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 ones 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

According to Eurocontrol 8,33 Vertical
expansion(ver0.8) studythis group represents
more than 90 000 Aircraft in Europe.

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

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-gtGalileo
  capability
• Differential GNSS support

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 potential
  benefits.

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.

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
