PMDG 777 Aircraft System Malfunction when use GSX Pushback Tug
« on: September 21, 2025, 01:04:40 pm »
When I perform a pushback with the PMDG 77W, I receive a message saying 'Aircraft System Malfunction: Landing Gear Malfunction' after setting the parking brake (see screenshot). I have disabled all three damage options in the MSFS 2024 menu. Does anyone have a solution?

Please clarify if this happens only with the Towbarless tug that raises the airplane, or also the one with the Towbar.

Originally, it wasn't me who posted the problem. But yes, in my sim, it only happens when I'm towed by a pushback tug that raises the airplane. A340 and A330 (both inibuilds) are affected in my case.

This happens in my sim too (MSFS 2024) with the Justflight RJ85. Both tug with bar and raising the nosewheel will result in a system malfunction with wheels. After that, taxiing can only be done with 80% engine power setting. Needless to say that I stopped using the GSX push back functionality with MSFS 2024.

There is a reason why the airplane configuration page has a "Raise airplane" checkmark, because this option can possibly have issues on some models (it depends on the airplane contact points) so if you find an airplane that doesn't react well to being raised, the option is there to be disabled.

This seems to be a completely different issue, because if it happens with both raising/non raising tugs and the issue with taxi power, seems to indicate the airplane might possibly doing something in reaction to GSX, or perhaps you have something like FsRealistic interfering ? If yes, turn off FsRealistic "Ambient Wind" function, because it's known to interfere with GSX Pushback.
