RAIM position warning —Although sufficient GPS satellite cover-
age 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 your current phase of flight. Cross-check your posi-
tion 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 430 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 5 minutes)
before turning it off.
Select appropriate frequency for approach —You are inbound
and within 3 nautical miles of the FAF; and the active VLOC frequen-
cy does not match the published frequency for the approach. Tune the
standby VLOC frequency to the proper frequency and press the
V
key to “activate” the frequency.
Select auto sequence mode —The O key was pressed, disabling
auto sequencing of waypoints (in a flight plan or instrument
procedure). The
O 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.
Select VLOC on CDI for approach —You are inbound and
within 3 nautical miles of the FAF; and the active approach is not a GPS-
approved approach. Verify that the VLOC receiver is tuned to the proper
frequency and press the
C key to display “VLOC” (directly above the
C key).
Set course to [###]° —The course select for the external CDI (or
HSI) should be set to the specified course. The message will only occur
when the current selected course is greater than 10° different from the
desired track.
Steep turn ahead —This message appears approximately one min-
ute prior to a turn in one of the following three conditions: 1) the turn
requires a bank angle in excess of 25° in order to stay on course, 2) the
turn requires a course change greater than 175°, or
3) during a DME arc approach the turn anticipation distance exceeds 90
seconds.
Stored data was lost —All user waypoints, flight plans and system
settings have been lost due to a memory battery failure or system reset.
