Traffic received by PilotAware can be seen in real-time by accessing the Traffic page from the selection bar on any page. The Traffic Page will look something like this.

Whilst it is not necessary to understand this, it does give an insight into the technology
and the depth of information used by PilotAware.


PilotAware will highlight traffic within the table that could pose a threat.
This threat level is defined from the Configuration page field 'Select Audio Warning Zones'. This can be adjusted manually within the Configuration page.

🟢 = Alert

🟡 = Warning

🔴 = Danger

Column 1 Hex;

This shows the unique ICAO code that is being transmitted or the code assigned by a PilotAware Unit or FLARM unit. We encourage ALL EC users to transmit the correct ICAO code.

Column 2 Registration;

This is the Tail Registration (or ground station) for the assigned Hex Code.

Column 3 Modes CSAPFMU;

This column shows the detected transmission using the following codes.

  • C – Mode-C
  • CS – Mode-S
  • CSA – ADS-B / Extended Squitter
  • P – PilotAware
  • F – Flarm (direct) Reception
  • M – MLAT (via Uplink)
  • U – Data from Uplink

Any target received could involve multiple codes. For example, in the screenshot above:

  • Line 1 is ---P--U: This is an OGN-R station uplinked via PilotAware.
  • Line 2 is CS-P-MU: This is Mode-S detected directly with MLAT data being Uplinked via
    OGN-R, hence distance and bearing being available in columns 5 and 7.
  • Line 3 is CSA----: This is a straight ADSB reception. The 29,641 feet also gives this away.
  • Line 6 is CS------: This is a direct Mode-S reception with no associated MLAT. This is
    probably because it is further than 50Km away, hence no MLAT provided.
  • Line 13 ---P-MU: This is uplinked MLAT data via PilotAware. No action has been taken
    because there has been no direct reception of Mode-S.
  • Line 24 is C-------: This is a Mode-C target note no ICAO code tail registration, bearing or distance.

Column 4 SQ;

This column shows the Squawk code(Mode-A), and equivalent Mode-C Altitude image code
if appropriate.

Column 5 D(KM);

Distance from the host aircraft position. Only applicable to aircraft transmitting a location
such PilotAware, FLARM, ADSB and Mode-S/3D.

Column 6 A(ft);

Relative height difference in feet, of the target from the host position. A direct Mode-S
reception is required for this to be added to the MLAT data provided.

Column 7 BR;

Target bearing direction from the host position. Only applicable aircraft transmitting a GPS
signal such PilotAware, FLARM, ADSB and Mode-S targets provided with MLAT data.

Column 8 SIG;

Signal strength of received 1090MHz Targets (ADSB Mode-C and Mode-S)

Column 9 AGE;

Age of last received data from the target in seconds.

Column 10 ADSB Status In following order;

Version, NACp, SDA, NICa, SIL, SILs.

Column 11 Aircraft Owner;

Information regarding registered aircraft owner.
