Lynx Mk 7 AFCS fault
 

Hi, would anyone be able to help answer the following AFCS/ Hydraulics/ Servo problem? any help would be greatly appreciated.

During level flight and hover AC nose pitching by 5 to 7 degrees fore and aft. No AFCS caption. Pitch indicator needles lane 1 and lane 2 were giving full deflection in both position and demand. With either pitch lane 1 or 2 deselected fault remained. With full ASE disengaged fault remained. Fault halved with lane 1 or lane 2 hydraulics deselected, but reappeared with both systems reselected on.

Thanks.

Wow...Thats desperate!
First Post...and a deep military snag!?

Are there any greenies about? - Oh, Tea-bar! Should have known...

AFCS Problem
 

When I flew Lynx I have a similar problem but in roll - the ac was rolling left and right 15 degrees - it transpired the fault was a double feedback failure in roll so maybe yours is a feedback failure in pitch.
