Why still no dive acceleration difference?

[Crumpp]

As long as the efficiciency value is > zero, don't you have some thrust being produced by the propellar?

Sure you have some thrust being produced but it is not EXCESS thrust. It is excess thrust that accelerates the airplane.

In a dive from Vmax, the only excess thrust is the component of weight.


Propeller thrust only accelerates the aircraft within its envelope.
