INDICATIONS OF DATA AGE
The multiple products transmitted as part of the Broadcast
Datalink service can arrive at different intervals. Two indicators at
the bottom corners of each map provide an easy-to-use indication
of data age. 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.
