Goals Remain the Sameqwqq[[[ • Aviate • Navigate • Separate
NextGen: Using 21st Century Technology to: • Increase Capacity • Increasing Airport/Airspace Capacity • Reducing complexity for Air Traffic Controllers • Simplify Communication • Reduce Maintenance Costs • Improve Environmental Impact • Maintain or Improve Traditional Safety Standards
Increase Capacity: Build • Build More Runways: reduce bottleneck for takeoffs and landings • Open up additional Airspace
Increase Capacity: Utilization • Reduce Distance between following Aircraft • Use Required Navigation Precision (RNP) • Automatic- Dependent Surveillance –Broadcast to provide ATC exact aircraft location • Cockpit Display of Traffic (CDTI) • Digital Communications • Reduce Distance for Aircraft on Parallel tracks • Use Required Navigation Precision (RNP) • Automatic- Dependent Surveillance –Broadcast to provide ATC exact aircraft location • Digital Communications
Increase Capacity: Coordination • Eliminate unused slots by coordinating flow • Spacing and merging • Super dense operations • Utilize digital communications
Increase Capacity: Reduce ATC Complexity • More Accurate Aircraft Location • Use Relative Position Indicator (RPI) to merge arrival flows, sequence and space aircraft • Automated Terminal Proximity Alert (ATPA) to help monitor final approach • Converging Runway Display Aid (CRDA) uses visual runway spacing cues on converging runways to aid in spacing • ADS-B • Reduces uncertainty • Digital Communications • Reduces uncertainty or need to re-transmit • Reduces Routing information errors
Reduce Maintenance Costs • Radar network spread across the continent • Maintenance of actual radar • Build/maintain roads to remote locations • Build/maintain facilities in remote locations • Aging Infrastructure
Improve Environmental Impact • Use of 4-D to make orchestration more optimal • Efficiently moving traffic reduces • Noise • Fuel burn • Flying at higher altitudes • Reduces fuel burn and pollution
Challenges • Technology Cycle • How do we integrate a system of systems that is constantly changing • Who incurs the cost and when? • Needed capability – managing new and old system • Incremental capability – start easy and move on
