cloud layer cannot be very low. When a helicopter is hovering, it can see ground objects without colliding with them. Due to different aircraft models, the requirements for cloud layer height also vary. There are also requirements for wind speed, and different models also have differences.
4. Helicopter elevated helipads generally have a diameter or side length of 18-27 meters, while ground helipads have a diameter or side length of 21-60 meters.
5. When setting up an aircraft warehouse, it is necessary to connect the taxiway to the apron.
