Wind

The main display unit 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.
On rear seat device there is additional method called front seat. When front seat method
is selected, device will use wind calculated by front seat only and all other methods will be
disabled. This will ensure that both devices are using same wind for final glide calculations.
The wind profile is shown on the left side of the dialogue. Yellow coloured altitude indicates
our current MSL altitude. Using the ZOOM selector knob you can scroll up and down
through the wind layers.
