I'm not sure bottom of the green would overcome a left pedal on the stops.
Green Lines, Green Arcs....are for Normal Operations.
What part of a tail rotor malfunction falls under that category?
Huey's fly at 5800 RPM with your Collective up under your arm and a built in right turn during takeoff....instead of the normal 6600 RPM (Engine RPM).
Why would you stop at the bottom of the Green Normal Operations limit if you needed to reduce the Tail Rotor Thrust in order to make a somewhat normal approach to a low hover landing?
The method works on any helicopter where the pilot can control the Nr either by hand throttle or Power lever.
