GPWS, or Ground Proximity Warning System, is a system that prevents aircraft from crashing into terrain. It uses radio altimeter information to detect if the airplane is coming too close to the ground and then provides the pilot with a verbal warning. Enhanced-GPWS, which has recently become available, stores a database of geographical features, can detect terrain in the forward direction, and issues a verbal and visual warning if the airplane is coming too close to terrain. All ANA aircraft have conventional GPWS, and we are working towards being the first Japanese airline to equip its entire fleet with Enhanced-GPWS. |
