AUTOPILOT MISTRIM ANNUNCIATION
E or A
annunciation on PFDs indicates that autopilot is flying
airplane in mistrimmed condition. If mistrim indication
continues for more than a few seconds:
NOTE
If continuous mistrim indication is
presented, pilot should brace flight
controls and disconnect autopilot.
Upon disconnect, pilot will experience
a force in excess of 25 pounds. Re-en-
gagement of autopilot should not be
attempted until reason for out-of-trim
state has been isolated, corrected,
and airplane has been returned to a
trimmed condition.
Intentional or automatic stick free dis-
engagement of autopilot into annunci-
ated red elevator mistrim indication will
induce significant airplane response in
direction of mistrim force.
