  3. NextGen Key Concepts • Satellite Based navigation • ADS-B • In / Out • Performance Based Navigation • RNP/RNAV • TBO • Data Link Communications • Internet • SWIM • Net Centric • 4D Weather

  4. Automatic Dependent Surveillance Broadcast (ADS-B) - Initial Operations • (ADS-B) uses the U.S. NAVSTAR GPS to broadcast the position and intent of the aircraft. It then automatically transmits this information — with more precision than radar — to air traffic managers and pilots. Through more accurate surveillance, ADS-B will allow for more efficient separation of planes. In the cockpit, pilots also will have access to information on weather, traffic and flight restrictions. • Since the late 1990s, aircraft equipped with ADS-B technology have been participating in an FAA test program in southeastern Alaska called Capstone. In preliminary estimates, accident rates for both general aviation and commercial carriers participating in Capstone have dropped 40 percent when compared to aircraft operating elsewhere in Alaska. Delivery company UPS is also currently using ADS-B technology. This has allowed UPS to save millions of dollars in jet fuel, reduce emissions by 34 percent and noise by 30 percent at its hub airport in Louisville, Kentucky. • ADS-B will next be deployed at key sites in the U.S. by 2010, including the Gulf of Mexico, Louisville, Juneau and Philadelphia. The nationwide infrastructure will be rolled out by around 2013. Aircraft will be required to be equipped with ADS-B Out by 2020. • Major milestones • In service decision for broadcast services (Traffic Information Service – Broadcast and Flight Information Service Broadcast), November 2008 • Louisville Initial Operating Capability of Surveillance Services, October 2009 • Gulf of Mexico Initial Operating Capability of Surveillance Services, December 2009 • Philadelphia Initial Operating Capability of Surveillance Services, February 2010 • Juneau Initial Operating Capability of Surveillance Services, April 2010

  5. Airborne ADS-B NextGen Base Technology Surface

  6. ADS-B Benefits • Provides air-to-air surveillance capability. • Provides surveillance to remote or inhospitable areas that do not currently have coverage with radar. • Provides real-time traffic and aeronautical information in the cockpit. • Allows for reduced separation and greater predictability in departure and arrival times. • Supports common separation standards, both horizontal and vertical, for all classes of airspace. • Improves ability of airlines to manage traffic and aircraft fleets. • Improves ability of air traffic controllers to plan arrivals and departures far in advance. • Reduces the cost of the infrastructure needed to operate the National Airspace System

  8. Performance Based Navigation • RNP / RNAV • RNP RNAV is based on the following systems, where these systems meet navigation requirements: • GNSS • GNSS/INS • DME/DME/INS • ADS-B Atlanta

  9. Brisbane - Australia • Six Tailored RNP approach procedures were developed, three each for RWY01 and RWY19 • 33 RNP capable 737-800 aircraft, 12 of which are also ADS-B equipped • RNP value of 0.3 used for procedure design: • Obstacle clearance area extends 1,111 meters on both sides of flight path • Aircraft required to meet a track keeping navigation performance not to exceed 556 meters on either side of flight path • Radar, with a position accuracy of 93 meters, does not meet measurement requirements • ADS-B and differential GPS used to measure and calibrate results

  10. Results Initial results show that the aircraft conform to the path prescribed in the RNP- AR procedure with a standard deviation of less than 20 meters. The wing span of the aircraft is 36 meters.”

  11. Trajectory Based Operations (TB0) • “A major transformation in NextGen is the use of TBO as the main mechanism for managing traffic in high–density or high-complexity airspace.” • Acronyms: • 4DT - Time • CTA – Time Window • RTA – Required Time

  14. Ongoing R&D • Florida TestBed • OPD’s - Miami • Daytona • UPS • Merging and Spacing • Self Seperation • Ongoing • Southwest • RNP Operations • Defunct • DayJet • Start Ups • USAir/ACSS • NetJets

  15. Completed Memoranda of Understanding • Agreement with NetJets to test NextGen technologies • Partnership with Southwest Airlines to make its entire fleet and route structure RNAV/RNP-capable • Agreement with South Jersey Economic Development District to build aviation research and technology park • Agreement with USAir/ACSS to evaluate the operational capabilities of ADS-B NextGen equipped aircraft • ADS-B • RNP/RNAV • Focused on PHL • Use A330’s • SWAM

  16. NextGen Demonstrations to Support Investment Decisions • AIRE demonstration resulting in 330 gallons of fuel savings and 6,700 lbs emission reduction • Continuous descent arrival and tailored arrival demonstrations at Miami and Atlanta (OPD) • ASPIRE demonstration resulting 4 percent fuel savings and 11 metric tons emission reduction • Demonstration of weather integration into decision support at Embry-Riddle test bed in Florida • Demonstration with Harris Corp. to support future SWIM segments as defined in the NAS Enterprise Architecture • Initial demonstration of 3D path arrival management in Boeing simulation labs • Demonstration of enhanced surface flow management to improve aircraft taxi coordination and planning

  17. R&D Needed • Well over 100 topical research areas • High priority • Funding Available • FAA • NASA • NGATS Institute • Homeland Security

  18. Provoking Thought • Self Separation for GA IFR Operations! • We do it now: • VFR • Uncontrolled airspace IFR • With ADS-B • Key Issues • Equivalent Level of Safety • Supporting Data • Cost/Benefit • Air Traffic / Mixed Equippage
