just to clarify one point:
Assume the full rated thrust is 26k and derate 1 is 24k.
If I pick derate 1 and the resulting N1 is 90%
that is 90% N1 of 24K engine
and compare it to a no derate ATM N1. this N1 will be a percentage N1 of 26K ...
so if I get 90% N1 using these two different thrust reduction methods, each 90% is going to effect the engine in a different way ? even I am confused reading this
is that how it works ?
