2. Agenda • FAA AIRE Initiatives • Oceanic Optimization Trials • Gate to Gate • Surface Optimization • Continuous Descent Operations (CDO) • Optimized Profile Descent (OPD) • Tailored Arrivals (TA)

3. FAA Overview of AIRE Program • FAA AIRE “Program Office” is part of the Technology Development & Prototyping group • FAA uses a partnership approach to establish early NextGen capability demonstrations • Demonstration activities are organized into surface, enroute/oceanic, and arrival domains. Gate to gate demonstrations integrate all domains

4. FAA Oceanic Optimization Trials Initiated in 2008, continued into 2010 Main Objectives To validate savings using existing technology to request and execute lateral reroutes over the Atlantic Demonstrate feasibility of integrating optimized oceanic trajectory with a tailored arrival (TA) ANSP Partners FAA (New York FIR), NAV Portugal (Santa Maria FIR) ZNY employed Advanced Technologies Oceanic Procedures (ATOP) Ocean21 to track aircraft using FANS-1/A CPDLC The Santa Maria automation system is compatible with the Ocean21 system

5. FAA Oceanic Optimization Trials • Airline Partners, Air Europa and Lufthansa • Aircraft transmitted GPS position, Flight Level and next trajectory change points at agreed (contracted) intervals, approximately every 20 minutes • Aircraft in the trial equipped with FANS 1 or FANS-1/A (Airbus) equipage and were capable of using the full CPDLC message set • Aircraft types: A 330, B 747

6. FAA Oceanic Optimization Trials • The AOC dispatcher monitors the progress of the flights and the actual weather, assessing whether a lateral reroute would reduce flight time and/or fuel. • If a reroute is predicted to be more efficient, the dispatcher generated an amended flight plan and uplinked the suggested reroute to the aircraft • The flight crew checked the uplinked route, and if it agreed, down-linked the reroute as a CPDLC DM-24 reroute message to the oceanic controller. If the aircraft intended to carry out a TA, then 40 minutes prior to oceanic exit, the flight crew would request a TA clearance from ZNY. • Ocean21 is used by the controllers to probe for conflicts when aircraft requested a lateral reroute. If the reroute is determined safe, the controller would issue a CPDLC clearance to the aircraft. If there were conflicts with the reroute, then the controller would deny the reroute, up-linking an ‘UNABLE’ CPDLC message with an attached explanatory free-text message to the aircraft. If time allowed, the controller could offer an alternate clearance partially meeting the aircraft reroute request. • Finally, the flight crew will relay the clearance response from the controller to the dispatcher.

10. Planned FAA 2011 AIRE Initiatives • Main objectives • Build on AIRE achievements in prior years • Highlight interoperability • Focus on the following domains • Enroute/Oceanic Optimization • Surface Management • Arrival Optimization • Expand Scope • Additional carriers and operators • Airframe types • City pairs

11. Planned FAA 2011 AIRE Oceanic Optimization Initiatives • Department of Defense • US Air Force Air Mobility Command (AMC) transatlantic flights • CDO to CHS • Business Aviation • Trans-Atlantic operators • Partner with SJU Oceanic Demonstrations

12. Planned FAA Support for SJU Initiatives • Air France Transatlantic Green Flight ORY-PTP • Objective: Optimize a transatlantic flight from departure gate to arrival gate • Optimization laterally and vertically; descent optimization planned • The Air France dispatcher checks for a more optimized route, for example at TOC (Top Of Climb) or after a weather update • If better route is found, it is proposed to cockpit crew for approval • If approved by cockpit crew, reroute is requested to ATC for clearance • If cleared by ATC, the crew accepts the reroute • No intention to do a “cruise climb” trial FAA Interaction

13. Planned FAA Support for SJU Initiatives • FAA will accommodate optimization requests based on traffic, weather, workload and other factors • New York (KZNY) and Santa Maria (LPPO) FIRs already accept reroute requests • Demonstration procedures may be broken at any point by either ANSP or operator

14. Planned FAA Support for SJU Initiatives • First come, first served protocol will be observed • Demonstrations should not adversely impact other flights • No CPDLC position reports • Ocean21 does not support CPDLC position reports in the ARINC 424 format.  Consequently, ADS should be used for position reporting, and not CPDLC
