Making an approach in config 2 then innitainating a go around and moving the flap lever up one stage in this condition would not be a wise idea as this has a good possibility of a stall
EGKK you are wrong on both counts. First Stalling speed is not dependant on flap lever but actual surface position which in this case remains at 2. Secondly incase of a GA you do not retract flap one step with double hydraulic fail but maintain the conf.
