mentioned by 37575, in the top slot:
"... see pilots pressing the TOGA button to ... go around ... the pilot fail to advance the thrust levers manually for a critical few seconds ..."
You mentioned this observation on MD80 model: Shouldn't the pilot's TOGA-selection trigger the pilots' Flight Director G/A PITCH mode?? That PITCH cmd should be good for the lessor thrust selection (so there still are some good hints for the pilot if he uses his F/D's G/A PITCH suggestion).
Even if the pilot then elects to limit his manual THRUST to a moderate 1.70EPR, or 1.80 (so he can keep the PITCH moderated to SEE the THREAT ahead), then the F/D PITCH display should command a reasonable PITCH attitude for his selected manual thrust.
Seems TOGA selection is a smart idea (for the F/D Pitch suggestion), even while executing a manual G/A in VMC (eg, while avoiding other aircraft at a busy hub after the twr controller goofs the separation and directs pilots to "go around!").
