Cough..
I dont think i understood ur reply since a go around requires flap retraction to 15 from landing flaps right(2eng)? So is it that past this Vref+15 bug u move to 5 from 15 or to 15 from ldg flaps?
I thought the retraction would be according to the green flap bugs.
The G/A procedure requires the flaps to be retracted to 15 as part of the initial actions. At Aa, to retract to flaps 5 requires you to be accelerating (same reasons as pilot pete says) and beyond Vref+15. Again, if similar to 73 classic.
