Rotor Brake Actuation
Apply brake below 40% RRPM with light to moderate pressure. Set brake handle fully forward after rotors have come to a complete stop if rotors are to be locked. Rotor brake applications below 35% should not be rapid.
Rotor Brake Application - Alternate Procedure
May be used if ground bounce (padding) is experienced.
ECLs... STOP ROTOR BRAKE lever... ARM APPLY... brake at 70% RRPM RELEASE... at 60% RRPM RRPM at 25%... apply brake again until rotors stop.
following use of rotor brake, a minimum interval of 15 minutes must be allowed before subsequent application
