Has anyone seen the Airshow display on flights? Sometimes during the flight, a white circle appears over a point on a map, and on the bottom of the screen, a text indicates where the circle is -- the geographical name.
Does anyone know what this circle is meant to represent, or is it just randomly chosen by the computer as a nearby point. At first I thought that they might be the currently-tracking VOR by the aircraft, but even on oceanic flights, far beyond navaid range, sometimes, there is a circle still. Also, some of the names do not correspond to any navaid.
The circle always appears on land, never in water.

the spots highlighted on the airshow have nothing to do with navigation. they are just cues to tell the self loading cargo about a small village they might have passed one day at 100 mph. ... for fun and orientation, just feel good you'r not far away from earth...

Yea... I've seen this while flying...
I think it might have something to do with a ground tracking station, even if they don't link up with a VOR. Or possibly it's the closest airport the plane would be diverting to in the event of an emergency? Possible...
