Salute!
First, I gotta agree with Chris that "Barbies' friend" needs to make some noise. Just imagine if the Lion Air crew that fought MCAS for miniutes until turning off all electric trim would have crowed loudly, and soon. Even let the next crew know.
Second, I also agree with Chris that Optimistic's topic needs to be brought up every now and then, and ditto for other fundamentals of the aerodynamic characteristics of the planes that most here fly ( versus the fighters that I flew, and that others here flew before moving to the heavies).
Mostly I wish to agree with BOAC that small elevators and big stabs can easily create problems whereby you run outta pitch authority in short order. Sometimes too short. For this characteristic of a plane, I go to the designers and then the test folks to define the limits and either you never run outta authority or you can only run outta authority in exremely adverse conditions. And let us all know what those conditions are and how to avoid them.
For the newbies that did not participate in the 447 threads, if you see my vita on the profile ( one of few with actual experience and such, I might add), I only flew two planes after training that had fixed stabs and real elevators. The other four had all-moving stabs ( elevons in the Deuce) and were hydraulically actuated with zero mechanical feedback. Zero. As with the other two planes, I used the trim system, and they used electric motors and switches, not cables or pushrods. And as BOAC, Chris, JT and others here of lore, I trimmed for an attitude or AoA. And as others here have said, trimmed as needed when going around, or yanking throttle back, resulting in healthy changes in pitch moments. But I never had a huge stabilizer with many times the pitch authority of the elevator - I didn't have a steeekeeng elevator! Rant ends...
