1 " GO AROUND FLAPS 20 "
2 " POSITIVE CLIMB/RATE "
3 " GEAR UP "
1 happened for a reason (if it was called). Bounced landing? Minor/significant windshear?
2 With 145 kts (ish) Vref you can easily establish a positive rate of climb, so the question is was TOGA hit and was the thrust supplied.
3 As PF this is an automatic response whether positive climb is established or not (or not for the V1 cut when PM forgets to call it!)
