V3 "ADS-B Version 3 Data" definition Information transmitted by aircraft equipped with an ADS-B Version 3 System (See Note 1) as defined in EUROCAE/RTCA documents ED-102B/DO-260C [ref. 5/6]. The ASTERIX implementation of this data has been defined in the Category 021 Specification Edition 2.6 (or later) and the Category 021 Reserved Expansion Field Edition 1.5 (or later). compound PS3 "Priority Status for Version 3 ADS-B Systems" group EP "Priority Status for Version 3 ADS-B Systems Populated" element 1 table 0: PS3 Element not populated 1: PS3 Element populated VAL "Priority Status for Version 3 ADS-B Systems" element 3 table 0: No emergency / not reported 1: General emergency 2: UAS/RPAS - Lost link 3: Minimum fuel 4: No communications 5: Unlawful interference 6: Aircraft in Distress Automatic Activation 7: Aircraft in Distress Manual Activation spare 4 remark Notes: 1. The ADS-B Version Number is contained in Data Item I062/380/SF#11/VN. 2. Since in this edition of the REF I062/REF/PS3 is the only Element in this Item, the Element Populated Bit strictly would not be necessary. However, if in a future edition use is made of the Spare Bits, the Element Populated Bit becomes important. 3. For ADS-B Version 3 systems as defined in ED-102B/DO-260C (Ref. [5], as defined in the core Specification of Category 062), the values have been re-defined. I062/REF/PS3 is to be used exclusively for Version 3 ADS-B systems as defined in I062/380/SF#11/VN. For ADS-B systems with a version number below 3, the PS shall be encoded in Data Item I062/380/SF#11/STAT. However, since values have been re-defined in ADS-B Version 3, mapping is required to ensure that information is not lost in systems not yet capable to decode this Edition of Category 062. This mapping shall be done according to the following table: :: ADS-B Version 3 (PS3) ADS-Version < 3 (I062/380 - STAT) 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) AS "Aircraft Status" group RCE "Reduced Capability Equipment" group EP "Element Populated Bit" element 1 table 0: Element not populated 1: Element populated VAL "Value" element 2 table 0: Not RCE 1: TABS 2: Reserved for future use 3: Other RCE RRL "Reply Rate Limiting" group EP "Element Populated Bit" element 1 table 0: Element not populated 1: Element populated VAL "Value" element 1 table 0: Reply Rate Limiting is not active 1: Reply Rate Limiting is active TPW "Transmit Power" group EP "Element Populated Bit" element 1 table 0: Element not populated 1: Element populated VAL "Value" element 2 table 0: Unavailable, Unknown, or less than 70 W 1: 70 W 2: 125 W 3: 200 W TSI "Transponder Side Indication" group EP "Element Populated Bit" element 1 table 0: Element not populated 1: Element populated VAL "Value" element 2 table 0: Unknown 1: Transponder #1 (left/pilot side or single) 2: Transponder #2 (right/co-pilot side) 3: Transponder #3 (auxiliary or Back-up) TAO "Transponder Antenna Offset" group EP "Element Populated Bit" element 1 table 0: Element not populated 1: Element populated RE "Range Exceeded" element 1 table 0: Value in defined range 1: Value exceeds defined range VAL "Value" element 6 raw spare 5 remark Notes: 1. TABS is the “Traffic Awareness Beacon System” as defined by ETSO-C199 / TSO-C199. 2. PW contains the nearest minimum transmit power (in Watts) at the antenna port. The nearest minimum setting in this field would be rounded down from the actual design value. For example, if the avionics is designed to transmit at 100W out of the antenna port, the encoded value in this field would be for 70W (decimal 1). 3. Bit-12 shall be set to 1 when the aircraft transmits the maximum encodable value (i.e. 31 representing a TAO greater than 58m). In this case TAO#VAL shall be set to the maximum encodable TAO (i.e. 58m). 4. The TAO is measured along the longitudinal axis of the aircraft from the forward end.
