To calculate true airspeed and density altitude:
1. From the
E6B
tab, highlight the
Indicated Altitude
field (at
the top of the page), and press
ENTER
.
2. Use the
ROCKER
to enter the altitude shown on your
altimeter. Press
ENTER
when finished.
3. Repeat steps 1 and 2 to enter the
Calibrated Airspeed
,
Baro Pressure,
and
Total Air Temperature
. (For
Calibrated
Airspeed
, use the speed shown on your airspeed indicator.
Use the current altimeter setting for
Baro Pressure
.
Total
Air Temperature
is the temperature of the outside air
including the heating effect caused by speed. For most
aircraft, this is the temperature reading on a standard outside
air temperature gauge.) The calculated figures for
True
Airspeed
and
Density Altitude
are shown in the designated
fields.

To calculate winds aloft:
1. Follow the steps in the previous procedure to determine true
airspeed.
Or
Use the
ROCKER
and
ENTER
keys to manually enter a true
airspeed figure in the
True Airspeed
field.
2. Use the
ROCKER
to highlight the Heading field, and press
ENTER
.
3. Use the
ROCKER
to enter the aircraft heading shown on
your directional gyro or compass. Press
ENTER
when
finished.
The calculated figures for Head Wind, Wind From, and Wind
Speed appears.
NOTE:
If a True North reference is currently selected as the
heading reference on your GPSMAP 196, you must enter
Heading using a True North reference to determine winds
accurately.
