  • Constant-angle non precision approach

  • CDFA is a technique, consistent with stabilized approach procedures, for flying the final approach segment of a non-precision approach (NPA) procedure as a constant descent, without level-off, from an altitude at or above the final approach fix altitude to a point approximately 15 m (50 ft) height above the landing runway threshold or the point where the flare manoeuvre should begin for the type of aircraft flown.
