I've noticed that when my aircraft is on the ground, especially the A-10, I see my gauges going wild. I'm just starting off the mission on the runway, the plane bounces a little so you hear a little warning at first that says "min speed".
Then I look down at the gauges, like the angle of attack and the landing indicator and it's going wild.
In the Su-27, I see something bouncing like the canopy hinge going up and down behind me. When I'm in flight, I don't see any of that, weird.
