RAT5
Very well said, that's exactly what I expect from the boss in the left seat. Make me feel like its my idea rather than blatantly tell me what to do.
I'm the kind of pilot that likes to "stretch it a bit". Never wanna drag the aeroplane in, stay on Flap 5 for as long as possible (5nm in most cases. I fly in an environment where ATC gives separation of 10nm on approach most times).
I find that most new captains on type are not comfortable with this approach and want me to configure much earlier so I always brief what I'm going to do and I have an idea of their approval (or not) way before the approach phase.
I hardly use flaps 10, only use it to get the speed to exact flaps speed for separation when behind a slower aircraft and catching up. I prefer to wait a bit longer and use the landing gear.
