CFIT (pronounced /si: fɪt/) is an acronym in aviation that stands for Controlled Flight Into Terrain. The term refers to an accident in which an aircraft, under pilot control, unintentionally crashes into the ground, water or some other obstacle. The spelling of the acronym is straightforward, with the letters C, F, I, and T pronounced using their respective phonemes. However, the pronunciation of /si:/ requires elongating the "s" sound, giving the word a distinctly different sound from the word sit.
CFIT stands for Controlled Flight Into Terrain. It refers to an aviation term that describes an accident in which an aircraft, under the control of the pilot, unintentionally crashes into the ground or water, causing substantial damage or loss of life. CFIT accidents typically occur when the pilot fails to recognize the imminent danger of colliding with terrain due to limited visibility, adverse weather conditions, inadequate instrument training, or other factors.
In these accidents, the aircraft is usually in good working condition, and the crew may not be experiencing any mechanical failure. CFIT incidents can occur during any phase of flight, from takeoff to landing, and are considered one of the most significant threats to aviation safety.
To address the issue of CFIT accidents, aviation authorities have implemented various safety measures, including advanced ground proximity warning systems (GPWS), terrain awareness and warning systems (TAWS), and enhanced pilot training programs. These systems provide real-time information and alerts to pilots regarding their proximity to the ground or potentially hazardous terrain features, giving them the opportunity to take necessary corrective actions.
Preventing CFIT accidents requires pilots to maintain situational awareness, adhere to instrument flight rules, conduct thorough pre-flight planning, effectively use onboard navigation and terrain avoidance systems, and continually update their skills through ongoing training and education.
