* Wheel brakes: The primary means of braking for the 747 are its wheel brakes. These are large, disc-shaped brakes that are located on each of the aircraft's wheels. When the pilot applies the brakes, the brake pads squeeze the discs, which creates friction and slows the aircraft down.
* Spoilers: Spoilers are large, flat surfaces that are located on the top of the aircraft's wings. When the spoilers are deployed, they disrupt the airflow over the wings, which creates drag and helps to slow the aircraft down.
* Flaps: Flaps are large, hinged surfaces that are located on the trailing edge of the aircraft's wings. When the flaps are deployed, they increase the lift of the wings, which helps to slow the aircraft down.
* Reverse thrust: Reverse thrust is a technique that is used to reverse the direction of the thrust from the aircraft's engines. This creates drag and helps to slow the aircraft down.
In addition to these systems, the pilot can also use the aircraft's air brakes to help slow the aircraft down. Air brakes are large, flat surfaces that are located on the sides of the fuselage. When the air brakes are deployed, they create drag and help to slow the aircraft down.
By using a combination of these systems, the pilot is able to achieve the braking necessary to bring the 747 to a stop after landing.
