In a nut shell it is the angle of the propeller blade as it cuts through the air.
.041 Safety Wire gave you some setting regarding the P-51.
Some planes had manual pitch control and had to manually change the pitch settings of the propeller to match the power/throttle settings for a particular operation and altitude.
Other planes had the prop pitch controlled automatically. Most US aircraft used automatic propeller control. The pilot would set the RPM of the propeller of to a certain speed based on the type of power setting it was using:
War Emergency Power
Military Power
Normal Power
Cruise
The automatic propeller control would keep the RPM constant (when the aircraft was fitted with a constant speed propeller). When the throttle was advanced or retarded the RPM would change initially, but the propeller blade pitch would automatically change to bring the propeller RPM back the setting the pilot had set. The F4U Corsair and F6F Hellcat used the following:
War Emergency Power = 2700RPM
Military Power = 2700 RPM
Normal Power = 2550 RPM @ 44" MAP below 8,000 Feet, Neutral Blower (Super Charger 1 in game), 48" MAP 8,000 Ft, Low Blower (Super Charger 2 in game), 48" MAP @ 15,000 FT High Blower (Super Charger 3 @ approximately 18.000 ft in game). You can tell when to switch super charger settings because given the set RPM you have to advance your throttle beyond 100% to maintain the MAP at a given altitude and Super Charger setting.
Hope this helps explain it a bit. Will keep the temperature down so you are not close to overheating when you enter combat in the game. May mean the difference of egressing or burning up your motor before egressing.
