FLARM #
Alarm Level #
[Disable] [Level 1] [Level 2] [Level 3]
The variometer display is of secondary importance when a collision is imminent. When a FLARM is connected, the device can therefore be used to implement an acoustic and optical FLARM warning, similar to the common LED FLARM secondary display with a higher level of detail and additional information. The default is [Level 1], the FLARM warning is switched on at level 1 and informs you from the lowest alarm level “1” of the FLARM in the event of an impending collision in 13 to 18 seconds, level 2 would warn at 9-12 seconds, corresponding to level 3 only from the highest alert level, i.e. the immediate danger of a collision, between 0 and 8 seconds. Please refer to the description of the FLARM used for further details.
The warning is given on its own screen, which graphically in the form of a red triangle informs about the direction from which the danger is coming, both in the top view and in the horizontal view. An example of a Traffic Alert Alert level 1, the lowest alert level, see right. The danger comes from the front slightly to the left, shown here is a relative bearing of -10 degrees, so the red triangle shows the exact angle, analogously to the horizontal view. Furthermore, the type of warning and the alarm level is output by means of text, e.g. with “Traffic Alert 2”. The direction of approach in the clockwise system, e.g. “2 o’clock”, the relative distance and the relative altitude difference in the selected unit system.
Alarm Volume #
[100 %]
The audible warning is designed as a constant and rapidly alternating two-tone tone to distinguish it from other tones and increases in frequency, tone sequence and volume according to the alarm level. In the highest alarm level 3, the warning tone is output with the level set here. At alarm level 2, the noise is reduced by around 6 decibels, at alarm level 1 by around 12 decibels. The default is 100%, the volume can be varied between 20% and 125%.
Alarm Timeout #
5 sec
Configure here the time FLARM alarm warning keeps displayed after the Flarm alarm went off. Default is 5 seconds, together with the time the alarm is present this is normally enough time to read the and interpret the display. For feature testing and other purposes a longer time might be appropriate, and in competition even a shorter time may make sense, e.g. when circling in a lift with many other gliders.
FLARM Simulation #
[Disable] [Start Sim]
The simulation of an approach by a second aircraft can be simulated under this menu item. The approach begins to the left below and moves to the right, with a further decrease in distance and height difference, past the bow. Different alarm levels of the FLARM are simulated optically and acoustically. The setup must be exited in order to be able to follow the situation on the screen.
