Transition from ground based surveillance to satellite centric operations Transition from ground based surveillance to satellite centric operations Divestment Divestment Strategic Investment decision with positive long term cost / benefit Strategic Investment decision with positive long term cost / benefit Support aviation community demand Support aviation community demand Enhances safety and capacity Enhances safety and capacity

6. ADS-B Why might the aviation community support ADS-B? General Aviation Flight Information Service – Broadcast (FIS-B) Flight Information Service – Broadcast (FIS-B) Traffic Information System - Broadcast (TIS-B) Traffic Information System - Broadcast (TIS-B) Supports reduced costs imposed by FAA Supports reduced costs imposed by FAA Situational Awareness and Safety enhancements akin to current Capstone program in Alaska Situational Awareness and Safety enhancements akin to current Capstone program in Alaska

7. ADS-B Why might the aviation community support ADS-B? Commercial Aviation Supports future reductions in separation standards from current standards to meet 2020-2025 demand. Supports future reductions in separation standards from current standards to meet 2020-2025 demand. 5 mile enroute / 3 mile terminal separation standards are unlikely to meet this demand5 mile enroute / 3 mile terminal separation standards are unlikely to meet this demand Supports future capacity enhancements Supports future capacity enhancements With navigation enhancements, will benefit arrival and departure ratesWith navigation enhancements, will benefit arrival and departure rates Establishes the foundation for future cockpit safety and situational applications Establishes the foundation for future cockpit safety and situational applications VFR like separations in some casesVFR like separations in some cases Surface surveillance applicationsSurface surveillance applications

8. ADS-B Why is the aviation community working through RTCA to develop recommendations for a Proposed Rule associated with ADS-B? Establishes a collaborative model where FAA and aviation community develop the future in a collaborative manner Establishes a collaborative model where FAA and aviation community develop the future in a collaborative manner “Road to NexGen” passes through ADS-B “Road to NexGen” passes through ADS-B Lays the foundation for future system enhancements Lays the foundation for future system enhancements Addresses many of the “transition” issues of moving to a aircraft centric NAS Addresses many of the “transition” issues of moving to a aircraft centric NAS

Equipage Curves G A uses a 10 year equipage cycle G A uses a 10 year equipage cycle GPS or GPS / WAAS requirementsGPS or GPS / WAAS requirements Challenges relative to backup scenario where surveillance source (GPS) is not availableChallenges relative to backup scenario where surveillance source (GPS) is not available Regional Community uses 7 year retrofit Regional Community uses 7 year retrofit Lack of Inertial introduces GPS backup concernsLack of Inertial introduces GPS backup concerns Augmentation may be requiredAugmentation may be required Commercial Carriers use 7 year retrofit cycle Commercial Carriers use 7 year retrofit cycle Augmentation may be requiredAugmentation may be required

12. Cost Benefit story Business Case is annualized through 2035 Business Case is annualized through 2035 Pay back to FAA and to Aviation Community is not immediate Pay back to FAA and to Aviation Community is not immediate Aviation Community ADS-B business assessment is challenging Aviation Community ADS-B business assessment is challenging Lays the groundwork for future benefit Lays the groundwork for future benefit Establishes the foundation for enhanced Surveillance and Navigation Establishes the foundation for enhanced Surveillance and Navigation

13. Cost Benefit story Fundamental Issues/Questions are: Fundamental Issues/Questions are: 1.Do you believe in the projections of at least double current capacity in 2020 - 2025? 2.Do you believe “the transition” ever goes away? 3.Do you believe the service provider or the aviation community can make fundamental, “earth changing” decisions in isolation?

14. Consequences of Failure 1.Do you believe in the projections of at least double current capacity in 2020 -2025? 100+ seater projections 100+ seater projections 13000 today13000 today 27000 by 202527000 by 2025 2.Do you believe “the transition” ever goes away? Plans and Vision are easy Plans and Vision are easy Transitions are Hard Transitions are Hard 3.Do you believe the service provider or the aviation community can make fundamental, “earth changing” decisions in isolation?
