Could be your radios. Or if you have a GPS tied to your CDI you might have
inadvertently selected "GPS" instead of "NAV" and so the CDI needle was
actually indicating your position to some GPS course instead of the
localizer. I am seeing this error a *lot* in training.


What ACUs will allow you to select GPS display when a LOC frequency is
tuned in on the NAV? I know UPSAT's won't actually select the GPS until
you tune a normal VOR on the associated NAV.

I've seen UPS installs where that's true, and where that's not true. Apparently
it depends on how it's installed.
