Engine failure on take-off
Engine failure on take-off (EFTO) is a situation, when flying an aircraft, where an engine has failed, or is not delivering sufficient power, at any time between brake release and the wheels leaving the ground / V2. The phases of flight are de-lineated to allow simplified standard procedures for different aircraft types to be developed. If an aircraft suffered engine failure on takeoff, the standard procedure for most aircraft would be to abort the takeoff.
