A system for an aircraft, the system comprising: at least one inertial sensor producing a first signal; at least one wind speed sensor producing a second signal; and at least one flight computer, operatively coupled to the at least one inertial sensor and the at least one wind speed sensor, the at least one flight computer configured to: measure an acceleration (204-B) in response to the first signal; calculate an expected estimated acceleration value (204-A) in response to an estimated aircraft weight, runway information, weather parameters, and takeoff configuration; compare the measured acceleration (204-B) with the expected estimated acceleration value (204-A); determine whether the measured acceleration differs significantly from the expected estimated acceleration value; in response to the second signal, determine whether the aircraft is operating below an upper limit speed guaranteeing that the aircraft can safely perform a low kinetic energy rejected takeoff without the risk of a runway excursion or overrun; if the measured acceleration is determined to differ significantly from the expected estimated acceleration value and the aircraft is determined to be operating below the upper limit speed, automatically issue control signals to automatically abort takeoff conditioned on both the comparison and the speed determination, the control signals controlling the aircraft to automatically execute a rejected takeoff by reducing or reversing thrust, applying brakes and increasing drag by controlling aerodynamic control surfaces to bring the aircraft to a safe stop. at least one inertial sensor producing a first signal; at least one wind speed sensor producing a second signal; and at least one flight computer, operatively coupled to the at least one inertial sensor and the at least one wind speed sensor, the at least one flight computer configured to: measure an acceleration (204-B) in response to the first signal; calculate an expected estimated acceleration value (204-A) in response to an estimated aircraft weight, runway information, weather parameters, and takeoff configuration; compare the measured acceleration (204-B) with the expected estimated acceleration value (204-A); determine whether the measured acceleration differs significantly from the expected estimated acceleration value; in response to the second signal, determine whether the aircraft is operating below an upper limit speed guaranteeing that the aircraft can safely perform a low kinetic energy rejected takeoff without the risk of a runway excursion or overrun; if the measured acceleration is determined to differ significantly from the expected estimated acceleration value and the aircraft is determined to be operating below the upper limit speed, automatically issue control signals to automatically abort takeoff conditioned on both the comparison and the speed determination, the control signals controlling the aircraft to automatically execute a rejected takeoff by reducing or reversing thrust, applying brakes and increasing drag by controlling aerodynamic control surfaces to bring the aircraft to a safe stop. measure an acceleration (204-B) in response to the first signal; calculate an expected estimated acceleration value (204-A) in response to an estimated aircraft weight, runway information, weather parameters, and takeoff configuration; compare the measured acceleration (204-B) with the expected estimated acceleration value (204-A); determine whether the measured acceleration differs significantly from the expected estimated acceleration value; in response to the second signal, determine whether the aircraft is operating below an upper limit speed guaranteeing that the aircraft can safely perform a low kinetic energy rejected takeoff without the risk of a runway excursion or overrun; if the measured acceleration is determined to differ significantly from the expected estimated acceleration value and the aircraft is determined to be operating below the upper limit speed, automatically issue control signals to automatically abort takeoff conditioned on both the comparison and the speed determination, the control signals controlling the aircraft to automatically execute a rejected takeoff by reducing or reversing thrust, applying brakes and increasing drag by controlling aerodynamic control surfaces to bring the aircraft to a safe stop.
