|
DESCRIBE SPEED SET CAM
|
SETS 100% RPM IN THE FLIGHT RANGE
COMPRESSES THE SPEEDER SPRING BELOW FLIGHT IDLE, SO THAT BLADE ANGLE IS CONTROLLED BY POWER LEVER POSITION. |
|
|
DESCRIBE BETA SET CAM
|
WORKS IN CONJUNCTION WITH THE BETA FOLLOW UP CAM ON THE BETA SHAFT, IT SELECTS THE BLADE ANGLE IN THE BETA RANGE AND PROVIDES BETA FOLLOW UP IN THE FLIGHT RANGE.
|
|
|
DESCRIBE FEATHER AND DISARM CAM
|
POSITIONS THE FEATHER VALVE TO FEATHER WHEN THE EMERGENCY SHUTDOWN HANDLE IS PULLED AND REPOSITIONS THE NTS LINKAGE SO AS TO NOT ACTUATE THE FEATHER VALVE BELOW 24* COORDINATOR
