109 prop pitch (rpm) and the supercharger

[Crumpp]

Cruising at Dauerleistungen 1.15ata @ 2200U/min our pilot wants to increase speed.

So he puts the propeller to fine pitch until the rpm gauge reads 2400/U min and then increases manifold pressure until the manifold pressure gauge reads 1.3ata.

The airplane acelerates and he coarsens the pitch to maintain 2400/U min.

Pretty simple stuff.....
