4.7.13 Airspace settings
Figure 4.32: Airspace Settings
This menu allows the user to dene certain parameters related with airspaces. Each of the parameters
can be changed using UP, and DOWN, keys. Pressing the ENTER key conrms the value and jumps to
next parameter. Changes can be undone by pressing the MENU key. As shown in Figure
4.32
there are 5
parameters related to the airspace which are explained in Table
4.8
.
Table 4.8: Airspace Menu Settings
Function
Description
CTR dist. Th
Minimum horizontal distance that a pilot can be from an
airspace without triggering an airspace warning. If this thresh-
old is passed a warning is emitted (event).
CTR alt. Th
Minimum vertical distance that a pilot can be from an airspace
without triggering an airspace warning. If this threshold is passed
a warning is emitted (event).
Ref. altitude
The Ref. Altitude parameter allows the user to dene the altitude
that is used to evaluate the airspace's proximity. The parameter
can be set to:
GPS Altitude - Altitude given by the GPS;
Altitude - Barometric altitude;
Flight Level - Barometric altitude expressed in hundreds
of feet and computed assuming an International standard
sea-level pressure datum of 1013.25 hPa (QNH).
Enable
If this parameter is set to YES, when a pilot is inside an airspace
area (as shown in a 2D representation, but not necessarily inside
the airspace), the airspace is drawn in Black. In this case all other
airspaces are drawn in Grey.
