LOSS OF GPS NAVIGATION :
“LOI”, “WARN” OR “DR”
ANNUNCIATIONS LIGHT ON
In case of loss of RAIM function, the navigation information
remains available but its integrity is no longer controlled.
-- If RAIM loss occurs out of B--RNAV area, the aircraft must not enter
B--RNAV area.
-- If RAIM loss occurs in B--RNAV area, GPS navigation can be continued
as long as cross--checkings done with conventional means (VOR,
DME, NDB and dead reckoning elements) enable making sure that
B--RNAV accuracy criteria are observed. When this condition is not
met, the Air Traffic Control must be contacted to return to conventional
navigation.
If GPS navigation information is lost or declared not valid,
use the
other available navigation means. If this occurs during instrument
approach final phase, a go--around must be made, except if the other
approved radio means to perform approach are displayed and available.
