3.1.7 Altitude graph
The Altitude graph element (Figure
3.11
) corresponds to a graph of barometric altitude versus time.
Altitude is shown in the vertical axis graduated in meters with time shown on the horizontal axis graduated
in seconds.
Figure 3.11: Altitude Graph Element
The range of the horizontal axis is xed and corresponds to 240 seconds (4 minutes), while the range of the
vertical axis is automatically adjusted in order to accommodate the gained height. In reality the altitude
graph element is a plot of the absolute barometric altitude over the last 4 minutes of ight (Figure
3.12
).

3.1.8 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.
