Honolulu International Airport in Hawaii has installed a new radar system to prevent collisions and forecast potential problems on the runway and taxiway.
The airport surveillance detection system will be installed atop the flight control tower to send audio and visual signals to air traffic controllers about potential dangers on the runway.
The radar will be able to detect objects much smaller than a plane and increase aircraft safety during the night and in bad weather when visibility is poor.
The $15m radar, which is still in its preparation phase at the airport, will be made operational by October 2010, according to khon2.com.
A similar system will be deployed at 34 other airports in the US including in Chicago, Atlanta and Los Angeles by the end of this year.
