Actually... nothing Vidar said actually contradict what I said, except the last sentence.
He even sais in another form what I said:
Quote:

The reason for Constant Speed/Variable Pitch propellors is to Optimize the pitch of the propellor in conjuction with power -i.e.throttle- settings at various stages of flight.

CSP do control pitch and do it constantly to adjust for RPM... I said nothing different.
So for a fixed position of the RPM Lever, then, inside the CS Propellor limits:
- if you increase boost (admission pressure): CSP will adjust pitch and blade angle will increase to keep RPM constant.
- if you decrease boost (admission pressure): CSP will adjust pitch and blade angle will decrease to keep RPM constant.
- If you pull the stick, speed will go down: CSP will adjust pitch and blade angle will increase to keep RPM constant (up you reach the limit of the CSP, then RPM will decrease, and you will risk overtorque if you did set RPM too low)
- If you push the stick, speed will increase: CSP will adjust pitch and blade angle will decrease to keep RPM constant (until you reach the limit of the CSP, then RPM will increase and you'll risk overreving if you did set the RPM lever too high)
I did try to stay as simple as possible to be sure to be understood (since I begin to think my English is so bad that Sniper and Vidar don't understand it.... then I should go to take some English lessons...)
