Unusual spikes
« on: October 26, 2009, 06:46:19 PM »
Hi.
I've just had 2 hits which resulted in 2 spikes on my polar diagram.
One was about 200nm south of me and the other was about 150nm to the north.

Is there any way of finding out what they were.? as the log doesn't seem to record distances.

Here's a shot.

Hi Steve - there is a known problem with the polar diagram producing these spikes. or, if you wait long enough, lobes, that show contacts well beyond our normal range.

AirNav know and are working on it.
