What are the types of braking systems that can be applied in flight?

The choice indicating “Ground spoilers, disc brakes, reverse thrusters” represents components commonly implemented in aircraft braking systems, which effectively help in deceleration during flight and landing phases.

Ground spoilers are devices that extend from the wings to disrupt airflow and reduce lift, allowing for an increased rate of descent and quicker deceleration once the aircraft touches down. This action enhances the efficiency of braking by shifting the aircraft's weight forward onto the main wheels, thus maximizing friction between the tires and the runway.

Disc brakes operate similarly to those found in automobiles, using friction to slow down the aircraft. These are typically mounted on the wheels and engage when the pilot applies the brakes upon landing or during taxiing.

Reverse thrusters, which are mechanisms that redirect engine thrust forward, assist in slowing down an aircraft after touchdown. By changing the direction of thrust, they help to reduce the runway distance required for the aircraft to stop.

This combination of systems plays a pivotal role in ensuring a safe and effective landing process, providing pilots with multiple means of managing the aircraft's speed and descent.
