1st ANNUAL WORKSHOPNAS-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


Objective of Workshop

• Identify potential “gaps” for NAS-wide Simulation

1. What Con-Ops should be simulated in NAS-wide 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 Con-OpsCurrent NAS-wide Sims (Con-Ops Supported) NextGen NASwide Sims (Concept Elements

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
