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

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.
