Automatic Dependent Surveillance – Broadcast (ADS-B)What is it, and how can it help improve operations in Micronesia? Captain Rocky Stone Chief Surveillance Pilot United Airlines Pacific Aviation Directors Workshop March 15, 2012
What is ADS-B? • ADS-B is a surveillance system that relies on aircraft transmitting their current position • ADS-B ground stations are much less expensive than radar, and much more capable • Aircraft transmits position and velocity twice a second • With GPS navigation, ADS-B is more accurate than radar • ADS-B allows not only the ground to receive the position information, but close by aircraft can also “see” ADS-B transmissions, enabling air-to-air applications in addition to “radar like” air-to-ground applications
Why is the FAA moving forward with ADS-B? • ADS-B is an enabler for most “NextGen” procedures that increase safety, capacity, and efficiency • Interval Management (IM) – maximizes throughput to capacity constrained airports • In Trail Procedures (ITP) – increases the probability that aircraft on long oceanic flights will be able to fly at their optimum altitude, reducing fuel burn and emissions
What will ADS-B do for Micronesia? • ADS-B provides ATC a “better than radar” surveillance system • Airports which ATC currently only allows “one in/one out” stand to gain significant capacity • Eliminates most airborne holding – reduces fuel burn and emissions • Greatly reduces the probability of diversion • Increased safety, as ATC always knows exactly where the aircraft are
