So you are saying that if you AoA sensor goes bananas right after takeoff (and you have not bought the “option” to see AoA vane displayed), then as mcas activates, you start fighting it - and as you have no time to reduce thrust you develop speed of 380kts while 2000f AGL, mcas will happily apply 2.5 degrees, because you are, after all, at low mach speed?
Or... your flaps got stuck so you are landing with flaps 0, you are on short final, hit a bird directly into AoA, mcas repeatedly applies 2.5 degrees trim while you are a few hundred feet AGL, because clearly that is safe at low mach numbers?
What could possibly go wrong?
