how to make jetways move for addon aircraft

just want to know how

It should be the normal. Whenver I had addon aircraft it moved up to mine. I dont think it should matter.

Add on aircrafts that I have found do not normally have the jetway feature built in to the aircraft.cfg. In 1 thread I remember that a person figured out how to program the add on so the jetway would come. It was in an x,y,z coordinate format. Then you would just use the normal way to get the jetway (Park on the yellow line, turn off the engine, press (Ctrl-J) to get the jetway, then (Shift-E) to open the exit.)

they dont move on 747-700 but you do have a option for a push ramp to come out of jet just open door then hit key 2 ramp will come down but if you park next a gate witha jet way they dont move

That was me, and here's the thread:

Pick an aircraft similar in length and exit location as a starting point, and estimate how much shorter/longer the your add-on is than the one you're comparing, and go from there. I would load a flight with the aircraft starting at a suitable gate, so I wouldn't heve to fly every time I wanted a jetway.

When you start out, remember the aircraft hast to be positioned by where the coordinates in the aircraft.cfg say the exit is, not where it is visually. Then fiddle with the coordinates until the .cfg coodinates nad the visual position match.
