So for the Crj-900 and Q-400, the pushback doesn’t work correctly. I checked that the Parking brake was off, and the nose wheel steering was on. The pushback tug would push the nose wheel up, not backward, it would make the plane tailstrike. And a few seconds after, the “your plane has crashed” message would pop up.
Jet-Pack (IPACS) please fix this issue, I was wrong about the nose wheel steering, but I’m not wrong about this.
And if someone knows if it’s possible to show videos on mobile, I will gladly do so.
