ADS-B Display Color

[Andy]

I'm wondering if the icon/symbol of an aircraft on my display varies at all with proximity?

What I wish for is a change in color or better still an alert of some kind that another aircraft is on an intercept course or otherwise closer than I would like. I haven't found any mention of this in the online manual and only changes are to filter based on vertical distance.

Thank you,

Didn't hear back from anyone on this and after another flight I noticed that there is no altitude or distance shown under the ads-b out traffic I see. What does the +1852 mean? I've looked in the online manual and see no mention of any of this.

I've run other EFB software and they all show traffic altitude and distance, seem odd that Avare wouldn't have this capability.

Andy,

If I'm reading the source code correctly, and I probably am not, there are 5 length lines and they are based upon the following:

Length is based upon speed 0 to 500 knots
Short <100 knots
medium short 100 - 199
medium 200 - 299
medium long 300 - 399
long >400

Colors are:
green = well below you, not a threat
blue = well above you, not a threat
red = below you, close, potential threat
magenta = above you, close potential threat

Not quite sure on the logic used to determine the threat level, haven't gotten that far.

The numbers you are referring to is simply the GPS derived altitude relative to you (above or below you).  If the altitude has the suffix of "PA" then the listed altitude is their relative altitude based upon pressure altitude.  If you have a GPS in your ADS-B in unit and it is working you should not have "PA" displayed.

Hope that helps.
