Wouldn't this seem to indicate that we need a warning for all control surfaces?
I'm pretty sure if I went full yoke deflection, forward and aft at high speed, I'd get some bad results. Common sense, general airmanship and a desire for self-preservation has kept me from doing that up to now. I've approached use of the rudder that way too, but who knows. Maybe I've just been lucky and any day now I may just start using full control deflections in all axes to fly the jet.
I say put on the warning lights and the more the better - maybe we're all just a bunch of idiots who need to be saved from ourselves. The FAA alway knows best.
