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 6/4 (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. Bits 6/4 (EMS): if EMS is populated from ADS-B information the following shall apply: In ADS-B Version 3 (as defined in I021/210/VN) some values of EMS have been redefined. In order to provide the information also in Data Item I062/080/EMS, mapping is required to ensure that information is not lost in systems not yet capable to decode this Edition of Category 062. If I021/210/VN = 3, the values contained in I062/REF/PS3 shall be mapped to I062/380/EMS in line with the following table: :: ADS-B Version 3 (I062/REF/PS3) ADS-B Version < 3 (I062/080/EMS) 0 (No Emergency/not reported) 0 (No emergency/not reported) 1 (General emergency) 1 (General emergency) 2 (UAS/RPAS Lost Link) 4 (No communication) 3 (Minimum fuel) 3 (Minimum fuel) 4 (No communication) 4 (No communication) 5 (Unlawful interference) 5 (Unlawful interference) 6 (Aircraft in distress - 1 (General emergency) automatic activation) 7 (Aircraft in distress - 1 (General emergency) manual activation) 6. Bit 3 (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. In order to improve security on targets provided by ADS-B numerous validation functions have been developed in the ADS-B ground domain. If any of these validation functions show a potentially spoofed target, the PFT bit will be used to convey this information to the CWP. If and how this information is processed and displayed on the CWP is a local matter and not subject to the category 062 specification. 7. Bit 2 (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. 8. Bit 8 (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. 9. Bit 7 (DUPF) - if set to 1 - indicates that for a specific surveillance target more than one flight plan exists which makes correlation impossible. 10. Bit 6 (DUPM) is set to 1 if a target was correlated manually but also a regular flight plan exists. 11. All tracks for which bits 8, 7 or 6 are set to 1 are marked on the CWP. 12. Bit 5 (SFC) is set to 1 when the SDPS considers the target to be on the Surface (the actual meaning is implementation dependent – please refer to chapter 4.8 above). 13. Bit 4 (IDD) is set to 1 when the Flight ID is present more than once in the surveillance area. 14. Bit 3 (IEC) is set to 1 when the comparison between various sources has revealed an inconsistency in the information contained about emergency codes. 15. If I062/080 (MRH) indicates "Barometric altitude (Mode C) more reliable", and a calculated altitude is transmitted, it shall be transmitted using data item I062/135 “Calculated Track Barometric Altitude”. 16. If I062/080 (MRH) indicates "Geometric altitude more reliable", and a calculated altitude is transmitted, it shall be transmitted using data item I062/130 “Calculated Track Geometric Altitude”. In this case the source for I062/130 is indicated by I062/080 (SRC). 17. Data Items I062/130, I062/135, and I062/136 may be transmitted in parallel whenever the respective information is available. This is independent from the value transmitted on I062/080 (MRH). 100 "Calculated Track Position (Cartesian)" definition Calculated position in Cartesian co-ordinates with a resolution of 0.5m, in two's complement form. group X "X Coordinate" element 24 signed quantity 1/2 "m" Y "Y Coordinate" element 24 signed quantity 1/2 "m" 105 "Calculated Position In WGS-84 Co-ordinates" definition Calculated Position in WGS-84 Co-ordinates with a resolution of :math:`180/2^{25}` degrees. group LAT "Latitude" element 32 signed quantity 180/2^25 "°" >= -90 <= 90 LON "Longitude" element 32 signed quantity 180/2^25 "°" >= -180 < 180 remark Notes: - The LSB provides a resolution at least better than 0.6m. 110 "Mode 5 Data Reports and Extended Mode 1 Code" definition Mode 5 Data reports and Extended Mode 1 Code. compound SUM "Mode 5 Summary" group M5 "" element 1 table 0: No Mode 5 interrogation 1: Mode 5 interrogation ID "" element 1 table 0: No authenticated Mode 5 ID reply 1: Authenticated Mode 5 ID reply DA "" element 1 table 0: No authenticated Mode 5 Data reply or Report 1: Authenticated Mode 5 Data reply or Report (i.e any valid Mode 5 reply type other than ID) M1 "" element 1 table 0: Mode 1 code not present or not from Mode 5 reply 1: Mode 1 code from Mode 5 reply M2 "" element 1 table 0: Mode 2 code not present or not from Mode 5 reply 1: Mode 2 code from Mode 5 reply M3 "" element 1 table 0: Mode 3 code not present or not from Mode 5 reply 1: Mode 3 code from Mode 5 reply MC "" element 1 table 0: Mode C altitude code not present or not from Mode 5 reply 1: Mode C altitude from Mode 5 reply X "X-pulse from Mode 5 Data Reply or Report" element 1 table 0: X-pulse set to zero or no authenticated Data reply or Report received 1: X-pulse set to one PMN "Mode 5 PIN/ National Origin/Mission Code" group spare 2 PIN "PIN Code" element 14 raw spare 3 NAT "National Origin" element 5 raw spare 2 MIS "Mission Code" element 6 raw POS "Mode 5 Reported Position" group LAT "Latitude" element 24 signed quantity 180/2^23 "°" >= -90 <= 90 LON "Longitude" element 24 signed quantity 180/2^23 "°" >= -180 < 180 GA "Mode 5 GNSS-derived Altitude" group spare 1 RES "Resolution with which the GNSS-derived Altitude (GA) is Reported" element 1 table 0: GA reported in 100 ft increments 1: GA reported in 25 ft increments GA "GNSS-derived Altitude of Target, Expressed as Height Above WGS 84 Ellipsoid" element 14 signed quantity 25 "ft" >= -1000 EM1 "Extended Mode 1 Code in Octal Representation" group spare 4 EM1 "Extended Mode 1 Reply in Octal Representation" element 12 string octal TOS "Time Offset for POS and GA" description Time Offset coded as a twos complement number with an LSB of 1/128 s.
