Last year I drew up a 'prop pitch' diagam to help my son better understand the principles of manual prop pitch as it applies to aircraft in IL2 - 'a picture is a thousand words'.

The percentages I have used in this diagram may not suite every aircraft using manual pitch in IL2 - you will have to experiment with the Corsair. I used the excellent Tempest as the basis for these percentages.

You can type in to your aircraft controls in the game the 'Shift values' I have shown. 'Fine pitch' (higher rpm) is used for takeoff and landing. 'Course pitch' (lower rpm) is used for fast cruise and air combat. You will need to experiment with various aircraft to really understand how varying pitch will help through the whole range of flight - stationary, taxying, take-off, climbing, air combat, descent and landing.

I have also included real pilot notes on prop pitch for the Spitfire II. Later Mk's of Spitfires had their throttles linked to the prop pitch mechanism, which could be overided.

Anyway I hope this diagram helps you understand how it all works.
