What about this; after T/O ATC told us 'left turn and proceed XXX waypoint,but my F/O didn't.I told him two times to turn,I tought he might have missed the clearance...He said he can not turn because we still have flaps 5.Anyway I immediately convinced him to turn in captain's way
At cruise I've asked him to explain what was that and he said it is not a good airmenship to turn with flaps because it will be very bad if we loose an engine during turn bla bla bla...Now somebody tell me which department I should go
