What components are powered by the C hydraulic system?

1. Flight controls, slats, flaps, and landing gear

2. Normal brakes, autobrakes, and accumulator brakes

3. Right thrust reserve and taxi brake release

4. Emergency lights and cabin pressure control

The correct answer is: Flight controls, slats, flaps, and landing gear

The C hydraulic system is commonly responsible for operating critical components of the aircraft, such as flight controls, slats, flaps, and landing gear. These components are essential for the safe and effective operation of the aircraft. Flight controls directly influence the aircraft's ability to maneuver in the air, while slats and flaps enhance lift and slow down the aircraft during landing and takeoff. The landing gear is vital for supporting the aircraft during ground operations. The reliability and functionality of the C hydraulic system is crucial, as any failure in these components could significantly impact flight safety. The other options listed focus on different systems or components that are typically powered by other hydraulic systems or mechanisms. For instance, normal and autobrakes primarily operate through a separate hydraulic system, which is distinct from those handling flight control surfaces and landing gear. Therefore, the C hydraulic system is appropriately tasked with the responsibility for the components identified in the correct answer.
