  1. The CASCADE Programme JAA CNS/ATM Steering Group 31 January 2007 Alex Wandels & Jörg Steinleitner CASCADE Programme EUROCONTROL European Organisation for the Safety of Air Navigation

  2. Content ADS-B Context NPA

  3. Initial Operational Capability • Ground Surveillance Applications (ADS-B-out) 2008 ADS-B Receiver • Airborne Surveillance Applications (ADS-B-in & TIS-B) 2011

  4. ADS-B Policy “Deployment based on local operational requirement” We expect: • ADS-B-out • ADS-B-NRA (TMA) • ADS-B-RAD • ADS-B-in • ATSAW (VSA-ITP) A mandate is a possibility.

  5. ADS-B-NRA Trials 13 ANSPs 200 aircraft 280,000 flights/year

  6. Trials Efforts Converge Pioneer Phase Certified Aircraft OperationalApproval EASA AMC ED-126 GS Standard Safety Case Ground Stations Installed Readiness forOps Approval Operational Approval 2007 2009 2010 2008

  7. Content ADS-B Context NPA

  8. JAA “Position Paper 039” Status Draft NPA – ADS-B-NRA Advisory Material • “For the Approval of 1090 MHz ES ADS-B installation in support of theADS-B-NRA Application” • Aircraft operator airworthiness and operational approval • ED-126  aircraft installation and operation requirements • Final draft for JAA CNS/ATM SG approval: NPA 039-7

  9. ADS-B-NRA SPR/INTEROP ADS-B-NRA Safety, Performance& Interoperability Requirements Published as international standard: EUROCAE ED-126 & RTCA DO-303 Basic NPA reference

  10. 1090ES “ADS-B out“Required Data Items TransponderControl Panel Callsign SPI-EI Position HPL HFOM (Velocity) (Time) Mode S Transponder BDS 0,5 BDS 0,8 (BDS 0.9) (BDS 6,1) (BDS 6,5) GPS Extended Squitter 24-bit address NUC-NIC/NAC FL Barometric Altimeter

  11. ADS-B-NRA Requirements (1/2) Integrity Containment 1NM (0,5NM) Accuracy (95% errors) 926m (528m) Time-to-alert: 10 sec Monitoring failure: 10-3 (overall alert failure: 10-7/h) • Horizontal Position – supporting 5NM (3NM) separation • System Integrity (data corruption) – 10-5/fh (“major”) • System Continuity – 2*10-4/fh (“minor”) • Baro Altitude, Aircraft Identification, SPI, Emergency Status, 24-bit address  as for Mode A/C/S

  12. ADS-B-NRA Requirements (2/2) *) TSO129 engines beware ! GPS engine ETSO129*/145/146 HPL HFOM accuracy integrity Latency: 1,5sec/95% NUC NIC NAC ED102/DO-260 DO-260A ED73B/DO-181C (ETSO-2C112b)

  13. NPA 039-7 Changes to NPA 039-6 (4 Sep ‘06) • Finalisation of ED-126 standard development • As already addressed at CNS/ATM SG #36 • Resolution of CNS/ATM SG #36 comments • Resolution of OST comments (as implemented by Maria) • Encoding of the NUC quality indicator (initial implementations) • Feedback CASCADE ADS-B Pioneer Project • Addition of clarifying note ADS-B-NRA service provision • Refinement AFM airworthiness compliance considerations      

  14. Initial Implementation “Waivers” Mitigation Means 7500,7600,7700 “emergency” NUC=6,7,8,… NUC=5 HPL HFOM NUC • Emergency Status: • Establishment of operational procedures (implies pilots & controllers training for use) • Consistent Accuracy Quality Indication: • Treating higher quality indicator encodings as requirements compliant lower one • NUC encoding on HPL only: • Rare frequency (and limited duration) of RAIM function unavailability (i.e. to calculate HPL) • Use of RAIM prediction (as for NAV GPS-NPA procedures)

  15. NPA 039-7 - Conclusions ED-126/DO-303 are published Incorporation of final OST comment resolution CASCADE ADS-B Pioneer Project feedback Improved language on applicant requirements Ground mitigations for initial deployment “waivers” Considered mature for JAA CNS/ATM SG approval
