CS 27.1143  Engine controls

ED Decision 2003/15/RM

(a)     There must be a separate power control for each engine.

(b)     Power controls must be grouped and arranged to allow:

(1)     Separate control of each engine; and

(2)     Simultaneous control of all engines.

(c)      Each power control must provide a positive and immediately responsive means of controlling its engine.

(d)     If a power control incorporates a fuel shut-off feature, the control must have a means to prevent the inadvertent movement of the control into the shut-off position. The means must:

(1)     Have a positive lock or stop at the idle position; and

(2)     Require a separate and distinct operation to place the control in the shut-off position.

(e)     For rotorcraft to be certificated for a 30-second OEI power rating, a means must be provided to automatically activate and control the 30-second OEI power and prevent any engine from exceeding the installed engine limits associated with the 30-second OEI power rating approved for the rotorcraft.
