Keith McPherson
Manager GNSS

2. ICAO Document “A32-19: Charter on the Rights and Obligations of States Relating to GNSS Services”
……….
2. Every State and aircraft of all States shall have access, on a non-discriminatory basis under uniform conditions, to the use of GNSS services, including regional augmentation systems for aeronautical use within the area of coverage of such systems.
4. Every State providing GNSS services, including signals, or under whose jurisdiction such services are provided, shall ensure the continuity, availability, integrity, accuracy and reliability of such services, including effective arrangements to minimize the operational impact of system malfunctions or failure, and to achieve expeditious service recovery.

13. 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

14. 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 will all gave GBAS Cat-1 as standard avionics fitment

16. Australian Augmentation Experience
LAAS SCAT-1 Melbourne Airport (Honeywell SLS-2000)
LAAS SCAT-1 Canberra Airport (Raytheon DIAS-3100)
LAAS SCAT-1 Avalon Airport (Honeywell SLS-2000)
LAAS SCAT-1 Norfolk Island (Honeywell SLS-2000)
GBAS CAT-1 Sydney Airport (Honeywell SLS-3000)

17. 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

18. 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 world’s 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. No single augmentation system provides a global answer –
Final Message:
No single augmentation system
provides a global answer –
There is a synergy between, and a need
for, all four ICAO augmentation systems

20. Thank you
