Garmin GPS 90 - Manual (Page 17)

Most of your in-flight navigation with the GPS 90 will
center around the Navigation and Moving Map pages.
Now that we’re on our way, let’s move on to the Map page:
1. Press the P key.
The GPS 90’s Moving Map page provides extensive
capabilities and information on your present position,
nearby facilities and waypoints, special use airspace and
your active route. Before we go through a few of the basic
features, let’s zoom in for a closer look at our progress:
1. Verify that the map scale field, located at the top of the page,
is highlighted. If it isn’t highlighted, press the U key repeat-
edly until it is highlighted.
2. Press the E key.
3. Press the D key once to change the scale to the 40nm
setting, and E to return the cursor to the default position.
Once you’ve zoomed in to the 40 nm scale, you’ll be
able to see a clear presentation of your plane, nearby air-
p o rts and the special use airspace around Mueller
Municipal Airport (KAUS). The line between 50R and 3R9
re p resents the track-up route from our starting point to
the destination airport, with your present position indicat-
ed by the plane icon. Notice that the plane icon remains
centered on the map, while nearby airports and airspace
move by relative to your present speed and track.
