Trim Switches

The commander's trim roll l (left), r (right); the yaw trim l, r; and trim pitch up, down switches are located on panel L2. The pilot's switches are located on panel C3. The commander's trim switches on panel L2 are enabled when the trim panel on/off switch on the left side of panel F3 is positioned to on . The pilot's trim switches on panel C3 are enabled when the trim panel on/off switch on the right side of panel F3 is positioned to on. The corresponding trim RHC/panel enable/inhibit switch must be in enable in order for trimming to take place.

Each of the three trim switches on panels L2 and C3 are spring loaded to the center off position.

Redundancy management processes the two sets of switches. If two switches generate opposing commands, the resultant trim command in that axis is zero.
