Flight Mode Annunciator

[Tsolis]

Hello Just Flight,

I have a question regarding the Flight mode Annunciator Panel .

What means the Symbol "OUTER' and "AIRWAY" on the Flight mode Annunciator Panel

[Avionic]

Outer, middle, and inner will be for passing the different marker beacons (https://en.wikipedia.org/wiki/Marker_beacon).
Not sure about the airway indicator. Have almost exclusively flown it without the FMC, but could be related to flying programmed airways from that, though i would think that would simply display as LNAV instead?

@Avionic thank you for reply . So this means when i get thissg in the flight Mode Panel i overfly an outer Marker?
