Question

What flight control adjustments are critical when responding to a loss of tail rotor effectiveness?

Accepted Answer

When responding to a loss of tail rotor effectiveness (LTE), the critical flight control adjustments are: immediate reduction of collective pitch, application of cyclic pitch in the direction of the turn, and adjustment of throttle (if possible) to reduce torque. Reducing collective pitch is the most immediate and crucial action, as it reduces the amount of torque the main rotor is producing, thereby lessening the demand on the tail rotor (or whatever system is providing anti-torque). Applying cyclic pitch in the direction of the undesired turn can help to counteract the rotation. Finally, if the helicopter has a manual throttle, reducing the throttle setting can also help to reduce engine torque and the demand on the tail rotor system. The pilot must act quickly and smoothly to avoid exacerbating the situation. Recovery from LTE requires a coordinated application of these control inputs.
