Based on several discussions it seems that people have been experiencing inaccurate GPS data recently.

Would it be possible to have a “RAIM-like” indicator that shows the current GPS accuracy? Other EFB apps do this already.

To avoid clutter, it could perhaps normally be hidden, but appear if accuracy is less than some vertical/horizontal threshold?

What sort of presentation do you imagine this having?

There is already a small triangular coloured flag in the top left-hand corner of the Altitude instrument indicating the accuracy of the GPS derived altitude which, of course, is directly correlated with GPS accuracy.

Tim,

I suppose the error / presentation method would depend on what kind of GPS reliability metrics you have available on each platform.

It could be as simple as a prominent red warning box saying “GPS ACCURACY LESS THAN 100M” or something?

Mike — great point and I’d missed those little flags. I guess I’m saying something more prominent for a larger inaccuracy might be handy.

Ah, I didn't know. How does that work? I currently see a blue flag. What colours could this flag have, and how does this translate to accuracy?
