The 'hazard' can be the pilot and/or installation :cheezy grin:the popular 'experimental' autoilots have failsafe features, unlike some of the situations mentioned in the Safety Digest - they were referring to GA certified systems I believe. One brand that I have fitted to our plane, and installed many of, has a simple friction clutch which is engaged wih a solenoid - IF the solenoid 'locks in' (almost impossible) then you can physically move the stick to override it, what could be simpler than that:thumb_up:
