Ahhh. It only happens on the RR model for me! On checking in the C:\Users\<username>\AppData\Roaming\Virtuali\Airplanes\CS_B757-200-III_RB535C, there is a gsx.cfg file there. In fact, the CS_B757-200-III_RB535C is the only aircraft listed, even though I have tried different RR versions. If I use a different RR version, the alignment of the stairs is even worse. :( Anyway. To fix this problem, you're going to have to do the alignment yourself, unless someone has already done that, and is willing to share their gsx.cfg files.

Please read this whole post.

I posted my RR gsx entry. Are you using the one I posted?
I know that my gsx cfg file works in fsx.

If you're using mine make sure the folder gsx.cfg is in matches the folder name in the simobjects/airplanes folder. You can check this very quickly. Load the aircraft in question and open the gsx aircraft editor. At the top it'll say one of three things. I dont remember the exact wording but you can figure it out.
1, using data from aircraft.cfg(you do not want this)
2, using gsx internal data(fsdt made this and could possibly be bugged)
3, using data from %appdata%(I dont remember the exact path)

The first one will ALWAYS be broken. that one won't have the door codes or proper alignment.
The second one was made by fsdt and they could have made a mistake. You can override it by making your own or placing a gsx.cfg file in the correct folder.
The third is a user created one.

Keep in mind that internal gsx aircraft data are not kept in the appdata folder. They're probably stored elsewhere or are embedded in the actual program.

You can create the folders in the appdata gsx folder. But they HAVE to match the simobjects/airplanes folder.

Each aircraft has to have its own entry. Mark, the reason that the others are worse is because they are most definitely using aircraft.cfg data. Every single aircraft has to have it's own gsx.cfg. some are handled internally. but the ones that are not will have to have it's own file. Luckily all of the 757s share the door placement and door codes. The 4d will have an extra entry but it too is shared among the other 4d. So you only need to do it twice. Then just create the folder in the appdata folder and copy the gsx.cfg folder from one a paste it into it's own folder. Again the folder HAS to match the simobjects/airplanes folder. The reason the PW works is because its supported internally. The RR is not.



As for the question about apu and engine start.  Make sure theres air going to the apu. Also make sure that the needle is around 40. You can turn the packs off temporarily. if there's not enough air the engines wont start. Regarding the apu, the apu uses fuel. I'm pretty sure the fuel it uses is from the left and right tanks. If theres no fuel the apu wont start. Also I've noticed that if you change fuel amount while the apu is running it will cut off. Simply set the apu switch to off then start it again and it will work. The apu has no time limit. I've left it running on a 6 hour flight before. It will stay running until you turn it off or all the fuel is used.
