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

9 June 2010 | By 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…


Opportunities for reducing surface emissions

28 March 2008 | By 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
