  1. Présenté par Patrick Souchu ADS-B Out Certification JAA CNS/ATM 21-22 juin 2005

  2. ADS-B out : Statement of issue • ADS-B out : Broadcast of identification, position, altitude, velocity, Navigation integrity data by the aircraft • 1090 ES technology • Used initially for radar-like surveillance service by ATC • Part of ADS-B Package 1 application : ADS-B NRA, ADS-B ACC, ADS-B TMA, ADS-B APT, ADS-B ADD • Ground stations are easy to install and much cheaper than radar • ADS-B separation standard under definition by ICAO SASP • 5 Nm separation already approved by Australia under specific conditions • Simple installation in the aircraft : transponder + GNSS receiver • Currently under implementation : Australia, US, France (La Réunion Island), CASCADE program in EUROCONTROL • Stream 1 : 2008-2011 • Mediterranean project

  3. ADS-B Installation • Many aircraft are already fitted with ADS-B capabilities • Many Mode S transponders for Enhanced surveillance are capable of ADS-B • No certification of ADS-B data, only non interference considerations • Guidance material is needed • Initial results from Toulouse validation trials • Excellent detection range (200 Nm, up to 250 Nm) • Various quality of aircraft installation • NUC = 0 often observed • Aberrant case observed • Eg NUC = 8 with impossible shift of transmitted position • Specific cases will be analysed case by case • Increasing number of equipped aircraft • Peak of 53 ADS-B aircraft at the same time detected by the ground station in Toulouse

  4. Proposed guidance material • Guidance for installation, certification and maintenance of ADS-B installation • ADS-B system compliant with ED102/DO260 as a minimum • Identification of the aircraft • Barometric altitude shall be provided and geometric altitude may be provided • Position shall be provided with quality indicators NUC or NIC/NAC/SIL • If NUC is provided, its value must correspond to HIL (Horizontal Integrity Limit) • GNSS capability required for separation purpose (NUC >= 5) • Receiver compliant with TSO C129 (FDE + continuous RAIM 0,3 Nm) or TSO C145/C146 • Periodic update interval of at least 1 s

  5. Conclusion • 1st draft produced for this meeting • It is urgent to clarify the airborne equipment situation • It is suggested to foster the delivery of this paper to EASA • Comments are expected • Finalisation of this paper at next meeting
