alternate means of navigation other than the GNS 530's GPS Receiver.
If "RAIM LS 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 530'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 another !FR-approved navigation system.

sensitivity (0.3 nautical miles). 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 COi sensitivity by executing the missed
