Many years ago, I ruefully admit, I flew a Bonanza from HPN to RDG with a somewhat similar control-lock system still locked. (My only excuse is that there were two of us, both pilots, and we hurriedly shared the preflighting. Both of us missed the control lock.). Obviously the Bonanza didn’t have a stick, so maybe the lock only affected the rudder pedals; I don’t remember. In any case, there was enough flexibility in the system that I was perfectly able to taxi and fly the airplane. It was my first time flying a Bonanza, so perhaps an experienced Bonanza pilot would have recognized stiffness in rudder operation; I didn’t.
My only point in relating this embarrassing story is that maybe we shouldn’t assume that a control lock of this sort prevents taxiing. It sure didn’t in my case.
