And he will ask at least one, if not all three on your Helicopter Private Pilot Checkride! Hello everybody, Kenny Keller with Fort Wayne Helicopters and I wanted to give you a tip on something people get confused on their Check-rides. The Three T’s: Effective Translational Lift, Transverse Flow Effect, and Translating Tendency. This is one of the ones that I have seen in a lot of years of teaching that always gets people confused in the heat of the moment of the Check-ride. They mess these up all the time. So I am going to give you just some real quick definitions to break them down. Effective Translational Lift (ETL) is increased efficiency due to clean air coming into the Rotor System. Transverse Flow Effect, we have clean air coming in so you have more lift in the front, less lift in the back. Due to Gyroscopic Procession, during a Helicopter Takeoff, the Helicopter wants to drift to the right and so we counter act with left cyclic. The third one is Translating Tendency. It is the tendency of the Helicopter to drift to the right due to Tail-rotor Thrust. In the Enstrom particularly, the Rotor Mast is rigged slightly to the left to counteract that right hand drift. So the Three T’s, memorize these before you go to your check-ride because everybody gets three confused. So if this helps please click the like …
