Mach Trim
The Mach trim system is incorporated into the Integrated Avionics Processor System (IAPS) and uses
the same pitch trim servomotor as the manual electric trim and the auto electric trim systems. The Mach
trim system receives Mach number data from the air data computers and computes trim tab deflection
to increase longitudinal stability at Mach numbers above 0.75 Mach when the autopilot is not engaged.
Faults which render the system inoperative (fail passive) will result in a warning given by the MACH
TRIM FAIL annunciator coming on at the top right of the MWS panel.
The MACH TRIM FAIL annunciator is powered from the PE busbar.
NOTE: During initial airplane power up, the MACH TRIM FAIL annunciator may illuminate until the
autopilot system is engaged and disengaged. If the MACH TRIM FAIL annunciator does not
extinguish, there is a fault within the Mach Trim system.
