[A320] Correct time for FLAP 1
Dear Colleagues,
As a general rule it is suggested 3NM before FDP to select FLAP 1. (conditions permitting) However on some straight in approaches you may be cleared for the approach from a high altitude and more than 25NM from the field. In this scenario, you will be intercepting the LOC and GS well before FDP.
In such situations it is advised to activate the approach phase 15NM from the field but when is the correct time for FLAP 1as there is no longer a requirement to be at platform altitude to intercept the GS from below? What I would expect is we would select FLAP 1 prior to GS capture but that would be too early from about 10-15NM resulting in us dragging it in. However I do not want to be on the GS without at least FLAP 1 as per FCOM.
Thanks in advance!
