1. 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

2. 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

3. 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

5. 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
