Emirates has ordered Honeywell’s runway awareness and advisory system (RAAS) for installation in 107 Airbuses and Boeing 777s. The system is being demonstrated here for the first time in the Middle East aboard the US company’s Rockwell Sabreliner testbed aircraft. RAAS is designed to reduce the possibility of runway incursions by giving pilots a clear picture of their location and surrounding activity during taxiing, take-off and landing.
RAAS works by using GPS to locate the aircraft on a digital map of the airport and providing an audible warning on the flight deck at various times during movement on or close to the ground. The crew is alerted when the aircraft enters a runway, if it dwells on a runway for an extended period, and in the event of an attempt to take off from a taxiway or a short runway. The system can also provide runway distance-remaining call-outs during a rejected take-off or long landing.
In airborne mode, using data supplied by Honeywell’s enhanced ground proximity warning system (EGPWS), RAAS can identify the runway the aircraft is approaching and provide a warning if it is too short for a safe landing.
