Sec. 33.45  Calibration tests.



    (a) Each engine must be subjected to the calibration tests necessary 

to establish its power characteristics and the conditions for the 

endurance test specified in Sec. 33.49. The results of the power 

characteristics calibration tests form the basis for establishing the 

characteristics of the engine over its entire operating range of 

crankshaft rotational speeds, manifold pressures, fuel/air mixture 

settings, and altitudes. Power ratings are based upon standard 

atmospheric conditions with only those accessories installed which are 

essential for engine functioning.

    (b) A power check at sea level conditions must be accomplished on 

the endurance test engine after the endurance test. Any change in power 

characteristics which occurs during the endurance test must be 

determined. Measurements taken during the final portion of the endurance 

test may be used in showing compliance with the requirements of this 

paragraph.
