4 ATD-1 Demonstrate NextGen Performance-Based Navigation arrival-management methods to save fuel, reduce noise, and maximize the use of existing capacity Schedule arrivals for de-conflicted Continuous Descent Operations (CDOs) Use ADS-B-enabled Flight-Deck Interval Management (FIM) for increased inter-arrival precision Accelerate transfer of NASA-developed technologies Collect operational data and provide to partners and stakeholders Interval Management Terminal-Area Precision Scheduling System (IM-TAPSS)

5 TRACON Center Airspace ATD-1 Concept of Operations Scheduling TMA-TM assigns runways, computes schedules for meter-fixes, terminal-area fixes, runways Preconditioning Controllers use speed, path assignments to adjust aircraft toward frozen schedule Descent/FIM Initiation Merging/Spacing Adjustments Controllers issue descend via CDO clearances, FIM clearances to equipped aircraft Controllers use CMS tools to issue speeds to unequipped aircraft, monitor FIM operations B.

25 Subjective Results TMA-TM schedules mostly rated as achievable, stable, and accurate En-route speed advisories rated only moderately accurate and stable Controllers largely successful in maintaining scheduled throughput levels All CMS tools rated acceptable, but slot markers rated less stable than timelines; controllers expressed a desire to flexibly control when slot markers are displayed for particular aircraft No significant differences in ratings for slot markers and timelines only, versus full toolset with third-line information FIM clearances rated between moderately manageable and very manageable ; controllers gave high ratings for read-back clarity, accuracy, and timeliness FIM status designators rated favorably; Center controllers rated status-updating task very acceptable, TRACON controllers reasonably acceptable FIM operations increased task complexity, but not excessively 25
