PARTICULAR PROCEDURES
GPS NAVIGATION (1/2)
Set up conditions
-- Verify if the data base is current.
-- Verify that altitude data is valid for the GPS prior to flight.
-- In case of B--RNAV use :
During the preflight planning phase, the availability of GPS integrity
(RAIM) shall be confirmed for the intended flight (route and time).
RAIM computation is automatically done by G1000 system.
B--RNAV flight dispatch shall not be made in the event of a continuous loss
of RAIM for more than 5 minutes predicted in any part of the intended flight.
When less than 24 satellites are available (or less than 23 if equipment
uses pressure altitude information), the pilot must make sure that RAIM
function is available on the projected route and for the flight period in
B--RNAV areas. An alarm is provided by G1000 system in that case.
When 23 or more satellites are available, the prediction of satellite position
is valid for 7 days. Their predicted availability is ensured for 48 hours by
EUROCONTROL.
When less than 23 satellites are available, the predicted availability of
RAIM shall be confirmed short before each flight.
GPS flight plan
In the active flight plan, addition of a STAR or an approach is always made at
the end of the flight plan. In the scope of these additions, the pilot must pay
attention not to duplicate points.
