Messages, Abbreviations, and
Navigation Terminology
Messages
The 400W-series unit uses a flashing “MSG” annunciator
at the bottom of the screen (directly above the MSG key) to
alert you of any important information or warnings. While
most messages are advisory in nature, warning messages
may require your intervention.
Whenever the “MSG” annunciator flashes, press the
MSG key to display the message, when pilot workload
allows. Press MSG again to return to the previous page.
The following is a list of available messages and their
meanings:
ABORT APPROACh — Loss of Navigation —
Execute
missed approach using other navigation equipment.
Airport terrain database integrity error — The
400W-series unit has detected a problem with a database
on the Terrain data card. The data is not usable and the
card should be returned to your Garmin dealer.
Airspace ahead — less than 10 minutes — Your 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 — Your GPS-calculated
position is within 2 NM of the boundary of a special use
airspace and your course is projected to enter the airspace.
This message is automatically disabled within 30 NM of an
arrival airport, when an approach is loaded.
All data referenced to True North —
The unit does not
have a valid aviation database, so it cannot compute mag-
netic variation.
Approach downgraded — Use LNAV minima —
This
message will occur 60 seconds prior to the FAF if flying
LNAV+V, L/VNAV, LP, or LPV approaches and WAAS
integrity parameters have fallen below minimal limits. As
a result, vertical guidance has been discontinued and the
LP, LPV, LNAV+V, or L/VNAV approach you were flying has
been downgraded.
Approach is not active — The approach could not transi-
tion 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.
Approaching target altitude — The current GPS-com-
puted altitude is within 500 feet of the final Vertical Naviga-
tion target altitude.
Approaching VNAV profile — You are within one minute
of reaching the initial Vertical Navigation descent point.
APR Guidance Available - Use PROC before A/P APR
—
For units configured with the KAP140 or KFC225
autopilot, this message reminds pilots, when they turn
on course to the FAF, that they need to enable autopilot
outputs (by pressing
PROC and selecting “Enable A/P APR
Outputs?”) before switching the autopilot control panel to
APR.
Arrival at waypoint [waypoint name] — You are 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.
Audio database integrity error — The 400W-series unit
has detected a problem with the built-in HTAWS Audio
Database. HTAWS audio alerts are not available. The unit
should be returned to your Garmin dealer for service.
Aviation database integrity error — The 400W-series
unit has detected a problem with a database on the Nav-
Data
®
card. The data is not usable and the card should be
returned to Jeppesen or your Garmin dealer for service.
