SECTION 16 – MESSAGES,

ABBREVIATIONS, & NAV TERMS

OBS key stuck - The OBS Key is stuck in the enabled (or pressed) state. Try pressing the OBS Key again to cycle its operation. If the message persists, contact a Garmin dealer for assistance.

Poor GPS coverage - The GPS receiver cannot acquire a sufficient number of satellites to compute a position and provide navigation.

Power down and re-initialize - The GNS 530 cannot calculate a position due to abnormal satellite conditions. The unit is unusable until power has been cycled off and back on. Abnormal satellite conditions may exist and the pilot may need to use an alternate means of navigation.

RAIM is not available - Receiver Autonomous Integrity Monitoring (RAIM) has determined that sufficient GPS satellite coverage does not exist for the current phase of flight. (The CDI/HSI NAV flag also appears.) Select an alternate source for navigation guidance, such as the GNS 530’s VLOC receiver.

RAIM not available from FAF to MAP waypoints - When performing an instrument approach, Receiver Autonomous Integrity Monitoring (RAIM) has determined that sufficient GPS satellite coverage does not exist to meet the required protection limits. Select an alternate source for navigation guidance, such as the GNS 530’s VLOC receiver (for a VOR or localizer-based approach).

RAIM position warning - Although sufficient GPS satellite coverage may exist, Receiver Autonomous Integrity Monitoring (RAIM) has determined the information from one or more GPS satellites may be in error. The resulting GPS position may be in error beyond the limits allowed for the current phase of flight. Cross- check the position with an alternate navigation source. If the warning occurs during a final approach segment (FAF to MAP), execute the published missed approach.

Scheduler message - [user entered text] - The user-entered scheduler message time has expired, and the scheduler message is displayed.

Searching the sky - The GNS 530 is searching the sky for GPS satellite almanac data or the GPS receiver is in AutoLocate Mode. Allow the unit to complete data collection (approximately five minutes) before turning it off.

Select appropriate frequency for approach

-The aircraft is inbound and within 3 nm of the FAF; and the active VLOC frequency does not match the published frequency for the approach. Tune the standby VLOC frequency to the proper frequency and press the VLOC Flip-flopKey to ‘activate’ the frequency.

Select auto sequence mode - The OBS Key was pressed, disabling auto sequencing of waypoints (in a flight plan or instrument procedure). The OBS Key should be pressed again to enable auto sequencing, because 1) no destination waypoint has been selected or 2) the GPS receiver cannot currently determine its position.
