I've found the following websites to be very useful for playing "What If?" with propellor pitch.



Density Altitude and Percent HP Available



English Units

Metric Units

Also, the following propellor efficiency calculator is quite useful if you have some actual performance numbers (TAS at RPM at DA)

If anyone has questions about these, let me know and I'll try to walk you through how I've used them.
