If you are on the correct runway when you line up on the centerline for
departure, the localizer needle will be centered. If it is pegged to one
side or the other, you are probably on the wrong runway, or at least have
time to doublecheck what you are doing.

If it's not on your checklist, add "verify the DG matches the runway
heading before advancing power for takeoff." My experience is, that
will catch a failed vacuum pump, not a wrong runway. I also like to
have one of the navs tuned to the ILS frequency and it's NOT because I
never see the localizer needle centered when I fly an approach!


I'd appreciate an explanation for tuning to the ILS.
