RSP Specifications ADS-C OPA: Annex G • Different RSP Specs: • ENR-1/TMA/APT 1) • ENR-2 2) • 1)ENR-1/TMA/APT, Perf Spec labelled as ‘RSP’, despite reports • are used for ATCComm and 4DTBO • 2) No re-assessment of Perf Specs for ENR-2 • Requirements and Recommendations (Rec) • ‘Rec’ for ACSP, ATSU, Initiator, Recipient • GOLD format: • Perf Specs for ATSP, AO, AC System and ACSP (mainbody) • includes statements on means of compliance
Commonalities of RSP Specs Exponential Approach for timing Allocations (99.9% and 95%) Timings Specification Same ADS-C Generation Time Same Aircraft and ATSU system timings Availability Specification for ACSP, ATSU: Efficiency and Safety
Main Differences Timings for ACSP ENR-1/TMA/APT: short (as for CPDLC) ENR-2: long (satcom) • RSP Specification • ENR-1/TMA/APT: • Single/1stPeriodic/Baseline report • Next Periodic/Event report Needed? • ENR-2: • Next Periodic/Event report
RSP TRN Reaction TSD for ADS-C - Demand/Periodic/Event Contract AIRCRAFT ATSU ACSP Controller ATSU System Comm. service Aircraft System FMS (Initiator) Composition ADS-C Request (Demand/Periodic/Event) Generation ADS-C report RSTP Positive Ack Single/1st Periodic/ Baseline report Recognition (Initiator) Event/Periodic Timeout Generation ADS-C report Composition (Initiator) RSP Next Periodic/ Event Report RSTP=TRN Recognition (Recipient)
RSP Specification: ENR-1/TMA/APT • Based on 2Kbyte EPP report: • Basic data + 20 waypoints with EPP data RSP Specification: RSP120 for Single/1st Periodic/Baseline Time-out at 100 seconds for controller RSP95 for Next Periodic/Event Needed? See Annex G - G.5.1
RSP Specification: ENR-2 Based on existing docs: ED122 and GOLD v1.0 • RSP Specification: • For Next Periodic/Event only • RSP180 and RSP400 • Timing allocations differ from GOLD (now Expon approach) See Annex G - G.5.2
ENR-1/TMA/APT: RSP95 & RSP120 (1) ADS-C Generation GND Timer ADS-C Generation
ENR-2: RSP180 (‘78/214’) & RSP180 (GOLD-v1) ADS-C Generation
ENR-2: RSP400 (‘78/214’) & RSP400 (GOLD-v1) ADS-C Generation
ENR-2: RSP180/400 & RSP180/400 same in WG78/SC214 and GOLD-v1)
