Hi,

I notice that I get on the ND the wording:

EFIS mode/NAV freq disagrees.

What does that mean and how does not get rid of it.

It's likely to be because you have the EFIS set to APP mode but your nav radio is not tuned into an active ILS frequency.

Or Vice Versa! Have an ILS Freq Programmed and are not in App Mode!
