hooked4life Posted January 28, 2010 Report Share Posted January 28, 2010 So I'm studying for Commercial right now and one of the FAA questions I'm having trouble understanding is this: Using left pedal to assist a left turn during an autorotative descent will probably cause the rotor RPM to?and the correct answer given in the ASA test bank is: increase and the aircraft nose to pitch down. the explanation they give for this is: Use of antitorque pedals to assist or speed the turn causes loss of airspeed and downward pitching of the nose, especially when the left pedal is used. Where does the increase in RPM come in? I thought that using left pedal in an auto would DECREASE RPM...I was under the impression that you're kind of robbing inertia from the Main rotor to power the tail rotor when you use left pedal with out the engine driving the rotors. I don't really understand the whole concept and was hoping that someone could clarify what exactly is going on in this situation. Quote Link to comment Share on other sites More sharing options...
