TRK Up Arc/TRK Up 360
This ring is marked in nautical miles from your airplane
with the ring placed at one half the distance of the map
scale. For instance if you have the map scales at 50 miles,
the ring will be at 25 miles. The ring will change
automatically as you change the map scale. The Terrain
function display is always in the Track Up mode.
Set Barometer
Use the Set Barometer option to enter the correct
barometric pressure for your area or adjust the current
value. This option is best for making large changes. The
BARO +
and
BARO -
keys are more useful for minor
corrections. Use the
UP/DOWN
arrow keys to increase or
decrease the values. Use the
LEFT/RIGHT
arrow keys to
move between characters. Press the
ENTER
key to save the
displayed barometric pressure.
A “Confirm Current Baro” message is displayed at the
initial power-up and again once every 30 minutes of
operation as a reminder to check your baro setting.
TER Data Flag
The TER flag will appear if no terrain data is available
for the advisory coverage area.
