What is the function of a terrain awareness warning system (TAWS)?

A terrain awareness warning system (TAWS) is designed specifically to enhance flight safety by alerting pilots of potential terrain collisions. It continuously monitors the aircraft's position, altitude, and flight path in relation to the surrounding terrain. By providing timely warnings when the aircraft is at risk of flying too close to the ground or mountains, pilots can take corrective actions to avoid accidents.

This function is critical in preventing controlled flight into terrain (CFIT) incidents, particularly in challenging environments where visibility may be limited or when flying at low altitudes. The alerts provided by a TAWS can be crucial for making quick decisions that ensure the safety of the aircraft and its passengers.

Other functions, such as providing entertainment, enhancing fuel efficiency, or improving communication among crew members, are unrelated to the primary safety purpose of a terrain awareness warning system.
