Rejected Takeoff

A Rejected Takeoff (RTO), also called an aborted takeoff, is the decision by the flight crew to stop the aircraft during the takeoff roll rather than becoming airborne. The decision must be made before reaching V1 (takeoff decision speed).

Before V1: Takeoff may be rejected for any reason — engine failure, tire failure, configuration warning, bird strike, ATC instruction, or any doubt about safety
At/After V1: Takeoff must continue unless the aircraft is unable to fly (catastrophic failure)
Procedure: Thrust levers to idle, full brakes, speed brakes deployed, reverse thrust
High-speed RTO is one of the most demanding maneuvers — brake energy can cause brake fires
ASDA (Accelerate-Stop Distance Available) must be sufficient for the aircraft weight and conditions
Crew training includes regular RTO practice in the simulator
