Re: Doors popping open in flight

On a single-engine, a door opening is not serious, but a
twin with a door open and the engine on the opposite side
might get interesting. The open door would probably raise
Vmca because of the air flow disruption on the side where
maximum rudder effectiveness would be required.

because single

twins.
