File Description: We're all waiting for the 777 profile for TOPCAT. But until it's out, I thought I needed a way to validate my derate at takeoff without the use of TOPCAT. So I made this small excel file, that can help find the optimal derate. It is absolutely no equivalent to the B737 dispatch sheet that I made for the NGX. And it is not going to be. It is based on the PMDG 777 FCOMv1 tables (PD.30).
