A Question or 2

[Hamish McTorsk]

Does anybody have an idea why planes sometimes show up on the interface but not on the screen, do I need to change something in my setup ??
Also:
Why do flight sometimes show up without the aircraft icon but have a circle within a circle. ? (Delta Airlines flights always do this)

Thanks.

See the video on the tutorial page regarding aircraft nor showing on the map:

It's on the AirNav YouTube channel too:

The circle appears when the aircraft is not transmitting heading (track) information.
