Aircraft radii

The "radius" parameter is used internally by FlightGear's AI system to determine whether an AI aircraft will fit at a parking location. The rule is that aircraft will prefer to park at the smallest possible parkings, but only at those that have a radius value (in metres) that is slightly larger than the radius value of the aircraft itself. Below is the official list of aircraft radii used by FlightGear's AI system:

Airbus Airbus A320: 19 Airbus A330-200: 30 Airbus A340-300: 32 Airbus A340-500: 34 Airbus A340-600: 38 Airbus A380: 40 ATR ATR 42: 12 Beechcraft B1900D: 9 Boeing Boeing 737-300: 19 Boeing 747-400: 36 Boeing 757-200: 24 Boeing 767: 27 Boeing 777: 32 Boeing 787: 30 British Aerospace BAe 146-200: 25 Bombardier Bombardier Challenger CL-604: 11
