MEPT Switch
(Manual Electric
Pitch Trim)
Used to command manual electric pitch trim
An MEPT Switch is located on each control wheel.
This composite switch is split into left and right sides. The left switch is the ARM
contact and the right switch controls the DN (forward) and UP (rearward) contacts.
Pushing the MEPT ARM Switch disengages the autopilot, if currently engaged, but
does not affect yaw damper operation. The MEPT ARM Switch may be used to
acknowledge an autopilot disconnect alert and mute the associated aural tone.
Manual trim commands are generated only when both sides of the switch are operated
simultaneously. If either side of the switch is active separately for more than three
seconds, MEPT function is disabled and ‘PTRM’ (Pitch Trim Failure) is displayed as
the AFCS Status Annunciation on the PFDs. The function remains disabled until
both sides of the switch are inactivated.
