Controlled Flight Into Terrain (CFIT) refers to an accident or incident in which an airworthy aircraft, under full control of the pilot, unintentionally flies into terrain, obstacles, or water without prior awareness of the impending collision. In CFIT events, the aircraft is not malfunctioning, and the pilots are usually unaware of the danger until it is too late.
According to ICAO and industry data, CFIT has historically accounted for a significant proportion of aviation fatalities, particularly in approach and landing phases. Most CFIT accidents are preventable with proper situational awareness, adherence to procedures, and technology use.
