Messages

The 500W-series unit uses a ﬂashing “MSG” annun-

ciator 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 mes-

sages 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 mean-

ings:

ABORT APPROACH — Loss of Navigation — Execute

missed approach using other navigation equipment.

Airport terrain database integrity error — The 500W-

series unit has detected a problem with a database on the

TAWS/Terrain data card. The message “<database name>

database integrity error” indicates the data base in error.

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 nautical miles of an arrival airport, when an

approach is loaded.

Airspace near and ahead — Your GPS-calculated posi-

tion is within 2 nautical miles of the boundary of a special

use airspace and your course is projected to enter the

airspace within 10 minutes. This message is automatically

disabled within 30 nautical miles of an arrival airport, when

an approach is loaded.
