FAA and the City of Los Angeles are partnering to install a Runway Status Lights system at Los Angeles International Airport (LAX).

The system uses a series of red lights embedded in the pavement to warn pilots if it is unsafe to cross or enter a runway.

Los Angeles World Airports is funding the US$6 million cost of the system, on which tests will begin at LAX early next year.

FAA will be responsible for installing, testing, evaluating and maintaining the system.

"This is another valuable tool we're using to reduce the risk of runway incursions," FAA Acting Administrator Bobby Sturgell said.

Pilots approaching a runway equipped with Runway Status Lights will see red lights illuminated if the airport's ground surveillance radar detects traffic on or approaching that runway.

RSL systems are already in place at Dallas/Fort Worth and San Diego.
