Hi,
In order to get your jetway working for an AI aircraft, you have to add some entries in the aircraft.cfg:
For instance:
[exits]
number_of_exits = 3
exit.0 = 0.5, -30.30, -9.0, 0.88, 0
exit.1 = 0.5, -146.0, 8.0, -7.5, 1
exit.2 = 0.5, -42.30, 9.0, -7, 2
Where exit.0 is the main exit, 1 is the cargo exit and 2 is the emergency exit (provided of course that your AI aircraft does have that many exits), where after the = you find the speed with which your door opens or closes and the postion of the door (lon,lat,vert in ft from the reference datum) and finally the type as mentioned earlier (0,1.2).
This is also true for your pilotable aircraft because FS has to know where the jetway has to go when you call it by choosing ctrl+J.
