 If a serious failure occurs or is suspected above V1 but the airplane's ability to fly is not in doubt, the takeoff is continued despite the (suspected) failure and the airplane will attempt to land again as soon as possible.Single-engine aircraft will reject any takeoff after an engine failure, regardless of speed, as there is no power available to continue the takeoff.Even if the airplane is already airborne, if sufficient runway remains, an attempt to land straight ahead on the runway may be made.
