DEFINITION:

To reduce the risk of aircraft colliding with each other, or by undertaking Controlled Flight Into Terrain (CFIT), aircraft are fitted with an array of collision warning systems. Note that human aspects of responses to warning system alerts are dealt with in the «Human Factors» research and technology area, and fire protection warning systems are dealt with later in this Area.
