Changed 'barometer' to 'altimeter' to be more clear.

It was initially developed by the military as "terrain-following radar" for low-altitude bombers and strike fighters like the B-1B and F-15E, and a simplified version found its way into commercial airframes as the "Terrain Avoidance Warning System" or TAWS. | |
