SECTION 14 – MESSAGES,
ABBREVIATIONS, & NAV TERMS
14-5
Heading input failure
The heading selection on the external HSI’s (or CDI’s) OBS course selector cannot be read
properly. A Garmin dealer may need to check the installation.
Inside airspace
A GPS-calculated position lies within the boundaries of a special use airspace. This message
is automatically disabled within 30 nm of an arrival airport, when an approach is loaded.
Invalid closest pt of
FPL
A closest point cannot be created from the waypoint entered on the ‘Closest point of flight
plan’ window. This occurs when the selected waypoint is beyond the limits of all legs in the
flight plan, too far away, or when a unique waypoint name for the closest point cannot be
created.
Invalid FPL
modification An attempt was made to modify the final course segment (FAF to MAP) of an instrument
approach. The GNS 430 does not allow the modifications.
Invalid waypoint ident
An attempt was made to create a user waypoint with an invalid name. The GNS 430 does
not allow spaces between characters in the waypoint name.
MAIN processor
requires service The GNS 430 has detected a failure in the main system processor. The GNS 430 is not usable
and should be taken to a Garmin dealer for service.
Memory battery low
The internal battery that sustains user memory is low and should be replaced by a Garmin
dealer as soon as possible. Failure to do so may result in loss of stored data, including flight
plans, user waypoints, unit settings, and satellite data.
Near airspace -- less
than 2 nm
The GPS-calculated position is within 2 nm of a special use airspace boundary, but the
aircraft is not projected to enter the airspace. This message is automatically disabled within
30 nm of an arrival airport, when an approach is loaded.
Need altitude - display
position page
The GPS receiver needs altitude input in order to start and/or continue 2D navigation. Select
the Position Page and verify the altitude reading. If the altitude is in error by more than
500 feet, enter the current altitude as accurately as possible. An inaccurate altitude directly
translate into inaccurate position information.
No altitude input is
being received
No altitude data is being received from RS-232 (Serializer: Icarus, Rosetta or Shadin) or grey
code inputs. If the problem persists, contact a Garmin dealer and check the installation
and installation settings. When this message occurs, no pilot action is required if enough
satellites are available for a 3D position fix (provided no RAIM warnings are present).
However, if only a 2D position fix is possible, the pilot should maintain the GPS altitude
within 1,000 feet of pressure altitude by entering the altitude on the Position Page.
No basemap data
available
The GNS 430 has detected a failure in the built-in basemap (land data) memory. Land data
does not appear on the Map Page. Other unit functions continue to work normally; however,
the GNS 430 should be taken to a Garmin dealer for service at the earliest convenience.
Not receiving input
data on 429 Channel 1 No data has been received on the ARINC 429 channel 1 connection for a period exceeding
five seconds. If the problem persists, the installation should be checked by a Garmin dealer.
