How are jet engines steered through the air?

Propulsion controlled aircraft system soon to be required on all jets as a backup system to steer airplanes which have lost hydraulic fluid rendering their hydraulic systems unusable and the airplanes aerlerons inoperable.

A computer aboard the jet airplane controls the amount of thrust coming out of each engine on the airplane.

If the pilot wants to turn right the computer will reduce the thrust coming out of the right engine and increase the thrust coming out of the left engine. If the pilot wants to turn left the computer will reduce the thrust coming out of the left engine and increase the thrust coming out of the right engine.

If the pilot wants to land the propulsion controlled aircraft system computer will gradually reduce the thrust coming out of both engines to lower the alltitude of the airplane. Jet engines supply the thrust for a plane. Directional control is done by the use of ailerons, elevators, & rudders, which alter the flow of air around the crafts wings & stabalizer.
