Fixed-Obstacle Warning
Many FLARM
TM
systems and compatible devices also include a fixed-obstacles database. Since February
2011 systems include approx. 35 000 coordinates of over 11,000 geographical obstacles in the Alpine
regions.
Check if mainframe to which the display is linked has such (actual) a database – only then can the external
display V3+ illustrate the appropriate traffic information and warnings.
When FLARM
TM
calculates the collision threat with the fixed-obstacle, the system will warn as follows:
simultaneous flashing of two LED’s,
flashing and buzzing rate depends on threat.
(same as “Aircraft Warning”)
Comment:
-> A fixed-obstacle is always in the moving direction; there is no specific direction indication.
-> There is no vertical position indication.
-> There is a warning given when the aircraft flies underneath power transmission lines and cable car wiring.
-> The indicator updates every second.
Indicator “Mute-mode”
Independent from the actual operation mode a temporary indicator and buzzer mute-mode can be chosen:
After a double click FLARM suppresses for a 5-minute period all visual and acoustic traffic, fixed-obstacle
and threat information.
The suppression is confirmed with a decreasing sound sequence. With an additional double click this
suppression- function is immediately terminated and reconfirmed by an increasing sound sequence.
The Mute-mode can interrupt frequent alarming by thermal circling with several aircraft – but can no longer
give a warning in the case of the actual threat!
For safety reasons the Mute-mode is automatically canceled after the 5-minute period – this is confirmed by
the increasing sound sequence.
