Understanding, Avoiding and Recovering from Loss of Tail Rotor Effectiveness
To be a good helicopter pilot and to avoid accidents, you need to know the hazardous flight conditions well.
In this other video in the series of "Hazardous Helicopter Flight Conditions", ESPN-R member Caroline Schiel, Helicopter Pilot and Flight Instructor CPL(H) FI, addresses Loss of Tail Rotor Effectiveness (LTE), also called Unanticipated Yaw (UY).
LTE results in an uncontrollable yawing motion, which can lead to a loss of helicopter control and a possible LoC-I accident.
It is induced by wind, not by a technical failure or maintenance error.
- To prevent LTE, always know where the wind is coming from, be very reactive and rigourous on the pedals, stay within the helicopter performance limitations and be very attentive during flights requiring sighificant power.
- And to recover from LTE, quickly push the opposite pedal firmly and completely.
