how does aircraft brake to reduce speed when landed
In: Engineering
A combination of spoilers, engine reverse thrusters and brakes on the wheels.
The spoilers are upper surface flaps that deploy and disturb the airflow on the wing. They kill the lift on the wing to prevent the aircraft from getting enough lift to come up again, and create a lot of drag to help the plane slow down.
Engine reverse thrusters work exactly as the name implies. The jet plume from the engine is re-directed forwards, so the thrust acts backwards, thus slowing the plane down.
Wheel brakes work more or less the same as they do in a car.
