display. The outer arrow gives you the direction to follow.
To use this function you must connect the Vl100 to a GPS and have them both
swtiched on. This function is similar to the previous one but the direction to follow
is not setup by the pilot but transmitted directly by the GPS. So the direction
towards the GOTO is calculated by the GPS. This is shown in exactly the same way
rrow.
To change this setting, go to the 20 wind parameter and press
or
. Above the height vae expressed in meters, you can see the indicatior

altimeters can be adjusted using the parametes ALT1, ALT2 or ALT3, and their
relative pressures, with PRS1, PRS2 and PRS3. To setup the altimetres, select the

3.1.5 Wind Speed
Wind speed is calculated by the VL100 when the GPS is connected and switched
on, and is indicated by a rotating arrow inside the circle, (if the arrow is at my back
that means I’m in a tailwind). This only appears when the wind speed is greater
than 5 km/h, the wind speed can be read next to the word “wind” (when this does
not appear, the wind speed is negligible). When the arrow appears, this indicated
that the wind has started to affect performance and would be better to activate the
wind function, because when we are flying normally, we usually have the relative
airspeed on the display which is more important. You can setup an estimated
wind speed although this will obviously not reflect the actual conditions. The
parameter in question is n.20 wind both for intensity and direction (negative value
= headwind, eg: -20=headwind of 20 km/h). The wind direction is displayed by
an arrow inside the analogue indicator at the center of the display.
the value will start
to flash on the top right of the display. You can change this value from -180 km/h
to +180 km/h by pressing
to memorize the
value.
The intensity of the wind is shown by the 3rd numeric indicator at the top of the
screen when the word “wind” appears. Pressing
switches between ias, wind
and gs. I
3.2 Altimeters
The VL100 has three adjustable altimeters. The three barametric altimeters are
displayed alternately by the 1st numeric indicator on the top right of the screen by
pressing
as magnetic ADF with the same arrow outside the circular indicator. Ro see which
function is in use look at the display> if the outer circle is static then the outer arrow
indicates magnetic north, if the circle is flashing, the arrow indicates the magnetic
direction I set up manually, and if the circle is shadowed the arrow indicates the
direction I must follow to reach the wp. The GPS ADF indicates the direction to
follow to maintain a heading setup bu the GPS. It’s shown on the display at the
center of the screen with a shadowed circle. The direction to follow is shown by a
rotating external a
AS is only visible with the wind probe inserted, and the wind speed
function is only available with GPS or when you setup parametrer n.20. GS,
groundspeed, is only available with the GPS connected and switched on.

anemometer and GPS, set param 20
