alternate airport must be flight planned based upon an LNAV
approach or available ground-based approach which the aircraft is
equipped to fly.
For flight planning purposes, in areas where SBAS coverage is not
available, the pilot must check RAIM availability. Within the United
States, RAIM availability can be determined using the Garmin
WFDE Prediction program, part number 006-A0154-01
(010-G1000-00) or later approved version with GARMIN GA36 and
GA37 antennas selected, or the FAA's en route and terminal RAIM
prediction website: www.raimprediction.net, or by contacting a
Flight Service Station. Within Europe, RAIM availability can be
determined using the Garmin WFDE Prediction program or
Europe's AUGER GPS RAIM Prediction Tool at
http://augur.ecacnav.com/augur/app/home. For other areas, use
the G1000 WFDE Prediction program. This 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 G1000 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, operations within the U.S. National
Airspace System on RNP and RNAV procedures when SBAS
signals are not available, the availability of GPS integrity 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 must be delayed,
canceled, or re-routed on a track where RAIM requirements can be
met or a ground based navigation system can be used.
For flight planning purposes for operations within European
B-RNAV and P-RNAV airspace, if more than one satellite is
scheduled to be out of service, then the availability of GPS integrity
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 must be
delayed, canceled, or re-routed on a track where RAIM
requirements can be met or a ground based navigation system can
be used.
For flight planning purposes, operations where the route requires
Class II navigation the aircraft's operator or pilot-in-command must
use the Garmin WFDE Prediction program to demonstrate that
