Weather Product Age (Table 8-2)
The times for each of the enabled products are displayed
on the right side of the display. Times are based on Zulu
times when the data was assembled on the ground, not the
time the data was received by the FIS sensor. When the age
of a weather product is greater than half of the expiration
time, the product time will change from cyan to amber in
color.
Current weather products use an age stamp,
‘Age: _ _ _’ in minutes. Reported (forecasted) weather
products use a date/time stamp; ‘_ _/_ _ /_ _:_ _’.
