hi MLS i hope this helps
The mach trimmer is a system that artificially corrects for tuck above the a/c's mcrit by sensing the speed of the a/c and signaling a proportional upward movement of the elevator or variable incidence stabilizor to maintain the a/c's pitch attitude throughout it's speed range up to its max Mach demonstrated diving speed (MDF).
Good luck with the 2nd interveiw
