1st ANNUAL WORKSHOP
NAS-WIDE SIMULATION IN SUPPORT
OF NEXTGEN:
REQUIREMENTS AND CAPABILITIES

Workshop Background
• NAS-wide Simulations will play a major
role in the development of NextGen
Concepts-of-Operations
– authorization of development funding
– authorization of implementation funding
CENTER FOR AIR TRANSPORTATION SYSTEMS RESEARCH

Objective of Workshop
•
Identify potential “gaps” for NAS-wide
Simulation
1. What Con-Ops should be simulated in NASwide Simulation
2. What “functions” are required to model a
given Con-Op
3. Risks (Con-op not defined, performance
measure ambiguous, algorithm to support
absent)

Definition: NAS-Wide Models
•
•
Simulates the performance of the NAS at the granularity of individual flights
over the course of one day.
Sequencing of individual flights through runways and airspace
– may include gates and taxiways
•
Inputs:
–
–
–
–
•
Flight Schedule for Day (itinerary, fleet assignment, seat size, engine-types),
routes and Crz FLs (optional),
Airport Arrival/Departure Capacity, Sector capacity,
Flow Management (may include delays, sequencing, and re-routing for weather)
Outputs:
–
–
–
–
–
Delays per Flight (Delays per flight segment)
Actual Airport Arrival/Departure
Airspace Utilization,
ATCo workload, complexity,
Fuel Burn, Noise, Emissions

NextGen NASwide Sims (Concept Elements
Proposed)
Flight Schedule for Day (itinerary, fleet assignment, seat
size, engine-types),
Tail Number Tracking
Dynamic Scheduling
Routes and Crz FLs (optional),
Re-routing
4DTs, gate to gate
4DTs during super-density surface operations
Integrated Surface and Ramp Traffic Management System
4D trajectories negotiation between air and ground
Continuous Descent Approaches
Airport Arrival/Departure Capacity,
Sector Capacity,
Improved airport ability to operate in low visibility
Dynamic resource and airspace management
Delegated (airborne) separation
Closely Spaced Parallel Approaches
Flow Management (may include delays, sequencing,
and re-routing for weather)
Flow strategy and trajectory impact analysis
Safety
Improved runway incursion prevention algorithms

Workshop Outcomes
1. NextGen Con-Ops that should appropriately be
modeled in NAS-wide Simulations
–
e.g. Airborne Re-routing, integrated surface ops?
2. NAS-wide Simulation Functions required to support
NextGen Con-ops
–
e.g. Airborne Re-routing Con-Ops will require “functions” to
perform: route planning function, trajectory conflict detection
3. Risks
–
–
–
NextGen Con-Ops not defined in sufficient detail (e.g. Dynamic
Airspace Allocation)
No consensus on definition of Performance Measure (e.g.
Probabilistic Capacity)
Algorithms/Behaviors need to be developed and tested
