3.1.9 Wind Arrow
The Wind Arrow element (Figure
3.13
) is a re-sizable graphical element.
Figure 3.13: Wind Arrow Element
When used in a layout an arrow is draw showing the wind direction relative to the pilot direction (direction
the wind is coming from). For example, if the pilot is facing the wind then the arrow points south (bottom
of the screen). Centered over the arrow is a circle in which a number is displayed showing the wind speed
in Km/h (Figure
3.14
). In the example of (Figure
3.14
) the wind is blowing from East. Both, the wind
speed, and direction, value can be seen in a data elds.
Figure 3.14: Wind Arrow
Note that both wind direction, and speed, are calculated based on the GPS ground speed while the pilot
is turning, so there is no need of wind speed probe. The wind speed calculation accuracy increases with
the number of turns made.
3.1.10 Map Page
The MAP element (Figure
3.15
) provides information to the user about their position relative to waypoints,
cylinder edges and the pilot's trace or track. This element can be resized and moved around the screen.
