Hey,

I just want to check my understanding of the B206 start as I'm finalizing the code for a sim version of it, and am not sure of what exactly ignites the fuel.

How do they "derate" jet engines?

I know that the Allison 250-C20J engine (used in the B206) is 420 SHP which has been derated to 317 SHP for use in the helo.
