Controllers at Washington Dulles International on April 1 began using Airport Surface Detection Equipment, Model X (ASDE-X). Dulles is the 12th U.S. airport with the system, FAA said.
The new system is designed to work with future components of the Next Generation Air Transportation System (NextGen), a long-term process to improve safety, efficiency and capacity in U.S. aviation, FAA said.
Originally intended to be installed at 25 airports when FAA awarded the ASDE-X contract to Sensis Corp. in October 2000, ASDE-X deployment will be expanded to include 35 airports. FAA estimated that it will cost more than $806 million to procure, deploy and operate ASDE-X over a 30-year life cycle.
Other ASDE-X-equipped airports are Chicago O'Hare, Hartsfield-Jackson Atlanta International and Orlando International. Detroit Metro is scheduled to begin operating its ASDE-X in June, followed by New York's Kennedy International in August.
