Today’s ATM Environment - Summary
• 1960’s system concept nearing/at limits of scaleability
• Substantial capacity/efficiency gains are technically achievable
• Fractured Gov’t, industry, operator, international marketplace makes for uncertain and long timelines for appreciable change
• Potential opportunity for Commercial Services approach to augment and/or accelerate improvements

Seven Steps to Deliver >3X Airport Capacity
1) Equivalent visual operations
2) Tailored arrivals at +/- 2 secs
3) All safe airspace exploited
4) 2-mile approach spacing
5) Pave down the middle
6) Multi-aircraft runway operations
7) All suitable airports used

An Initial 4D TBO
• Boeing chose to work the following operational improvement for three primary reasons
• It provides benefit to our airline customers• It creates real-world experience on key 4D issues• It demonstrates integrated datalink
• The improvement is in the arrival domain, but …• The key principles apply to most envisaged 4D TBOs• The key issues apply to most envisaged 4D TBOs

Tailored Arrivals
• Tailored Arrival — key features:• Continuous descent from cruise
altitude to touchdown• Tailored for traffic, environment, …• Controller-to-aircraft datalink*• Definition of flight path in both
time and space (4D)• Clearance through multiple centers• Uses available a/c capabilities
• Benefits:• 100 to 400 kg less fuel per flight• Flight duration reduced several min• Much less voice communication• Overall efficiency improved• Step toward modernization of ATM *If no datalink, tailored arrivals can use set
of arrival procedures pre-stored in FMS.

Ground automation generates TA trajectory clearance
E.g., EDA, TAATS
TA clearance delivered to aircraft over data link
CPDLC
TA clearance coordinated across ATC domains /systems
TA trajectory received and loaded into FMS on pilot concurrence
TA trajectory flown with FMS
Aircraft downlinks ETA information (at waypoints) along with other useful parameters for ATC trajectory confirmation and tuning
TA procedure broken off if trajectory cannot be continued for any reason

Wake Vortex Knowledge Crucial to NextGen/SESAR
In-trail spacing reduction needed to increase
airport capacity
Wake vortex display supports safe wake
avoidance
Closely spaced runways important for capacity at
some airports

Final Thoughts – Looking back from 2025
• Net centric architecture was core enabler• Precision navigation—fundamental requirement• Aircraft—nodes on the network• Capacity, safety, efficiency, security—concurrently
improved
• Three technical challenges needed solutions • Short-term weather forecast accuracy• Wake-vortex detection & prediction• Automation for Management by Trajectory
