How many hydraulic systems does the B727 have?

One
Two
Three
Four

The correct answer is: Two

The Boeing 727 is equipped with three hydraulic systems. This design allows for enhanced redundancy and reliability in controlling various aircraft functions, such as landing gear operation, braking systems, and flight control surfaces. Each hydraulic system operates independently, ensuring that if one system fails, others can still maintain critical functions, significantly improving safety. The three systems also provide the necessary pressure and flow to support different aircraft subsystems. Understanding the number of hydraulic systems and their functionality is crucial for aircraft dispatchers as it relates to pre-flight planning and emergency procedures.
