Thanks a bunch guys really appreciated.
It seems this is all done before the preflight checks is that correct? And what is left after preflight checks? Just waiting for doors to be closed?
Also like to add, for the PF - before start procedure for the 737 is this set V2, arm the A/T, LNAV VNAV if needed FMC page to TAKEOFF, as per the FCOM or is this down to each operator?
Also during CDU preflight do you enter the expected RWY and SID? And double check this when getting clearance roughly 10mins before OBT
