gums: TOGA actions by the system?
It depends on the flap lever position.
If the lever is in the zero (up) position it will command thrust only, TOGA, max thrust setting.
Should the flap lever be in “one” or more, it will command the Flight Director bar, and A/P, if engaged, to Go Around. Pitch channel will go to Speed Reference System.
As you know, above a certain altitude, climb, MCT and TOGA are the same, as far as EPR or N1 are concerned.
