The .air file is at the "Behaves fairly Well" point. In fact, I´d say it "Behaves Very Well"!
It is the .air file that had the Hurricane´s slightly corrected Efficiency Table 511, and the 15-65 Pitch CV Propeller, now adjusted to 18-35 Pitch.
> Take-off behaviour is correct, as before, and any low-pitch-limit increase will be less convenient.
> High pitch limit is fine, as the maximum needed at the tested heights was 34.9, and performance is the same as it was before.
> All Maximum Speeds and Criuse Speeds are correct, as is the rate of climb, which I hadn´t tested before, managing very well with the specified 1260 fpm initial climb, which is first at pitch 19, and later goes up to 24-25.
The results look fine and I am very pleased with the performance at present. ...
