Aircraft that have a balanced field length in the POH, must be able to continue takeoff in case of engine failure, or stop on the remaining runway.
For example, if the balanced field length is 6,000 feet, and the aircraft can't stop in the remaining length after rotating, or continue the takeoff on the remaining engine(s), it would be illegal for them to use that runway.

A "balanced field" is the term for a runway that has sufficient length for a multiengine aircraft to accelerate to the takeoff decision speed (V1) at which point there is an immediate crew decision to reject the takeoff and take all actions necessary (e.g., select idle or reverse thrust and apply full braking) to bring the aircraft to a safe stop on the remaining runway. Its significance is especially critical when an engine has failed during the takeoff run. If the aircraft is below the V1 speed when the engine fails, and is operating on a "balanced field" runway, the crew know there will be sufficient runway remaining to recognize the failure and then react to it by taking actions to reject the takeoff. If an engine fails above V1 there is sufficient runway remaining (and sufficient thrust from the remaining engine(s) to continue the takeoff roll, become airborne, and actually fly the aircraft on a safe climb profile followed by an immediate return to the field.

Hey, everybody got it right. Who says procrastination doesn't pay. May all your fields be balanced and your runways long.
