Aileron Trim
Dual AILERON trim switches, located on the aft electronic panel, must be pushed
simultaneously to command trim changes. The trim electrically repositions the
aileron feel and centering unit, which causes the control wheel to rotate and
redefines the aileron neutral position. The amount of aileron trim is indicated on
a scale on the top of each control column.
If aileron trim is used with the autopilot engaged, the trim is not reflected in the
control wheel position. The autopilot overpowers the trim and holds the control
wheel where it is required for heading/track control.
Any aileron trim applied when the autopilot is engaged can result in an out of trim
condition and an abrupt rolling movement when the autopilot is disconnected.
