Derated Takeoff on Turboprops
I know that there has been quiet a bit on this subject however I cant find too much relating to a TP. So could some one please help me with this delemer, which is that out company uses derated takeoffs on a GE CT7 and then when we set climb power we are using much higher power levels than what was used for takeoff. IE we might use 84% for Takeoff and then when we set climb power after turning the bleeds back on the power chart will say that we can have 100%. We have no logic in keeping the power set at T/O value until we intercept it on the climb chart. Surely pushing the power leavers forward gives the engine more fuel thus means hotter itt's. Thus meaning defeating the purpose of the derated takeoff. So if anyone can shed some more light on this subject it would be greatly appreciated.
