What is the standard action before V1 if takeoff cannot be continued safely?

• A. Continue takeoff if safe.
• B. Immediately perform a go-around.
• C. Climb and then abort.
• D. Abort the takeoff if possible.

Answer: (D)

Before V1 the priority is to stop the takeoff if continuing would be unsafe. V1 marks the speed at which there is still enough runway to stop safely, so when a condition arises that makes a safe continue impossible, the standard procedure is to reject the takeoff. This is done through a rejected takeoff maneuver: you command maximum braking, maintain directional control with the nose and rudder, and bring the thrust levers to idle while using reverse thrust and other available braking aids as the situation allows to stop within the remaining runway. After the aircraft is stopped, you exit the runway as instructed and follow the appropriate taxi and shutdown procedures. Continuing the takeoff would not be the best choice if safety cannot be assured, and a go-around isn’t the immediate action on the runway before liftoff. Climbing and then aborting isn’t the normal sequence for a threatened takeoff before reaching V1, since the aircraft hasn’t achieved the lift-off condition yet.
