De-rated power settings question
I can just not get my head around de-rated take offs.
I am under the wrong impression here... please help me out...
If you are taking off from a 1c in temperature airport, then you need less power to take off as the air is denser.
If you are taking off from a 38c in temperature airport, then you need more power to take off as the air is less dense.
Therefore by my calculation the rotation of the engine will need to be a lot more to push more air into the compressor to get the necessary thrust in a hotter environment.
So I must be mis-reading things when a de-rated take off is one where the engine power is reduced in hotter climates?!
Help - I am wondering lonely as a confused cloud...
