ABBREVIATIONS, AND NAV TERMS
16.1 MESSAGES
The GNS 530 uses a flashing ‘MSG’ annunciator at the
bottom of the screen (directly above the MSG Key) to
alert the pilot of any important information or warnings.
While most messages are advisory in nature, warning
messages may require pilot intervention.
When the ‘MSG’ annunciator flashes, press the MSG
Key to display the message. Press the MSG Key again to
return to the previous page.
The following is a list of available messages and their
meanings:
Airspace ahead -- less than 10 minutes - The
GPS-calculated course is projected to enter a
special use airspace within 10 minutes. This
message is automatically disabled within 30 nm of
an arrival airport, when an approach is loaded.
Airspace near and ahead - The GPS-calculated
position is within 2 nm of the boundary of a
special use airspace and the course is projected
to enter the airspace within 10 minutes. This
message is automatically disabled within 30 nm of
an arrival airport, when an approach is loaded.
All data referenced to True North - The GNS
530 has not detected a NavData card in the left
data card slot.
Altitude input failure - The GNS 530 is
configured to receive altitude serializer data
(Icarus, Rosetta, or Shadin) and it is not being
received. Or, the data was being received, but has
been interrupted. If a grey code altitude input
is available, it is used instead. 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.
Approach is not active - The approach could
not transition to ‘active’, at 2 nm or closer to
the FAF. Verify that ‘SUSP’ DOES NOT appear
directly above the OBS Key, indicating the auto
waypoint sequencing is suspended. This message
also appears if Receiver Autonomous Integrity
Monitoring (RAIM) has determined that sufficient
GPS satellite coverage DOES NOT exist for the
current phase of flight (along with a ‘RAIM not
available from FAF to MAP’ message).
Approaching target altitude - The current GPS-
computed altitude is within 500 feet of the final
Vertical Navigation target altitude.
Approaching VNAV profile - The aircraft is
within one minute of reaching the initial Vertical
Navigation descent, or climb, point.
Arrival at waypoint [waypoint name] - The
aircraft is within the arrival alarm circle for the
indicated waypoint. The size of the arrival alarm
circle is defined from the ‘CDI/Alarms’ menu
option on the Setup Page.
