Rudder Trim
Rudder trim is available by rotating the RUD TRIM control switch on the trim control panel (centre pedestal), in the desired direction. The control provides signals to a trim actuator that repositions the rudder neutral point.
Hydraulic power is necessary to set rudder trim. Rudder trim position is displayed on PRIMARY page, along with the allowable take-off green band.
A“CONFIG RUD TRIM”red warning message is accompanied by a “NO TAKE-OFF”aural warning. It is displayed during the take-off roll if the rudder trim is set outside the allowable take-off range.
