From KING5, quoting WSJ:
SEATTLE - Safety experts say ground accidents are the greatest airline hazard, citing 24 serious near-collisions in the U.S. last year.

In the first safety move of its kind on passenger jets, Alaska Airlines has announced it will install technology aimed at preventing runway crashes.

Alaska Airlines is the first to provide this safety layer in the cockpit. It's called the Runway Awareness and Advisory System, or RAAS, designed to guide pilots through what seems routine on the ground, but can be very dangerous.

Just days ago, a runway incursion happened at Sea-Tac International Airport. An Airtran Boeing 737 had just landed at Sea-Tac from Baltimore when Northwest Flight 106 was departing for London. Airtran was supposed to hold its place, letting the Northwest Airbus take off. Instead, investigators say without clearance, the Airtran jet crossed in front, leaving the Northwest pilots barely enough space pull up.

An estimated 728 people have died of runway accidents between 1996 and 2007. Now, the first passenger airline will install Runway Awareness and Advisory System, which will guide pilots through the myriad of taxiways and make sure through verbal warnings that they have enough room to take off.

The Wall Street Journal reports Alaska Airlines has adopted four of the nine possible pilot warnings. Right now, makers Honeywell tell the Journal the system doesn't tell you if there is another plane on the runway, but technology companies are working on that.

Alaska Airlines plans to have the entire fleet of 112 of their 737s outfitted by the end of September.
