  1. EGOA Enhanced General aviation Operations by ADS-B

  2. Introduction – General Aviation The general Aviation community, if considered to be mainly non commercial operations, is sometimes the one’s that need technical improvements and additional tools for their continued presences in the more and more regulated airspace of Europe the most. However, the costs attached to the various technologies developed for large commercial operations can hardly ever be justified. Overshadowed by commercial industry GA requirements need to be addressed

  3. General Aviation meaning… Aerial work Helicopters/ SAR Non commercial Gliders x-perimental Pipers/ Cessnas Twins.. Commuters According to Eurocontrol 8,33 Vertical expansion(ver:0.8) studythis group represents more than 90 000 Aircraft in Europe.

  4. Identified requirements • Continued/ improved presence of GA in controlled airspace – co-existence with larger commercial A/C • No use of safety-critical ASAS applications in cockpit for GA acceptable • “ADS-B out “ only - unless for information • GA not the driver in Europe…? • Min cost of equipment important • Minimum power important • Replacement of ELT • Avoidance of SSR Transponder for certain categories of aircraft like gliders • Mandatory air/ ground data link equipage not questionable for GA

  5. European planning RNAV GNSS (EGNOS/ Galileo ) Proposed mandate for air/ ground data link services Mode-S mandate to support TCAS/ACAS 8,33 KHz Vertical expansion ADS-B implementation

  12. User perspective • Surveillance • Support ADS-B out operations • Full access to controlled airspace • Safety/ follow up • Co-existence with commercial traffic • Emergency locator • Potential complement/ replacement to Mode-S • Voice • Embedded 8,33 capability for future expansion • Data communications • Access to basic services(ATIS, NOTAMS) • Broadcast information(AIS) • Navigation • Embedded GNSS receiver with EGNOS->Galileo capability • Differential GNSS support Single investment

  13. Previous test and analysis GPS VHF VDL Mode 4 radio Battery Picture showing an ADS-B equipped DG505 glider. Early test in 2000 to evaluate power, range, installations and user feedback.

  14. Summary • VHF Multi mode radio concept available • Potential synergies for the GA market identifed • GA organisations involved in the development • Concept needs to be discussed in a wider forum • Need to involve various programmes in Europe focusing on the individual elements of C,N and S. • Validation and test environment available • Certification and safety issue needs to be further analysed • Business case needed to verify the potentialbenefits.

  15. Existing trials environment Enhanced Operations for General Aviation –EGOA • 50 General Aviation A/C in dense TMA operations with focus on surveillance improvements with embedded navigation and communications elements. • Combined use of voice com and data com • Aircraft types ranging from gliders to twin engine • Can be expanded to adress 8.33, and GNSS/ EGNOS use. • Trials period Q1 2004 –Q1 2005.

  16. The EGOA project • SCAA project • Flying Clubs / Pilots • Air Traffic Controllers • Industry

  17. Objectives • To demonstrate and evaluate ADS-B for general aviation and other non-commercial aircraft including military • Following aspects will be considered: • - improved safety • improved efficiency for ATC • enhanced service to the users • enhanced availability to controlled airspace

  18. Goals • General aviation requirements in focus • Evaluation testbed, technique and operations • Information, acceptance and education to relevant organisations and partners.

  19. Goals… • Co-ordination with military sector • Preparation for certification/operational approval

  20. How? Through large scale operative trials/ demonstrations in Östgöta TMA, where numerous types of aircraft are involved, the operational scenarios will be presented and evaluated

  21. How… • Combined voice/ADS-B transonder • Presentation units integrated with ADS-B functionalities will be used – air/ground • Usage of approved standards and protocol • Development of rules and methods • Preparation for operational approval will be a parallel activity, FHA…

  23. Operative trial – Östgöta TMA • Moderate traffic at present, some increase is expected • Accessibility to terminal control (ÖKC) , operative and technical personnel • Appropriate equipment (Displays with ADS-B Functionality) • Reference system (MSSR) available • Supportive Flightclubs

  24. Step I • Automatic position reports • Certification of VHF Multi mode radio • Installation in 10 aircraft • Upgrade of ATC display with ADS-B functionality • Identification of measurable scenarios • Realisation with clear focus on safety aspects • Ground Focus • Rapports

  25. Step II • Installation of VHF Multi mode radio in 30 more aircraft • ”Situation Awareness” • Development and installation analyse of CDTI • Installation of CDTI i selected aircraft • Ground/Air Focus • Identification of large scale scenarios • Report/Evaluation -Pilot/Controller/Technical expertise

  26. Step III • Weather Applications (FIS-B) • VDLM4-Equipment for weather service • Upgrade of CDTI with weather interface • Development of weather server (prototype), operating with real weather information, METAR… • ATGround/Air Focus • Identification of appropriate scenarios, for trial activity • Report/Evaluation-Pilot/Controller/Technical Expertise

  27. Operative gains • Safety • Possibility to monitor ADS-B equipped a/c at own airport • Possibility to monitor ADS-B equipped a/c at neighbour airport • Positive identifying of airborne a/c, when equipped • Reduced risk for prohibited flying in controlled airspace • Relations/goodwill • Good relations to users , who will get access to controlled airspace thanks to ADS-B equipment • Workload • Reduced workload for ATC
