ED Decision 2003/13/RM

(a)     General. The power-plant limitations prescribed in this paragraph must be established so that they do not exceed the corresponding limits for which the engine or propeller is type certificated.

(b)     Take-off and continuous operation. The take-off and continuous operation must be limited by:

(1)     the maximum rotational speeds (r.p.m.);

(2)     the time limit for the use of take-off power;

(3)     the maximum allowable cylinder head, oil, and liquid coolant temperatures, as appropriate; and

(4)     the maximum allowable manifold pressure or any other parameter limiting the engine power if the engine is equipped with a continuously variable pitch propeller.
