Abstract
The disclosed non-limiting embodiment provides important improvements in aircraft performance in short rejected takeoff systems by automatically detecting whether the speed of the aircraft does not exceed Vshort, where Vshort>V; automatically detecting whether one of said plural engines has failed during takeoff while the aircraft is still in contact with the ground; and if the aircraft speed does not exceed vshort and an engine has failed, automatically performing an autonomous abort takeoff sequence to allow an improved takeoff weight in case of a single engine failure autonomously rejected takeoff. The aircraft's take off weight increase leads to increased payload or fuel quantity. The Payload increase allows for increased passenger and/or cargo capability. The fuel quantity increased allows the aircraft to achieve greater ranges. An aircraft provided with the proposed system, which reduces accelerate-stop distance, may then operate in shorter runways as compared to the prior art.
