Oh all right, the EASA definition agrees with you, I'll get my coat then...
Ah, nice one ‘minga.
You are right. Just like a Rotary Aircraft those propeller blades (Inclined planes) are producing a force at right angels to the Relative Airflow over the blades:
Lift by standard definition.
Indeed in any propeller driven aircraft the propeller produces a force at Rt Angles to the Relative Airflow over the propeller blades. But I will continue, for clarity at least, to call this force thrust rather than lift.
For me Rotary Aircraft are Rotary Aircraft not Aeroplanes. But I don’t mind what the general vernacular is.
