Terrain awareness and warning system
From Wikipedia, the free encyclopedia
Terrain Awareness and Warning System (TAWS) attempts to reduce controlled flight into terrain by improving on current ground proximity warning systems. TAWS does this by using digital elevation data and airplane instrumental values to predict if a likely future position of the aircraft intersects with the ground.[1] The flight crew is thus provided with "earlier aural and visual warning of impending terrain, forward looking capability, and continued operation in the landing configuration." [2]
In March 2000, the Federal Aviation Administration issued two mandates for Part 91, 121, and 135, requiring all US, turbine powered aircraft to be equipped with TAWS if certified to carry six or more passengers.[1][2] The mandate only effects aircraft manufactured after March 29, 2002.[3]
