2. Introduction
CNS/ATM technology for oceanic and remote airspaces is very advanced but not in widespread use
Many Airlines who invested in FANS-1/A capabilities have yet to see promised benefits largely because capable ground systems are not in place
The FAA’s Advanced Technologies and Operational Procedures(ATOP) Program will bring advanced CNS/ATM infrastructure to US controlled oceanic airspace and deliver FANS-1/A benefits, especially in the Pacific
Adacel’s Aurora CNS/ATM system will`provide the oceanic automation for ATOP

3. Introduction - ATOP Program
Prime contractor is Lockheed Martin Transportation and Security Solutions (LMTSS)
Adacel is customizing its Aurora system software (the New Zealand OCS) to meet FAA requirements
Adacel’s Aurora software provides FDP, conflict probe, display processing, ADS-A, CPDLC, AIDC, etc.
LMTSS Micro-EARTS provides Radar and ADS-B
Airways New Zealand provides training and procedures

5. Delivering FANS-1/A Benefits

6. Drivers for ATM Automation
CUSTOMERS
The airlines are looking for the benefits of investing in FANS-1/A datalink technology.
ATS providers have identified that while freeing up controllers to focus on meeting customer requirements is very important, safety is paramount.
Automation can assume the function of identifying conflicts and free the controller to focus on solving them in a way that optimises service to the customer.

7. Drivers for ATM Automation
TRAFFIC VOLUMES AND MIX
Air traffic had been growing constantly over the last 10 years.
Separation standards are dependent on the CNS capability of the aircraft.
ATS providers recognised that the ATM system would need to be able to process a variety of aircraft capabilities and separation standards.

8. Drivers for ATM Automation
VISION
Progressive ATS providers share the airline vision that traditional procedural control and technology would be superseded, driven by customer requirements:
Cost reduction,
User Preferred Routes (UPR) and Dynamic Airborne Re-route Planning (DARP),
Avoidance of delays,
Responsive service orientated ATS providers.

9. ATM System Objectives
More Efficient ATM Service: reduced separation minima, provide preferred routes and levels(including flex tracks and dynamic reroutes), improve data communications with CPDLC and AIDC
Increased Controller Productivity: situation display to improve visualization of traffic, automated tools to increase speed and accuracy of separation calculations
Highest Level of Safety: minimize manual tasks, automate conflict detection, flight plan conformance monitoring

10. Operational Capability
User Preferred Tracks with Multiple Re-routes
Situation Awareness
Automatic Conflict Notification and Reporting
Clearance Issuing
Automatic Flight Plan Management
“Flight Plan” Coordination
Position reporting (radar, ADS-B, ADS-A, AIREPs etc)
Adaptable

11. Situation Awareness - ASD
Principle means for Air Traffic Controller to maintain situation awareness, supplemented by Flight Strip and Message Queue Windows.

12. Situation Awareness - FSW

13. Automatic Conflict Probe
A conflict probe is conducted
On receipt of a position report
(Radar, ADS or pilot position report)
Prior to issuing a clearance
Prior to accepting coordination
Automatically applies the appropriate separation standard
Separation standard is dependent on aircraft navigation capabilities, position report source and airspace volumes

23. ATM System Summary Many ATM systems provide controllers with:
CPDLC, ADS and AIDC,
Tools to apply separation standards,
And a whole lot of other features.
But these tools are inadequate on their own to meet the vision of the airlines for flight optimization and safety. Automated conflict prediction and reporting capability is required to fully deliver FANS-1/A benefits

24. FANS-1/A Benefits
Automation enables ATS providers to safely offer their customers
User preferred routes (UPR) and flight levels
Dynamic airborne re-routes (DARP)
Reduced separations

25. FANS-1/A Benefits Qantas Airways
Los Angeles
Fixed Track
UPR / DARP Savings ~ 25mins
This diagram demonstrates the Phases used in the South Pacific.
Describe.
Overall flight time savings averaging 25 minutes have been achieved. This is a huge benefit to airlines - especially when the flights are up to fifteen hours long and payload limited.
The savings are even more significant because QANTAS fly across the Pacific 30 times per week.
Specifically, the benefits are:
no more refuelling diversions en-route,
greater payload can be carried,
reduced fuel and operating costs,
increased city pair flying, and
improved safety due to the improved accuracy, reliability and integrity of the avionics.
This quite simply results in happier passengers and airlines.

26. Conclusion
System enables controller to provide continual separation assurance and deliver better service
Provides maximum benefits to FANS-1/A equipped aircraft while not penalizing non-equipped aircraft
Fulfills promise of fully utilizing airline investments in FANS-1/A
