ADS-B Stations Page
This page shows the ADS-B stations from which data is being
received. For each station in the list, the page shows the
station’s ID, location, data reception rate, and look-ahead ranges
for TFRs, AIRMETs, and SIGMETs. The data reception rate,
expressed as a percentage, is a measure of recent activity
compared to the maximum activity that has been observed from
the station. The look-ahead range is the radius for which a given
product is provided from that station.
Each FIS-B station periodically broadcasts a "Current Report List"
(CRL) that indicates whether the station is broadcasting TFRs,
AIRMETs, and SIGMETs. Using that list, the IFD can determine
whether it has received all of the reports that it is supposed to
have received. When all of the expected data of a given type has
been received, its look-ahead range will be presented in green.
