Detailed Operation
GDL 69/69A - FIS
Product Times
Product times are shown on the lower portion of
the display and cannot be hidden. The times for each
of the enabled products (up to four at a time) are
displayed. The time format shows day of month and
then hours and minutes in Zulu time. For instance,
METAR: 24 2036Z would mean that product time
reported was on the 24th of the current month at
20:36 Zulu time. The following product times are
shown: Nexrad for NEXRAD radar, METAR, Echo
Tops, Cloud Tops, Lightning, and Winds Aloft.
Times are Zulu times when the data was assembled on
the ground, not the time the data was received or dis-
played by the FIS sensor. The Winds Aloft product time
includes the selected Winds Aloft Altitude.
Product times are shown in white when they are
initially shown and change to blue and then yellow
as they pass certain age thresholds. A product time
aging table is shown below. For a GMX 200 that does
not have time available from a GPS receiver, age is
based on the time the data was received from the GDL
69/69A sensor. In this case, the age of the data may be
older than what is shown by the color coding.
Animating Nexrad, Cloud Tops, or Surface Analy-
sis products will disable the depiction of other enabled
products. The product time for the other enabled
products will be displayed as “N/A” while animation is
active.
