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 2

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 3

ITP Opportunities 4

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 5
