A/P Level Function

Messed around with the "level" A/P button on the weekend, it holds altitude but not heading, heading starts to wander a degree at a time very slowly, anyone else seeing this? (i am assuming level means "staright" and level.

Assuming the compass is calibrated try increasing the ROLL SENSITIVITY, see if that helps.

Straight and level means zero vertical speed, and zero roll angle. It does not hold an altitude or a heading. Turbulence, updrafts, or a human grabbing the controls will cause it to drift some. It does not pay any attention to the magnetic heading or track.

The point of straight and level is to recover the airplane and get it stabilized. If you have specific goals for the plane (heading, altitude), the you need to use the correct mode to achieve that.

thanks, great description. I would suggest putting that exact verbiage in the operating instruction manual for clarity. I did read the manual, but it was not clear.
