Problem Solving
By looking at the problem from a different
perspective, Australians could see the problems
and issues with other augmentation systems

GBAS Working Group Meeting 4

• Eurocontrol and FAA meeting
• Normally held in Europe and USA
• Held in Sydney in February 2006
• 76 delegates, 22 countries
• Aim is to harmonise GBAS Cat-1 in Europe and USA
• Airservices Australia now attending as it is
  taking the lead role in GBAS Cat-1 certification
  
• Next meeting in Brussels date TBA

Whats New in Sydney?

• Worlds first flight inspection of an ICAO GBAS
  Cat-1 signal in space for use by revenue earning
  aircraft, using a States accredited flight
  inspection aircraft
• Engineering Readiness Review completed
• Operational Readiness Review completed
• Procedures Designs finished in accordance with
  SARPs
  
• Worlds first revenue earning flights by Qantas
  in May
  
• All Qantas B-737-800 pilots trained and ready to
  go
  
• System is not certifiable as the software is not
  built
  
• to DO-178B or equivalent

Flight Inspection Results

Beta GBAS Cat-1 Sydney

• Phase 1
• Hazard Analysis completed
• Aircraft allowed to fly to Minimum Vectoring
  Altitude
  
• Allows pilots and controllers to settle into the
  new technology
  
• Further Phases
• Evaluate if we are happy to lower the minima
  with experience
  
• on a non certifiable system

ICAO Compliant GBAS Cat-I in Australia

• Airservices Australia has partnered with
  Honeywell International Inc to bring an ICAO
  compliant GBAS Cat-I to completion
  
• Started 10 April 2006
• Approximately 22 months to complete RTCA
  DO-178B/278 compliant software Approximately 6
  months of certification
  
• Regulator (Civil Aviation Safety Authority)
  involved from Day 1
  
• Aim is to have CASA approve Part 171 change to
  allow operation of completed system by mid 2008
  
• Technical Cooperation Agreement signed with the
  FAA to share information, staff and procedures

13
ICAO Compliant GBAS Cat-I in Australia

• Will build and certify to FAA Doc 2937A, which
  will qualify the systems as ICAO GBAS SARPs
  compliant
  
• FAA will issue Type Approval for the ground
  station only as a Non-Fed system
  
• Once Type Approval achieved, system migrates to
  Australia for the full certification program
  
• System will be built to enable elliptical or
  horizontal polarised broadcasts
  
• Certification involves ground station, site
  surveys, maintenance plans, logistics plans,
  flight inspection plans, pilot training, pilot
  licensing, ATC training

14
GRAS

• APV-I (0.999 availability) will be achieved in
  low density areas
  
• APV-I (0.9999 availability) will be achieved in
  high density areas
  
• APV-II was assessed and the benefit gained was
  considered not worth the additional investment
  
• USA found the same, that APV-II was a significant
  cost increase over APV-I for minimal benefit
  
• ICAO only requires APV-I

15
What we are trying to avoid
16
GRAS

• Phase 1 System Definition was completed in March
  2006
  
• Phase 2 commenced 10 April 2006
• ICAO Council approved GRAS SARPs in February 2006
  
  
• GRAS SARPs to be issued as Annex 10 Amendment 81
  on 23 November 2006

17
GRAS

• RTCA GRAS MOPS (Avionics) now in penultimate
  draft
  
• To commence Final Review and Comments (FRAC) mid
  year
  
• MOPS cater for high end aircraft, regional,
  charter and general aviation
  
• Queensland University of Technology PhD students
  are building a General Aviation aircraft GRAS
  receiver
  

18
GRAS CERTIFICATION

• 8 GRAS Reference Stations in Australia
• 4 GRAS VHF Stations in Far North Queensland
• Cairns and Cape York Peninsula
• 2 Master Control Stations
• Test in worst ionospheric conditions available in
  Australia
  
• Test in worst weather conditions - tropical rain
  storms
  
• Test continuity and maintenance in inaccessible
  areas, where repair teams can take 3 days to get
  to site.

2nd Last Message

• Airservices Australia and Honeywell are forging
  ahead with GBAS Cat-1 and GRAS development and
  certification
  
• The synergy between GBAS and GRAS avionics is so
  close that the combination provides a cost
  effective solution to augmentation
  

20

• Final Message
• No single augmentation system
• provides a global answer
• There is a synergy between, and a need
• for, all four ICAO augmentation systems
