A system and method for detecting fixed pitch operation of a variable pitch propeller (130) of an engine (110). A command signal for maintaining a rotational speed of the propeller (130) at a reference speed is output. An actual value of at least one of the rotational speed and a blade angle of the propeller (130) is obtained. From the actual value, it is assessed whether an expected change in the at least one of the rotational speed and the blade angle of the propeller (130) has occurred in response to the command signal. Responsive to determining that the expected change in the at least one of the rotational speed and the blade angle of the propeller (130) has not occurred in response to the command signal, operation of the propeller (130) at fixed pitch is detected and an alert output accordingly.
