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
Content ADS-B Context NPA
Initial Operational Capability • Ground Surveillance Applications (ADS-B-out) 2008 ADS-B Receiver • Airborne Surveillance Applications (ADS-B-in & TIS-B) 2011
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.
ADS-B-NRA Trials 13 ANSPs 200 aircraft 280,000 flights/year
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
Content ADS-B Context NPA
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
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

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
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)
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
