Hi all,
I differ on the B747 Classic A/T ops - The FE calls manual thrust if the predicted thrust hasen't been set by 80 kias, or THR HOLD isn't indicated, if the A/T is being used.
And the FE then sets/trims to the power required.
Then, if using reduced power, the Captn decides, for whatever reason, to use maximum power, as he can, he will call 'set GA power' (NOT max power), as GA power above 80 kias IS MaxPwr below 80 kias.
Setting Max power over 80 kias will overboost the engines!
Cheers
