Wind
The LX9000 constantly calculates winds using four different methods.
Speed difference
method is used during circling and is taking into account ground speed difference in a single
circle.
Position drift
is calculating wind based on position drift during circling. A minimum
of three circles must be completed to obtain the first wind measurements. The third method
is
combination
, which takes into account also airspeed received from the vario unit.
If the compass module is available wind is also estimated using the wind triangle. Calculated
wind is stored in layers. Layer height is 300 m or 1000 ft and cannot be modified by the
user.
The wind profile is shown on the left side of the dialogue. Yellow coloured altitude indicates
our current MSL altitude. Using the lower-left knob you can scroll up and down through the
wind layers.
Use the
EDIT
button to manually enter wind data. If a new wind direction is entered all
wind directions in range from start altitude to end altitude will be modified. The same
procedure is used for wind speed.
The user can also disable or enable a particular wind method. It is recommended to have all
methods enabled.
Once the wind is modified to suit your needs press the
OK
button to accept the wind values.
The dialogue will exit automatically.
If the
CANCEL
button is pressed the wind dialogue will be closed without applying the
changed values.

Airspace
The Airspace dialogue shows a list of airspace zones in the vicinity of your position. Vertical
and horizontal distances are calculated to all airspace zones in the list.
