Aircraft radii

The "radius" parameter is used internally by FlightGear's AI Traffic 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:

Correct radii for future use

Please do not use these as of yet, we will likely convert all of the radii at once.

• Aircraft have often different wingspan than length. Both are important measurements to take into consideration when assigning parking spots. Most important seems to be wingspan, as that's where "hits" are most noticeable.
