What would that procedure be Sir?? reviewed the manual and could not find the steps or procedure to follow.
There's nothing to do. If the airplane door is set correctly, the jetway will line up with it correctly. And, this is not even something that is controlled by GSX. It's done by SODE so, the only possible reason for a jetway not lining on the airplane door, is the airplane door is not set correctly in GSX.
*So the problem is the airplane configuration then, the door is not probably set to the correct height. Correct?
That's the only possible explanation.
*As you view the passengers heading out the aircraft their heights are suitable enough and would not run their heads on the way out but Yes on the way in. Therefore I think that the position height of the jetway would be a factor.....correct?
Are you using a small airplane, like a business jet ? All passengers animations weren't made taking into account the chance that on some airplanes the door would require a bit of crouching. It might be something for a future update.
