Current Status
GBAS Cat-I

• ICAO GBAS Cat-I SARPs already issued
• Approved ICAO compliant system in Australia (Part
  171 change) in 2008 at Sydney International
  Airport
• Strong support from international airlines
  Qantas, Lufthansa, Fedex, Continental Air
  Micronesia
• Sydney Beta GBAS Cat-I installation completed
  October 2005
• Sydney Beta GBAS Cat-I first broadcast 29
  October 2005
• DFS Germany has a beta GBAS Cat-I (Frankfurt,
  soon Bremen)
• AENA Spain has a beta GBAS Cat-I (Malaga)
• Memphis Tennessee has beta GBAS Cat-1
• Global reach of GBAS Cat-I is increasing

Goal - gate to gate precision navigational
service for aircraft

B-737NG GLS Certification Status

• Certification Flight Test
• Verification, validation complete
• Demonstrated at SeaTac Moses Lake using Beta
  LAAS
• Operations (including automatic landings)
  demonstrated at adjacent airports Ephrata,
  Boeing Field Paine Field
• Test airplane flown against FAA prototype ground
  station at Rio de Janeiro (Galeao) with
  approaches to adjacent airport (Santos Dumont)
• QANTAS
• - 9 B-737NG with GBAS Cat-1 avionics
• - 24 B-737s may be retrofitted with GBAS Cat-1
  avionics
• Boeing and Airbus plan to introduce GLS on all
  forward fit aircraft and retrofit where cost
  effective

15

• A-380 GLS Certification Status
• QANTAS will take delivery of 12 x A-380s with
  GBAS Cat-I avionics
• Other Airbus aircraft to be procured will be
  fitted with GBAS Cat-I avionics
• Boeing
• B-737NG, B-787, B-777 (New), B-747-8 will all
  gave GBAS Cat-1 as standard avionics fitment

ICAO Compliant GBAS Cat-I in Australia

• Airservices Australia negotiated with Honeywell
  International to bring an ICAO compliant GBAS
  Cat-I to completion
• Approximately 22 months to complete RTCA
  DO-178B/278 compliant software commenced 10
  April 2006
• Approximately 6 months of certification
• Civil Aviation Safety Authority involved from Day
  1
• Aim is to have CASA approve Part 171 change to
  allow operation of completed system by 3rd
  quarter 2008 or earlier
• Germany, Spain and USA offered to assist and
  those offers were accepted.
• GNSS Technical Memorandum of Cooperation signed
  with FAA 9 February 2006

2nd Last Message

• New aircraft are being fitted with GBAS Cat-I
  avionics
• B-737s will be retrofitted with GBAS Cat-I
  avionics
• Qantas has taken the lead internationally
• GBAS Cat-I is HERE and it is HERE to STAY
• 73 of the worlds airports are GBAS Cat-I (IATA
  study)
• GBAS Cat-I offers more than ILS
• Legacy aircraft will be around for a long time
  and SOME ILS will remain but not as many

19

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