How many people select gear down flaps 15, without waiting for green landing light annunciator lights to appear or do people correctly pause before flap extension.
Eh?
Nothing about
pausing in any of my -NG manuals. (Although I will concede that the way Pilot Monitoring duties are written it "could" be read that way)
As B737SFP writes the classics (-300/400/500) were a different beast, and selecting Flap 15 before you had the gear down with three greens did set off the Config Warning horn which couldn't be silenced.
