Assumed temperature reduced thrust
An answer i should know but here goes....
When we derate and then use an assumed temperature I've noticed that when T/O thrust is set it is not corresponding with the N1 reference bug(green carrot). Now i appreciate that when we assume we still have some extra thrust available and can set thrust to the n1 reference bug but my question is why when we assume does the computed N1 not match the N1 refernce bug on the N1 dial.
Thank you
