On this Garmin GMA 340:
- the outer marker is blue and is designated O
- the middle mark is amber and is designated M
- the inner marker is white and is designated A and placed on the far left.
I looked at the GMA 340 Manual and could not find an answer although it does say Airway/Inner Marker.
Why would it say Airway if this is what the A indeed stands for and why even have an inner marker because that Garmin can't do a Category II approach?
