DSC 22_30-80-40 Go-around.
Setting at least one thrust lever to the TOGA detent engages both SRS/NAV modes, if:
The flaps lever is at least in position 1, and
The aircraft is in flight, or
The aircraft has been on ground for less than 30 s (AP disengages and can be re-engaged 5 s after lift-off).
Pretty clear I would say (My bold).
