Low Rotor RPM warning systems
Good day to all you helicopter Pilots. I have had a question put by the CAA regarding a helicopter that I am trying to restore to flight.
Did/do the twin turbine helicopters that you fly/flew have a Main Rotor LOW RPM warning system? Or high come to that?
I seem to remember that the Bell 212 and the S-58T has, and this must be because it has Manual Fuel control of the engines on the Twin-Pac power plant. Does the 412 have this? How about all the types.
