WEATHER DATA AND IMAGERY
WARNING: Do not use the indicated data link weather product age to determine the
age of the weather information shown by the data link weather product. Due to time
delays inherent in gathering and processing weather data for data link transmission, the
weather information shown by the data link weather product may be significantly older
than the indicated weather product age.
age of the weather information shown by the data link weather product. Due to time
delays inherent in gathering and processing weather data for data link transmission, the
weather information shown by the data link weather product may be significantly older
than the indicated weather product age.
WARNING: Do not use data link weather information for maneuvering in, near, or
around areas of hazardous weather. Information contained with in data link weather
products may not accurately depict current weather conditions.
around areas of hazardous weather. Information contained with in data link weather
products may not accurately depict current weather conditions.
Weather is presented in Widgets (as text), map overlays, preflight weather briefings,
or with National Weather Service static aviation weather maps. To receive up to date
weather information, the device must have access to a wireless network (Wi-Fi or
cellular) or a GDL 39.

RADAR
Weather radar data is collected from radar sites across the United States, Canada,
and select overseas locations. It is combined into a mosaic for easier display and
analysis.
analysis.
The radar data displayed is not real-time. The lapsed time between collection,
processing, and dissemination of radar images can be significant and may not reflect
the current radar synopsis. Due to the inherent delays and the relative age of the
data, it should be used for long-range planning purposes only. Never use radar data
to penetrate hazardous weather. Rather, use it in an early-warning capacity for pre-
departure evaluation.

Composite data from radar sites in the United States is shown. This data is
composed of the maximum reflectivity from the individual radar sweeps at different tilt
angles of the radar beam with respect to the ground. The display of the information
is color-coded to indicate the weather severity level. Colors are used to identify the
different echo intensities (reflectivity) measured in dBZ (decibels or Z). “Reflectivity”
(designated by the letter Z) is the amount of transmitted power returned to the radar
receiver. The dBZ values increase as returned signal strength increases. Precipitation
intensity is displayed using colors corresponding to the dBZ values.
