Map Airspace Options
The next listing on the map option menu is ‘AIR-
SPACE’, which allows you to designate a minimum map
scale at which an airspace will be depicted or allows you
to turn off the selected airspace category entirely. Each
category has 19 adjustable settings, from 0.2 nm to 500
nm and ‘OFF’. The ‘OTHER SUA’ airspace category
includes alert, caution, danger, warning, and training
areas. The ‘OTHER CTRL’ category includes control zones
(Europe) and control tower areas (typically Class D)
which are within five nautical miles around an airport
with a control tower and up to 2,500 feet above airport
elevation. Prohibited airspaces are not selectable and will
always be displayed. Turning off an airspace from the
map options menu simply removes it from the map dis-
play and
DOES NOT
turn off the alert messages for that
airspace category. For more information on SUAs and
alert messages, see page 59.

Track Log Options
At the bottom of the map option menu is the ‘TRACK
LOG’ selection. The corresponding track setup page lets
you manage and erase the GPS 92’s track log data. (A
track log is merely an electronic ‘breadcrumb trail’
recording of your path, showing where you’ve been.)
From the track setup page, you can select whether or not
to record a track and define how it is recorded.
The ‘RECORD’ option lets you select one of three
recording options: ‘OFF’, ‘FILL’ or ‘WRAP’. The ‘FILL’
option will record track log data until the maximum
memory of 2048 points is reached, then stop and provide
a “Track memory full” message. The ‘WRAP’ option will
continuously record track log data by wrapping through
available memory and replacing the oldest track data
with new data.
The map airspace setup
page allows you to desig-
nate a minimum map scale
or to turn off a selected air-
space category entirely.

the following airspace
categories:
• Class B / CTA
