While waiting for the 'insight' from Fizz......................
1) Nothing really wrong with a stall warning 'going off' in a landing - if you land a C150 PROPERLY the stall warning should 'bleep' just as you touch. I agree it is not a nice thing to have on a commercial jet, however, it might frighten the pax.
2) Cannot agree with that para -THS is not 'dropped' with loss of A/P. It runs throughout the 'normal' flight regime in AB330 ie it does not 'fail',. A/P or manual. It is not there to maintain 'altitude' but to trim the tail to relieve elevator displacement (ideally!) to allow full elevator authority, just like any other trimmable tailplane.
