Horizontal Bearings
Twelve 2-colour LED illustrate the rose of the compass – “Above” conforms to the actual flight direction. Each
LED entails an identically large horizontal section of 30°.
During warnings with FLARM
TM
either 1, 2 or 3 LED’s flash depending on the threat level, the external display
V3+ always shows only one LED.
Recently it is possible to show the warnings on the V3+ analog to the FLARM
TM
indicators. Information to
enable this function “Compatibility Mode” is found in the chart “Configuration”.
Relevant direction is shown as the center of the illuminated LED’s.
Threat levels:
Moderate threat (less than approximately 19 – 25 s until possible collision)
-> red LED & buzzer interval slow (~ 2 Hz)
Severe threat (less than approximately 14 – 18 s until possible collision)
-> red LED & buzzer interval middle (~ 4 Hz)
Immediate threat (less than approximately 6 – 8 s until possible collision)
-> red LED & buzzer interval rapid (~ 6 Hz)

Vertical Bearings
The vertical bearing to another airplane operates relative to own flight altitude – independent of own position
– and is indicated on the vertical LED’s.
The indication is not determined by the absolute altitude difference but considers the distance as follows:
(1) no LED illuminated, by a vertical bearing angle less than 7°
(2) inner LED’s illuminated by a vertical bearing angle of 7 to 14°
(3) outer LED’s illuminated by a vertical bearing angle more than 14°
The flashing frequency is the same and synchronous to horizontal indicators.
