I have recently spent some time watching cockpit videos (JustPlanes, PilotsEye, YouTube, etc.) And I have noticed that, while operating the same type of aircraft, it seems like they have different procedures/callouts. For example:
- Slightly different checklists
- Different take off callouts (On the 'bus some say "MAN FLEX, SRS, RWY..." some just say "thrust set" and then of course the speed)
- On Approach/After touchdown. Some wait for a certain altitude which they call out when reached and do a cockpit flow. After landing, for instance on the 'bus, some call out "spoilers up, reverser green, decel, manual braking" while others just go..."spoilers up, reverser green". On the Boeing...I've heard some just say "speedbrakes up"
- I think Swiss pilots checks and calls out the fuel quantity just before take off.
Things like that, are these just different airline-specific procedures, or is it the local CAA that determines what needs to be said and done? Or both?
