will result in a no FD raw data GA, also undesirable.
Undesirable, maybe; difficult for a properly trained pilot, no.
The thrust lever position for a Go Around is pretty simple - full forward until it is stopped by the forward limit of the slot it moves in. Rather hard to forget that one.
It was the case on the Boeings that I flew that GA thrust was a 'straight arm' not to the stops. It is also the case that full power is not necessary on an all engine GA. However, if made within kissing distance of the ground I can understand why guys might want all they can get, initially.
On B777 FBW is the power/pitch couple taken care of by more automatics and much of the pitch trim removed? On steam driven a/c it could be quite a handful at full power to keep the nose from being over enthusiastic as you pull back and power up.
