TFR
TFR data is also transmitted via Broadcast Datalink. Two types of
TFRs are depicted – active and pending. Active TFRs are depicted
as solid red lines and Pending TFRs are depicted as dashed red
lines, which become solid when the TFR transition time rolls from
pending to active. TFR data cannot be turned off.
Active and Pending TFRs
INDICATIONS OF DATA AGE
The multiple products transmitted as part of the broadcast datalink
service can arrive at different intervals. The age of the current
overlay data is shown in the lower left corner of the map. If a datalink
icing product was selected for display via the “Wx Overlay” key, the
radar age is replaced by the age of the icing altitude data currently
being displayed; the icing altitude slice currently displayed is shown
in the bottom right corner.
NOTE
Datalink Data Position
The in-cockpit radar display depicts where the weather
WAS, not where it IS. The age indicator does not show
the age of the actual weather conditions but rather the
age of the mosaic image. The actual weather conditions
could be up to 15 to 20 minutes OLDER than the age
indicated on the display. Pilots should consider this
potential delay when using in-cockpit radar capabilities,
as the movement and/or intensification of weather could
adversely affect safety of flight.
