c) Enhanced bit and confidence declaration techniques applied to the airborne receiver classes as shown below: Annex 10 — Aeronautical Telecommunications Volume IV 22/11/07 5-4 1) Class A1 – Performance equivalent to or better than the use of the “Centre Amplitude” technique. 2) Class A2 – Performance equivalent to or better than the use of the “Multiple Amplitude Samples” baseline technique, where at least 8 samples are taken for each Mode S bit position and are used in the decision process. 3) Class A3 – Performance equivalent to or better than the use of the “Multiple Amplitude Samples” baseline technique, where at least 10 samples are taken for each Mode S bit position and are used in the decision process. Note 1.— The above enhanced reception techniques are as defined in RTCA DO-260A, Appendix I. Note 2.— The performance provided for each of the above enhanced reception techniques when used in a high fruit environment (i.e. with multiple overlapping Mode A/C fruit) is expected to be at least equivalent to that provided by the use of the techniques described in RTCA DO-260A, Appendix I. Note 3.— It is considered appropriate for ground extended squitter receiving systems to employ the enhanced reception techniques equivalent to those specified for airborne Class A2 or A3 receiving systems. 5.2.3 Report assembler function 5.2.3.1 The report assembler function shall include the message decoding, report assembly, and output interface sub-functions. 5.2.3.2 When an extended squitter message is received, the message shall be decoded and the applicable ADS-B report(s) of the types defined in 5.2.3.3 shall be generated within 0.5 seconds. Note 1.— Two configurations of extended squitter airborne receiving systems, which include the reception portion of the ADS-B message exchange function and the ADS-B/TIS-B report assembly function, are allowed:
