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
■ AIRMETs / SIGMETs - AIRMET/SIGMET
■ 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.
■ TFR Status - Temporary Flight Restrictions (TFRs). TFRs
are not contained in the Nav database and are depicted only
when received via Datalink.
