Hi, I have only requested passengers boarding with GSX and I do not know why the software did not enter the rear staircase.
I would like to clarify that for "rear staircase" I mean the one marked in yellow (see image), not the one on the tail.
I apologize if I have not been very precise, but this consideration was implicit in my question and I hope to receive your help also to solve this aspect.
Thank you.
p.s.: however, the hydraulic pressure was active and I do not know why the extension of the tail staircase does not extend completely, but this is a problem of my Maddog, not GSX.
