TIS outage
Does anyone know how to tell if the Traffic Information System uplinked by
Mode S is in service or not? My Garmin 530/ GTX 330 says "traffic
unavailable" and passes all of the diagnostics, but when I called ATC and
flight service they said Mode S was operational.
Is there any other way to get information on whether the uplinks are working
or not?
TIA
