FAA Aircraft Dispatcher Complete Practice Exam

Question: 1 / 400

What type of devices does hydraulic System A on the B727 operate?

Only flight controls

Only landing gear

A combination including flight control surfaces and brakes

Hydraulic System A on the Boeing 727 operates a combination of systems, including flight control surfaces and brakes. This multifunctionality is essential for effective aircraft operation, allowing one hydraulic system to manage multiple critical functions.

In the B727, hydraulic systems are designed to ensure redundancy and efficiency. By enabling System A to handle both flight controls and brakes, the aircraft can maintain performance and safety levels even if one of the other hydraulic systems is compromised. This type of design reflects a common practice in aviation engineering, where critical systems are interconnected to enhance operational safety and reliability.

Understanding this integration is crucial for aircraft dispatchers, as it emphasizes the importance of hydraulic systems in managing multiple aircraft operations simultaneously, ensuring that all necessary functions remain operational during flight.
