Challenger Lite horizon stability issue

Post by Simpsonstu »

Hi our Challenger Lite from the moment its switched on rolls left and right , wanders around in pitch and doesn't really settle down, while sat on the ground, same in the air. This is even with the engine off but its worse with it running. The other Efis onboard- Uvionix is completely stationary as it should be.

Any ideas why its so bad, do we need an SP-6, not sure what is going on?

Cheers Stu
