Alaska Airlines will equip its entire fleet with Honeywell’s Runway Awareness and Advisory System (RAAS). Alaska Airlines began installing RAAS on its Boeing 737s in July. Alaska’s fleet will be fully equipped with the aural alert software by the end of September. RAAS, developed by Honeywell in 2003, provides pilots with audible alerts when they approach and enter taxiways and runways in an attempt to curb runway incursions. The system is a software enhancement to Honeywell’s Enhanced Ground Proximity Warning System (EGPWS), which warns pilots if they fly too close to terrain. Alaska began installing EGPWS in its aircraft in the mid-1990s and recently upgraded the system to provide pilots with visual alerts for tall buildings and other man-made structures.
