Re: Fw 190 D cowl flap question
I was under the impression that the cowl flap in front of the supercharger intake did indeed open and close like the rest of the flaps, but after frontline use it was found to effect/alter throttle response and was eventually locked in the closed position.
I believe the best speed performance of the D-9 was found to be with the cowl flaps in a slightly open position, approx. 20%.

Mike
