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

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

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

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.

Trajectory Based Operations (TB0)

• A major transformation in NextGen is the use of
  TBO as the main mechanism for managing traffic in
  highdensity or high-complexity airspace.
