Why no VNAV before flap retraction on 737NG?
Hi!
I've been wondering about this for a while now; how come that you shouldn't engage VNAV before flap retraction on the 737NG?
I've heard that this has something to do with the commonality rating with the classic 737:s and that some airlines actually use VNAV to "walk through" the flap retraction speeds on the NG, just as it can be used on all other recent Boeings and Buses. Is this correct?
