Nav Data Referenced
To True North – This message appears when a user-defined magnetic
variation of 0 degrees is being used for navigation data.
Nav Data Referenced To
User-Defined Mag Var – This message appears when a user-defined
magnetic variation other than 0 degrees is being used for navigation data.
NAV Super Flag Failure -- This message appears when an internal test
fails for a specific NAV flag output. The KLN 89(B) is still usable, but any-
thing connected to the super flag (such as some HSIs and autopilots)
