Smokey....with due respect..
Both the procedures you mentioned will give me max derated thrust. Say I have 2 standard derates(10% and 20%)and I take off using the 20% derate with an assumed temp. THEN if i hit TOGA a second time OR push the TL's full forward I should get max(ie no assumed temp)of the 20% derate.
But how do i get MAX un-derated power from a derated assumed temp take off. Or is it not possible...
I thought it was possible,but required pushing the TOGA at a certain point in the T/O roll...
But correct me please..
