"NO DISPLAYED NAVAID"

Googling and searching showed very little on this question...

I often (always??) get this showing on the FMC at some stage. What is its meaning/significance?

Thanks

Hi Martin,

This indicates that the aircraft GPS is being used on it's own without support from ground stations relaying the signal. See FCOM details below for more info!

Hope that helped! 🙂
