Advanced ATM Techniques Symposium and Workshops Today’s Opportunities for Saving Fuel and Reducing Emissions

4 – 6 November 2013, ICAO Headquarters, Montréal

KJFK Runway 13R-31L Rehabilitation

ATFM Strategies

Stephen McMahon

Manager, System Efficiency

Federal Aviation Administration

Background

• Between March 1 and June 28 2010,

KJFK rebuilt its busiest runway, 13R/31L

– Asphalt replaced by concrete to reduce life-

cycle costs

– Widened from 150 feet to 200 feet

– Enhanced exit taxiways, upgraded marking

and lighting systems

Advanced ATM Symposium and Workshops,

4 - 6 Nov 2013, Montréal, Canada 2



Why is This Significant?

• KJFK is the busiest international air

passenger gateway to the U.S.

– 13R/31L handles one third of KJFK’s total air

traffic, including more than half of its

departures



Overview

• Collaborative Decision Making (CDM) was

used to establish goals and explore

strategies

• ATFM was used to implement strategies

and measure success



Goals and Strategies

• The CDM community met regularly to

minimize construction impacts

– Mitigate surface congestion

– Minimize delay



Mitigate Surface Congestion

• Departure Metering Goals – Minimize airfield congestion, taxiing delays, fuel

burn and emissions

– Reduce ATC frequency congestion

• Departure Metering Strategies – Use virtual taxi queues to produce shorter

physical queues of aircraft waiting to depart

– Hold flights at the gate or in a common metering area and assign a departure slot prior to entering an active taxi queue

– Limit physical departure queue to 10-15 aircraft Advanced ATM Symposium and Workshops,


Minimize Delay

• Delay Goal

– Keep total delay at or below 2009 levels

• Delay Minimization Strategies

– U.S. domestic carriers agree to manage their Spring 2010 flight schedules and match the reduced capacity of the runway system

– Fewer ATFM measures

– Alter runway and airspace use plans to allow runway 31R departures



Measuring Success

• Departure Queue Length

• Number of ATFM Measures implemented

• Balance of demand with available capacity

• Runway and airspace use

• Delay measures

• Environmental performance

Environmental Performance

• Annualized benefits of continued KJFK

Departure Metering

– Five million fewer gallons of fuel burned

– Reduction of 48,000 metric tons of CO2

emitted into the atmosphere

– $10M-$15M (est.) savings across carriers

participating in the metering program

Lessons Learned

• Construction activity enhanced understanding of how to manage surface operations – Proactively managing physical queues of aircraft waiting to

depart

– Benefits continue to be realized

• Airport Construction Advisory Council formed to prepare stakeholders for changes on the airport surface during construction – Providing input to the ICAO Airport Service Manual
