ATPL systems question
Hey guys, got a question on something I read during my systems study. Its regarding entering a higher than ambient OAT on the CDUs TAKEOFF page... The book says if a higher than ambient OAT is entered then the thrust management computer will compute a max takeoff thrust based on the hotter temp which is LESS than the max takeoff thrust based on the original temp(ambient OAT i assume).
I dont understand why the max takeoff thrust will be LESS if we have entered a higher than ambient temperature... I would have thought it would have been MORE because increase temp=decrease density so wouldnt the computer calc a higher max t.o. thrust to compensate for the decreased density??
Any enlightenment would be appreciated!! thanks in advance
