Notes:

  1. Track type and coasting can also be derived from I062/290 System Track Update Ages
  2. If the system supports the technology, default value (0) means that the technology was used to produce the report
  3. If the system does not support the technology, default value is meaningless.
  4. Bits (EMS): other than subfield #11 of data item I062/380, these bits allow the SDPS to set the emergency indication as derived from other sources than ADS-B (e.g. based on the Mode 3/A code).
  5. Bit (PFT): with this flag an SDPS can indicate that internal processing points to the track being potentially false. Details on the internal processing are system dependent.
  6. Bit (FPLT): this bit - if set - indicates that the information contained in the target report has been updated by flight plan related data because no surveillance data was available for the target, or was created based on flight plan related data in areas with no surveillance.
  7. Bit (DUPT) is set to 1 if the correlation between the target report and a flight plan is not possible because the Mode 3/A code stated in the flight plan exists more than once in the surveillance data.
  8. Bit (DUPF) - if set to 1 - indicates that for a specific surveillance target more than one flight plan exists which makes correlation impossible.
  9. Bit (DUPM) is set to 1 if a target was correlated manually but also a regular flight plan exists.
  10. All tracks for which bits DUPT, DUPF or DUPM are set to 1 are marked on the CWP.
