## Presentation

- GBAS Working Group Meeting #4
- GBAS Sydney
- GBAS Cat-1 Certification
- GRAS

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

**Problem Solving**

## 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

## GNSS Operational Benefits

- Angled Approach

- Straight Approach

- Sectored Approach

- Parallel Approach

- Curved Approach

- Runways

- Terrain Restrictions

- Guided Departures

- Community Noise Concerns

- GRAS and GBAS provide
- Vertical Guidance and
- Flexible approaches

## World’s first flight inspection of an ICAO GBAS Cat-1 signal in space for use by revenue earning aircraft, using a State’s accredited flight inspection aircraft

Engineering Readiness Review completed
Operational Readiness Review completed
Procedures Designs finished in accordance with SARPs

World’s 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

**Flight Inspection Results**

## 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**

## 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

## 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

## What we are trying to avoid

## 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

## 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

## 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

## Final Message:

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

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