Funny one tonight. On second flight, whilst int he cruise at FL100, the map turned off. Big white square where the map is., with a big red cross though it. I noticed later that the PWR LED at the bottom left also went to red. ATC still continued to advise me and the flight plan segments moved as per normal. Just no map.

I tried different map types, Google, Terrain, etc. All the same. The Taxi and Appr buttons on the right were also highlighted, and I had not touched them. Turning them off did nothing.

Apart from that, 2 faultless flights.

 

Sounds like an error occurred in the Map software.  Rare event, thank goodness.

 

I forgot about the log. I include this segment as it seems most relevant.

Thanks for the info.  It looks like it's what I thought.

Same problem here Version 2.5.0.0

Thank you and Regards,

Richard,

I suspect this is the same internal error of the map control.  It seems to happen when the map is being asked to do a lot of drawing and re-drawing.  The most common settings that seem to lead to this are having the Map Centered on the aircraft and having lots of AI Traffic showing.

Fortunately, this is not a consistent error and hopefully won't recur regularly.
