  • In aviation, a controlled flight into terrain is also called CFIT which is usually pronounced as see-fit.
  • It means an airworthy aircraft, under pilot control, is unintentionally flown into the ground, a mountain, a body of water or an obstacle.
  • Spatial disorientation is the inability of a pilot to correctly interpret aircraft attitude, altitude or airspeed in relation to the Earth or other points of reference. Spatial disorientation in aircraft can arise from flight situations or visual misinterpretation. Banks and turns often create false sensations.
