VNAV (Vertical Navigation)
The VNAV sub tab in the Main Menu provides settings for the
vertical navigation feature. These settings create a three-dimensional
proﬁle that guides you from your present location and altitude to a
ﬁnal (target) altitude at a speciﬁed location.
When the VNAV proﬁle is deﬁned, message
alerts help keep you
informed of your progress. The bar on the HSI on the Panel Page
shows your VNAV proﬁle.
To use the vertical navigation feature, your ground speed must be
greater than 35 knots and you must be navigating a Goto or a route.
The “Approaching VNAV Proﬁle” message appears one minute
prior to the initial descent point. The descent angle locks to prevent
changes in speed from altering the proﬁle. The VNAV feature does
not take into account any changes in groundspeed that occur during
the transition from level ﬂight to descent or climb.
At 500 ft above the target altitude, the “Approaching Target
Altitude” message appears, the time to vertical navigation goes
blank, and the VNAV indicator disappears from the Panel Page.
CAUTION: The GPSMAP 196 is a VFR navigation tool and
should not be used to perform instrument approaches. VNAV is
only a VFR navigation aid and is not intended for instrument

Using the VNAV Feature
Use the VNAV (Vertical Navigation) feature to ensure that you are
ﬂying at the proper altitude. The VNAV Indicator appears on the
HSI (Panel Page) as a horizontal bar, as shown in the image on
the next page. A message appears when you are approaching the
VNAV Proﬁle. When the bar is in the vertical center of the HSI, you
are at the proper altitude for the VNAV Proﬁle. Make sure VNAV
Indicator is On in the options menu. From the Panel Page, press
MENU to open the options menu. Select Capture VNAV Proﬁle,
and press ENTER to center or re-center the VNAV indicator on
the graphic HSI. You must have entered a valid vertical navigation
proﬁle and be navigating.

Target Altitude—enter the altitude you want to be at when you
reach your target location. Select Above Waypoint to use ﬁeld
elevation for airports in the Jeppesen database or Above MSL to
specify an exact MSL altitude target.
By—deﬁnes the target location with settings of distance Before or
After a reference waypoint (the ﬁnal destination airport). To set a
target location at a reference waypoint, enter a distance of zero.
—allows you to select any waypoint along the
currently active route (or Goto) as your reference waypoint. The
reference waypoint deﬁnes the target location.
—allows you to select the descent rate.
VNAV Messages—enables and disables VNAV alert messages.
Active Route Page
Whenever you start a route (ﬂight plan) or initiate a Goto while in
Aviation or Water Mode, the Active Route Page shows each point
(waypoint or map item) of the active route, with the point name,
Course, Distance, and several other ﬁelds of information. The
current destination point, the active point, is marked with an arrow .
As you navigate a route, the list automatically updates to indicate the
active point ﬁrst. The Active Route and Route Review Pages share
many of the same features and options.
Press PAGE repeatedly to open the Active Route Page.
Active Route Page
NOTE: If you have created a route (Flight Plan) with a
Jeppesen point that is no longer current after you perform an
update to your Jeppesen Database, the route is locked. You need
to create a new route with current Jeppesen Database points.

Active Route Page Options
Press MENU while on the Active Route Page to open the options
menu. You can edit the route using many of the options in the menu
such as Edit on Map (see page 65 for information), Add Waypoint,
and Invert. You can also change the data ﬁelds to suit your needs.
You can also select an approach for your landing and set your fuel
ﬂow (or plan your route, based on your current Usage Mode):
Select Approach—(Aviation Only) allows you to select the
ﬁnal course segment of a published approach, replacing the ﬁnal
destination airport in a Goto or route with the sequence of waypoints
for the selected approach. The approaches provide only the ﬁnal
course segment, usually from ﬁnal approach ﬁx (FAF) to missed
approach point (MAP), and are based on existing GPS, RNAV,
VOR, NDB, localizer, or ILS approach procedures. All approach
procedures are ﬂown as a sequence of waypoints in the route. To
select an approach and add the waypoints to the route, the ﬁnal
destination in the Goto or route must be an airport with a published
Set Fuel Flow (Plan Route)—allows you to enter information about
your aircraft and route.
Position Data Page
The Position Data Page provides a quick reference for the important
data you want to show while navigating a route in Aviation and
Water Modes. The default page shows a compass ribbon, your
current latitude and longitude, the current date and time, battery or
external power indicator, and eight user-selectable data ﬁelds. The
compass ribbon is shown at the top of the page to show your current
heading with a dark, vertical bar. To stay on course, steer toward the
gray bar (or arrows) until it is aligned with the dark bar.
Press PAGE repeatedly to open the Position Data Page.

Position Data Page Options
With the Position Data Page open, press MENU to open the options
menu. You can set up the layout of the page and change the data
ﬁelds. For an explanation of the data ﬁelds, refer to
page 112 in the
“Appendix.” You can also select one of the following options:
—clears trip information, except the maximum speed and
Reset Max Speed—clears the maximum speed.
Reset Odometer—clears the running total of the distance traveled
since the odometer was last reset.
—clears all trip information including the maximum speed
The Flights tab shows a list of any recorded ﬂights, including date,
route of ﬂight, and ﬂight time. The GPSMAP 196 saves up to 50
recorded ﬂights while in Aviation Mode. Entries on this list are
automatically created for each ﬂight.
The bottom of the Flights tab shows the time of your last ﬂight. This
resets if you select All Unit Defaults from the System tab options
An optional FlightBook software package is available to further
simplify your ﬂight record keeping. For details about FlightBook,
visit the Garmin Web site at
Viewing the Flight Log
Recording begins when your speed exceeds 30 knots and you
gain 500 feet of altitude. The
Route of Flight ﬁeld uses the
nearest airport as the departure airport. The destination airport is
continuously updated as your ﬂight progresses.
If you land and groundspeed drops below 30 knots, the ﬂight entry
is saved and a new entry is recorded when you depart the airport.
A touch-and-go or brief stop of less than 10 minutes appends to the
current ﬂight record, rather than starting a new entry.
Select any listed entry in the log to view additional information.
