2011 pilot's life was lost in gliding competition here in Finland. Both
gliders had FLARM installed, and they were in glide near each other several
minutes before collision. See the summary (English) of this document;
http://www.turvallisuustutkinta.fi/Satellite?blobtable=MungoBlobs&blobcol=urldata&SSURIapptype=BlobServer&SSURIcontainer=Default&SSURIsession=false&blobkey=id&blobheadervalue1=inline;%20filename=Tutkintaselostus%20B1_2011L.pdf&SSURIsscontext=Satellite%20Server&blobwhere=1342016078074&blobheadername1=Content-Disposition&ssbinary=true&blobheader=application/pdf
The LED based systems tell you in which direction the other glider is, but
not the distance. If it comes and goes, you assume that the other glider is
far away from you, even if it's 50 meters behind of you. Dipole antennas
have blind spot, when the antennas are pointing each others. I have seen
SeeYou playback of logger files of this accident, it was frightening.
Therefore I agree with Henrik, we should have a way to let FLARM targets
stay few seconds longer visible in XCSoar when connection was lost. What
harm would that be? We are aware of something, that does not exist exactly
where our display shows - but is somewhere there. If it was 3 miles
distance when it disappeared, then who cares. But if it was 300 feets front
and under you when it disappeared, would you like to get a reminder that
there might be someone near to you, and closing?
