BF-109 Prop Pitch Lever

[Blackdog_kt]

It's like shifting gears in a car.

high rpm = low gears
low rpm = high gears
driving uphill = climbing
driving downhill = diving


In that sense, if i want to pick up speed in a dive i'll do what i do in a car to accelerate when driving downhill: step on the gas pedal and shift to a higher gear = increase throttle and decrease RPM

However, if i want to make sure i don't go too fast in the dive i'll do what i do in a car if i want to go slower: let go of the gas pedal, shift to a lower gear and let it act as a brake as the car rolls downhill = pull the throttle back and set pitch for increased RPM

In other words, if you want to get good performance in a dogfight you'll have to keep changing the prop pitch all the time. Otherwise you might get poor acceleration in a dive or reduced climb rate and it can get you killed.

Hope it helps.
