November 15, 201114 yr I have just installed the 600/700 and have had a perfect trial flight and autoland but restarting from cold and dark the Yaw damper won't stay on and the light stays on. If I click the switch it holds for a little while and then switches back and the light stays on. Engine starts fine but no matter what I do can't get Yaw damper to hold on. I don't rememebr ever having this problem before. Is it a case of RTFM.Peter Rowan

November 15, 201114 yr yh they need to be aligned before the yaw damper can be engaged Bryan Richards "People depend so much on automation that they forget how to get the automation to work." B.W.
November 15, 201114 yr I'm having some trouble with the yaw damper too time from time. What helped me was to turn the yaw damper off, then switch the FLT CONTROL B to OFF and than back to ON. After that the yaw damper will come on again. I think it is some kind of a little bug.Best regards Daniel Verhaal
