Abstract
There is proposed a method of controlling an engine aerodyne in the climb phase, wherein a velocity variation law as a function of altitude is imposed. Moreover, there is set a law of variation of the engine speed corresponding generally to progerssive decrease in such speed as altitude increases. Optimization of exploitation costs in the climb phase can be reached mainly by taking into account the engine maintenance costs by means of a wear model.
