MANUAL ELECTRIC TRIM

Manual Electric Trim (MET) is available in aircraft that have an
NOTE:
autopilot servo connected to the pitch trim system. The same servo provides
both the MET and Autotrim functions.
When the autopilot is engaged, moving the MET Switch will
NOTE:
disengage the AP.
When the autopilot is not engaged, the pitch trim servo may be used to provide
manual electric trim (MET). This allows the aircraft to be trimmed using a control stick
switch. The MET switch is split into two adjacent parts which must be moved together
to arm and activate the trim command.

AUTOTRIM

Autotrim is available in aircraft that have an autopilot servo
NOTE:
connected to the pitch trim system. The same servo provides both the MET
and Autotrim functions.
Autotrim will automatically adjust the pitch trim to keep the aircraft trimmed while
the autopilot is engaged. Autotrim can be disabled by pressing the AP DISC / TRIM
INT or CWS button.
If pitch trim fails while the autopilot is engaged (as indicated by P TRIM FAIL
message and AP LED illuminated yellow) the pilot can continue to use the autopilot
and manually trim the aircraft in response to any mistrim messages.
