Density Altitude and Percent HP Available English Units http://wahiduddin.net/calc/calc_hp_dp.htm Metric Units http://wahiduddin.net/calc/calc_hp_dp_metric.htm Also, the following propellor efficiency calculator is quite useful if you have some actual performance numbers (TAS at RPM at DA) http://www.gylesaero.com/freeware/propcalc.shtml If anyone has questions about these, let me know and I'll try to walk you through how I've used them.
