Which of the following are types of brake actuating systems?

The correct option highlights the types of brake actuating systems by categorizing them based on their design and operation. Independent master cylinders and boosted brakes refer to systems that function separately from each other, allowing for greater control and redundancy in braking capabilities. Independent master cylinders operate individually for each brake system, providing a backup in case one fails, while boosted brakes utilize a mechanism to amplify the force applied to the brakes, improving braking efficiency with less effort exerted by the pilot.

Understanding the importance of these components is crucial in aircraft operations, as it directly relates to safety and performance. Independent systems ensure that if one brake system fails, the other can still provide adequate stopping power. Additionally, boosted brake systems enhance the pilot’s ability to control the aircraft during landing and taxiing by offering increased braking force.

Other options discuss various brake systems but do not encompass the full functionality and design of the actuating methods as effectively. Therefore, while they might mention valid concepts, they do not represent the types of brake actuating systems in the same comprehensive manner as independent master cylinders and boosted brakes do.
