You want Take Off thrust on the ramp when TOGA is pushed?
But isn't that what happens in a 737 if you accidently hit TOGA while on the ramp engines running and pushing back and the AT has been armed as part of the before start checks? It used to be that arming the AT was SOP only after you lined up for take off - for the good reason if it was armed earlier (as it is now current SOP) and you stumbled and touched a TOGA button inadvertently, the engines would go to full power. Not a good thing.
