Using selected speed and flaps to initiate initial approach, then with gear down and selecting flap 3 I’ll then go back to managed speed to reduce workload (this is what I’ve seen in videos). However, flaps 3 and 4 don’t ever reduce speed to Vapp speed as shown in MCDU, so unless I go back to selected speed I’ll come in too fast. What am I doing wrong? Is this something to do with the timing of when you activate approach phase on the MCDU - if activate and then go selected (for flaps 1&2), can you then not get back into approach phase on MCDU to coordinate speeds and automatically manage speeds for flaps 3&4?
