New algorithms developed to help reduce airport congestion

Airport news  •  18 July 2016  •  Katie Sadler, Digital Content Producer, International Airport Review

A researcher at the Massachusetts Institute of Technology (MIT) has developed new algorithms to reduce airport congestion in the United States.

Dealing with the airport and its environment

Issue 5 2010  •  1 October 2010  •  Hamsa Balakrishnan, John-Paul Clarke, Eric Feron, and Marc Pélegrin

Airport infrastructure capacity is rapidly being approached in many cities around the world. Environmental factors, such as acoustic and chemical emissions, are increasingly less tolerated by neighbouring communities. The net result is that new means must be found that deliver more aircraft to the airspace with less environmental impact on the community, while maintaining the current level of safety enjoyed by air transportation. In this article, we investigate a few promising options to decrease the environmental footprint of airports.

A survey of airline pilots regarding fuel conservation procedures for taxi operations

Issue 3 2010  •  9 June 2010  •  Regina Clewlow, Hamsa Balakrishnan and Tom Reynolds, Massachusetts Institute of Technology

Aircraft taxi operations are a significant source of energy consumption and emissions at airports. In 2007, an estimated 4,000 tons of hydrocarbons, 8,000 tons of nitrogen oxides and 45,000 tons of carbon monoxide were emitted through taxi-out operations at U.S. airports1. These pollutants contribute to low-altitude emissions, directly impact local nonattainment of air pollution standards, and represent an endangerment to human health and welfare.Given increasing fuel prices and concern about aviation-related environmental impacts, airlines have implemented a number of practices to reduce fuel burn during ground operations.

Opportunities for reducing surface emissions

Issue 2 2008, Past issues  •  28 March 2008  •  Prof. Hamsa Balakrishnan, Department of Aeronautics and Astronautics, Massachusetts Institute of Technology

Flights in the United States spent more than 20 million minutes taxiing in to their gates and over 49 million minutes taxiing out for departure in the year 2006. Aircraft taxiing on the surface contribute significantly to the fuel burn and emissions at airports.

Accommodating the low cost revolution

Issue 1 2006, Past issues  •  17 March 2006  •  Richard de Neufville, Professor of Engineering Systems, Civil and Environmental Engineering, Massachusetts Institute of Technology

The issue of whether ’low-cost terminals are good for airports' is controversial and airports and airlines have diametrically opposite views. Speaking on behalf of the Airports Council International, its director general said: “LCCs [low-cost carriers] simply do not want the same services as legacy carriers (which form the bulk of IATA membership) and airport operators must be nimble enough to deliver ‘no frills’ facilities at lower cost to all carriers that want them”
