6) Request Interval - Select the requested time between weather
updates. Due to changing satellite and network conditions, the
actual update rate can vary considerably:
■ Maximum Rate - Receives data as soon as new updates
arrive at the NOC, Normally 4 – 12 updates per hour.
■ High Rate - data is queued for delivery at a high rate, up to 6
updates per hour (normally 2 – 6 updates an hour).
■
Normal Rate - data is queued for delivery at a rate of up to 3
updates per hour (normally 1 – 3 updates an hour).
■
Hourly Rate - data is queued for delivery approximately once
per hour.
Note:
Faster rates for request intervals consume significantly more
message units.
7) Weather Types - Allows you to enable/disable the type of
weather information you want to receive. When each box is
enabled, the following data is requested:
■
Text METARs - Text METARs
■ METAR Symbols - Graphical METAR flag symbols

■
SUA Status - Special Use Airspace (SUA) status.
Note:
The Avidyne NOC does not support SUA Status.
Note:
Some data types do not change often during the day and will
therefore be updated only when they change.

are not contained in the Nav database and are depicted only
when received via Datalink.
