What are the three types of braking systems used in aircraft?

The correct choice highlights the three primary types of braking systems used in aircraft: ground spoilers, disc brakes, and reverse thrusters.

Ground spoilers are devices that extend from the wings of the aircraft when it lands. They disrupt the airflow over the wings, reducing lift and allowing the aircraft to settle more quickly onto the runway. This rapid decrease in lift enhances the effectiveness of the brakes, as the aircraft can apply them more effectively.

Disc brakes are commonly used in aircraft due to their efficient heat dissipation and consistent stopping power. These brakes consist of discs attached to the wheel that are squeezed by brake pads, creating the friction needed to slow down or stop the aircraft. The reliability and effectiveness of disc brakes make them a standard choice in modern aviation.

Reverse thrusters, utilized primarily during landing, redirect the engine's thrust forward. This action provides additional deceleration, helping to shorten the landing distance. By combining these mechanisms, aircraft can achieve effective stopping power, which is critical in ensuring safety during landing operations.

The other options include components or systems not typically categorized as primary braking types. For instance, while electric brakes are relevant in certain systems, they are less common than disc brakes in commercial aviation. Similarly, options mentioning parachute brakes or wheel brakes might
