Recently in the sim, the instructor made a remark on the fact that we used this checklist as follows:
Landing Checklist
ENGINE START switch
(operating engine)
. . . . . . . . . . . . . . . . . . CONT
Speedbrake . . . . . . . . . . . . . . . . . . . . . . . ARMED
Landing gear . . . . . . . . . . . . . . . . . . . . . . . Down
Flaps. . . . . . . . . . . . . . . . . . . . . . 15, Green light
PM read every item as it was shown, so "speekbrake-armed" and PF answered again with "armed"
Instructor told us that NNchecklist should be done like normal checklist
PM: "speedbrake" PF: "arm"
Looking forward to your findings.
