Accident Near Mangalore Airport - Possibly 2 Aircraft down

[Hot and Hi]

FLARM is one of several available Personal Collision Avoidance Systems (PCAS).

FLARM is a proprietory position/ALT/speed transmitter and receiver, widely used in the glider community. If two aircraft have FLARM installed, they can both see each other. The FLARM receiver analyses the relative movements of other FLARM equipped targets and accordingly prioritises traffic alerts presented to the pilot.

A newer, and less expensive PCAS is PilotAware. While it too has its proprietary position/ALT/speed outgoing signal (which only other PilotAware users can read), the PilotAware receiver sees other aircraft equipped with ADS-B Out, TPX S, TPX C, FLARM or PilotAware. Similar to FLARM, it can display traffic in various ways (incl on TCAS-style traffic radar screens), filter and prioritise threats, and can also generate spoken, explicit traffic alerts.
