Settings - Airspaces

Airspaces
Airspace Table
The table shows you which kind of airspaces can be drawn on the map. Mark the boxes of the airspaces you want displayed. To change the colour of the airspace border or the airspace area, touch on the related field in the table. This will open a colour dialog. Pressing the Color Defaults button will assign the programmed default colours to all the airspaces.

Install Airspace
The Install Airspace button opens a new dialog box, in which you can define a proxy (by pressing the Set Proxy button) if you need one for Internet access. In the box labeled Airspace Url you can enter a url pointing to an airspace file. The url must consist of the following items:

  1. Scheme, such as http
  2. Hostname
  3. Pathname

If one of these is missing, the url is rejected. Furthermore, the file to be downloaded must be a normal file, not compressed, and must carry the extension .txt to enable it to be read in after download.

Airspace Warnings
You will get an optical and acoustical warning if you are near, very near or inside the specified airspace If you press the button Airspace Warnings you can set the lateral and vertical distances (separately for above and below) that will be applied when generating warnings. If the distance to an airspace is smaller than the specified values, the position is considered near or very near to the airspace.

The units used for the vertical and horizontal proximity distances can be configured on the Setting/Units page.
The display duration of warnings and their suppression for a certain time can be configured on Settings/Information page.

Note that Cumulus will only warn you for airspaces that are drawn unless you have activated the check box Draw all airspaces ... above me.

Airspace Filling
The Airspace filling button enables you to switch on or off the changing of the airspace fill colour according to the glider's proximity. As you get closer to the airspace vertically or horizontally, the transparency of the airspace fill colour changes, the percentage amount of change being set by the table according to whether you are near, very near or inside the airspace in question. If you disable the airspace filling, a fixed pattern is used for filling.
