
For other areas, use the Garmin WFDE Prediction
program.
This RAIM availability requirement is not necessary if
SBAS coverage is confirmed to be available along the
entire route of flight. The route planning and WFDE
prediction program may be downloaded from the Garmin
website on the internet. For information on using the
WFDE Prediction Program, refer to Garmin WAAS FDE
Prediction Program, part number 190-00643-01, 'WFDE
Prediction Program Instructions'.
For flight planning purposes, for operations within the U.S.
National Airspace System on RNP and RNAV procedures
when SBAS signals are not available, the availability of
GPS RAIM shall be confirmed for the intended route of
flight. In the event of a predicted continuous loss of RAIM
of more than five minutes for any part of the intended route
of flight, the flight shall be delayed, canceled, or rerouted
on a track where RAIM requirements can be met. The flight
may also be re-planned using non-GPS based navigational
capabilities.
For flight planning purposes for operations within
European B-RNAV/RNAV-5 and P-RNAV airspace, if more
than one satellite is scheduled to be out of service, then
the availability of GPS RAIM shall be confirmed for the
intended flight (route and time). In the event of a predicted
continuous loss of RAIM of more than five minutes for any
part of the intended flight, the flight shall be delayed,
canceled, or rerouted on a track where RAIM requirements
can be met.
