In the radar view, Flarm objects are displayed with different shapes according to the information they contain:
Scale: Pressing the zoom button toggles through three different scales (0.5, 1.0, 6.0 Km), displayed in the upper left corner. List: Pressing the list button opens a new window with a list of all the just-received Flarm contacts. Time: Pressing the time button toggles the refresh interval of the radar view through 1, 2 and 3 seconds. Default is 2 seconds. The refresh rate also has an influence on the processor load and the object selection. Aliases: Pressing the monkey button opens a new window with a table of your defined Flarm alias names. Close: Pressing the cancel button (red with white X) returns to the map view.
Objects are drawn in different colours according to their assigned alarm level, or to indicate selection. The colours used are:
Square: If no track information is available, the Flarm object is drawn as a square. The square is also used to indicate a ground obstacle contained in your Flarm's database. Arrowhead: If track information is available, the Flarm object is drawn as an arrowhead pointing in the direction of movement.
Black: The alarm level of the object is low. This includes both the "no alarm" and "low-level alarm" levels described in the Flarm Dataport Manual. Orange: The alarm level of the object is important. This means that there is less than 13 seconds to go to a predicted collision. Red: The alarm level of the object is urgent, i.e., less than 8 seconds to a predicted collision. Magenta: The object has been selected by the user. In this case the alarm level of the object is not considered.
Note! The Flarm Operating Manual v4.06 uses different (English) terms for the above-mentioned alarm levels.
If you tap on a Flarm object in the radar view, you will get additional information displayed, if available. The information, drawn in magenta, is as follows:
Flarm identifier: The identifier of the selected Flarm object is displayed in the lower left corner as a 6-digit hex value. If an alias name has been defined for the Flarm identifier, this name replaces it. Distance: The distance to the selected Flarm object is displayed in the lower right corner of the window. Vertical separation and climb rate: The vertical separation and the climb rate of the selected Flarm object are displayed in the upper right corner of the window.
Any entry in the list can be selected by tapping on it. If you then press the Select button, the window is closed and you will return to the radar view. The additional data of your selected entry are now displayed there. A selection can be reset by pressing the Unselect button followed by the Close button.
Flarm identifier: The identifier of the Flarm object as 6-digit hex value. If an alias name has been defined for the Flarm identifier, this name replaces it. Distance: The distance of the Flarm object from one's own position. Vertical separation: The vertical separation of the Flarm object above (positive value) or below (negative value) one's own position. Relative bearing: The relative bearing to the Flarm object as an arrowhead. Ground speed: The ground speed of the Flarm object. Rate of climb: The rate of climb of the Flarm object. Can be positive or negative.
Leave the window with the Ok button to store the changes you made, or with the Cancel button to discard all changes.
If you select a row in the table and leave the window with the Ok button, the selected Flarm object will become your new selection in the map and radar views. To make a deselection of a selected object in the radar view, go into the alias window, do not select anything and return via Ok to the radar view.
The file format of the Flarm alias list is very simple. A comment line starts with a hash mark or a dollar sign in the leftmost position and ends with a new line. A valid entry has the following format:
<Flarm-Id> '=' <Alias-Name>Note that no white spaces are allowed on either side of the equals sign!Example:
# Flarm alias file, comment line $ another comment line ABCDEF=My best friend
In order to reduce the processor load, the data in the Flarm list views are only updated every three seconds.
