the pilot is outside a visible airspace area then a gray line is used to draw the area, whereas if the
pilot is inside the airspace then a black line is used instead. Note that being inside a airspace area
(2D) does not mean that the airspace is being violated, since the pilot can be above, or below the
defined 3D shape. In order to have more information about possible airspace?s violation, some data
fields should be added to the layout. This data fields are Distance to CTR, Altitude to CTR, and
CTR Status (Figure
3.10 ).
The Dist. CTR data field shows the shortest horizontal distance to the nearest airspace line.
This distance is always positive. Similarly, the Alt. To CTR shows the shortest vertical distance
to nearest airspace line. Unlike the horizontal distance, the vertical distance can be negative. A
positive vertical distance indicates that you are outside the airspace, whereas a negative distance
indicates that you are inside the airspace. Additionally, the
CTR status field will indicate if an
airspace is being violated by displaying Violating . If the pilot is not violating the airspace but it
is inside a predefined margin then the messages Altitude Imminent , or Position Imminent will be
shown.
Figure 3.10: Airspace Map and Associated Data Fields
When the page contains an airspace map element, the UP, and DOWN keys, can be used to
change the map scale: pressing the UP key will decrease the scale, and the DOWN key will increase
the scale.
3.1.7 Altitude graph
The Altitude graph element (Figure 3.11 ) corresponds to a graph of 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 fixed and corresponds to 240 seconds (4 minutes), while the
