Request: Instructions on how to load Derates

[aldent95]

First off, I love this tool. Makes my life so much easier being able to calculate takeoff and landing data for the airliners that I fly in the sim.

However I would like to help make it better by contributing to the performance data files by adding more flap settings and de-rated thrust settings.

I understand how to do the flaps. Take the charts from the FPPM and convert them into tables similar to the ones in the FCOM then load into the XML.

What I don't understand is how to get the de-rate data.
Looking at the code I can see that the 4 lines are full thrust weight, dry weight, wet weight and climb weight, but beyond that I have no clue.

If you can give me some instructions I will happily do the boring job of doing the conversions and loading them up, starting with the B738.

Additionally, which engines did you use for the current B738 data? I can't seem to figure out which one matches the FCOM and FPPM data I've found.

Cheers

I would like to do this as well. It would be so much better for users and developer with clear instructions on this subject.
