Sorry I haven't been fully following this discussion so ignore if it doesn't
apply.
But if you don't fully like the idea below, how about changing the color of the
of the target to indicate that it is an old target. I.E> Green if updated in
the past two seconds. Yellow if more than 2.

Subject: Re: [Xcsoar-user] Flarm radar
Mystery solved. Marc from Butterfly just responded to my question on RAS:
> 8 - Does butterfly implement some kind of
filtering which prevents targets from disappearing momentarily due to
loss of signal? This seem the case when comparing to the flarm radar in
XCSoar for example.
Yes, we keep a target active for some seconds ( eight seconds) after losing
reception (ADS-B and FLARM only).
I recommend doing the exact same thing, to be consistent. I know some pilots
disagree, but the only reason to disagree is if you plan to use XCSoar as your
main collision alert system which is not recommended. The implementation in
XCSoar is mostly for situational awareness, and as such, implementing the eight
second delay will be beneficial. Also I trust the Powerflarm and butterfly
folks that they did their analysis to come up with this filtering.
