Taxiing will be the real *****.
What I'm getting dmeg - is that there is probably a lot of misinformation and misunderstanding of what false LOC signals truly are. No need to get defensive. I am giving logical insight to what some pilots re reporting as problems. Maybe it is even a terminology between our segments of aviation. But you can't really have FALSE CAPTURE OF THE LOC OR GS signal without a failure in the ground based system. As I put forth in an earlier post - maybe what you are calling false captures are really FMS/FGP set-up errors.
