Alaska Airlines is equipping its entire 737 fleet with the Honeywell Runway Awareness and Advisory System, the first major U.S. passenger carrier to equip its entire aircraft fleet with a system designed to help prevent accidents on runways and taxiways. The Runway Awareness and Advisory System (RAAS), developed by Honeywell in 2003, provides pilots with audible alerts when they approach and enter taxiways and runways. The system confirms runway identifications to help ensure pilots are on the correct runway with enough distance to complete takeoff, and provides an audible warning if a pilot inadvertently accelerates for takeoff while on a taxiway.
