Following your Flight Plan
When you have created and started your flight plan (or route), the
GPSMAP 496 guides you to the destination using a variety of tools.
notE: After you perform an update to your Jeppesen database,
verify that all of your flight plans (routes) in your unit are still
current. If there is an obsolete Jeppesen aviation point in a saved
route, the route is locked and unusable. You need to create a new
route with current Jeppesen database points.
Track Your Progress on the Map Page
On the Map Page, your current location is shown as an airplane
(when in Aviation Mode). You can see how the airplane moves
across the map; this is a graphic view of your flight. Your route is
marked with a magenta line. The airplane should be on top of the
magenta line as you move. When you are on the magenta line, you
are directly on course. For complete information about the Map
Page and the features of the Map Page, see pages 29–36 .
notE: In Aviation (and Marine) Mode, the Go To line and
navigation guidance are fixed. The From point is the location
where the Go To was initiated. In Automotive Mode, the Go To
line on the map is constantly updated to your present location.
Terrain and Obstacle Changes
Press pagE to open the Terrain Page, and watch the changes in the
terrain and the obstacles you are flying over with the Terrain Page.
Terrain and obstacles that are less than 100 feet from your aircraft
are shown in red. For complete information, see page 37 .
View the HSI on the Panel Page
You can use the Panel Page to view the HSI, your bearing to the
course, and other information such as speed, altitude, and ETA. Use
the compass in the center of the page to determine if you are on the
proper course. Also, you can help keep the aircraft within the VNAV
profile when viewing the VNAV indicator. For complete information
about the Panel Page, see pages 40–43 .
Alerts
As you travel, a variety of alerts appear on your current page, such
as Airspace, Terrain, Obstacle, and Descent Rate Alerts. When
an Airspace Alert pops up, press nrSt to view the Airspace
Information. When a Terrain or Obstacle alert pops up, press pagE
or nrSt to open the Terrain Page. From here you can view any
terrain and obstacles that might become a problem to you. Possible
points-of-impact are shown as Xs. Adjust your altitude to avoid the
obstacles and terrain.
