Xastir has a mode: "Display last report age", which displays minutes
since the station was last heard.  That text starts out green,
changes to yellow after some number, then red some minutes after
that.  The intent was to help check up on SAR personnel more often
via voice-checks if they weren't being heard from on APRS.  If the
age goes yellow, call then on voice.  If it goes red, perhaps have
another team check on them.
