ABNORMAL PROCEDURES
A. If GARMIN GNS 430 navigation information is not available or invalid,
utilize remaining operational navigation equipment as required.
B. If “RAIM POSITION WARNING” message is displayed the system will
flag and no longer provide GPS based navigational guidance. The crew
should revert to the GNS 430 VOR/ILS receiver or an alternate means of
navigation other than the GNS 430’s GPS receiver.
C. If “RAIM IS NOT AVAILABLE” message is displayed in the enroute,
terminal, or initial approach phase of flight, continue to navigate using the
GPS equipment or revert to an alternate means of navigation other than
the GNS 430’s GPS receiver appropriate to the route and phase of flight.
When continuing to use GPS navigation, position must be verified every
15 minutes using the GNS 430’s VOR/ILS receiver or another IFR-
approved navigation system.
D. If “RAIM IS NOT AVAILABLE” message is displayed while on the final
approach segment, GPS based navigation will continue for up to 5
minutes with approach CDI sensitivity (0.3 nautical mile). After 5 minutes
the system will flag and no longer provide course guidance with approach
sensitivity. Missed approach course guidance may still be available with 1
nautical mile CDI sensitivity by executing the missed approach.
E. In an in-flight emergency, depressing and holding the Comm transfer
button for 2 seconds will select the emergency frequency of 121.500 Mhz
into the “Active” frequency window.
