Short instructional video by Kenny Keller explaining Loss of Tail Rotor Effectiveness (LTE) for helicopters with counterclockwise rotor rotation. Keller emphasizes memorizing the three wind directions that commonly cause LTE: (1) left/front quartering wind (catching rotor vortices and blowing them into the tail rotor), (2) wind from the left side blowing turbulence into the tail rotor, and (3) wind from behind causing weather-vaning and control oscillations. The speaker notes degrees could be memorized but prioritizes general directions.

Loss of tail rotor effectiveness guaranteed. The examiners are going to ask you a little bit about lte. One of the very important things is as far as the threes goes, is remembering the three different winds that can get you into this situation, which are left cornering from the front, coming in, catching the vortices of the rotor system, blowing them into your tail rotor, A wind off from your left hand side blowing at the tail rotor, blowing its own turbulence, its own turbulent air back into itself, or a wind behind you, causing a weather vaning effect where the tails want to go left, going right, and you're kind of going back and forth trying to control the aircraft. You need to know those three winds. And I want to mention this is for a helicopter with a counterclockwise rotating system. So those three ones again, that you need to know is quartering wind from the front, blowing back this direction towards your tail rotor, a wind directly into the tail rotor and the wind coming up from behind you. If you want to memorize the actual degrees, that would be awesome. But to me, what's really important is knowing those general wind directions that are going to get you into trouble. So thanks for stopping by as always, and we will see you in the next video.
