What is displayed when the MFD System (SYS) switch is pushed in the flight deck?

• A. Flight paths are displayed
• B. Hydraulic quantities are displayed
• C. Engine temperatures are displayed
• D. Fuel levels are displayed

Answer: (B)

When the MFD (Multi-Function Display) System switch is pushed, it activates the display of hydraulic quantities. This is an essential feature in the flight deck as it allows pilots to monitor the hydraulic system's status, which is critical for the functioning of various flight control systems, landing gear, and other aspects of aircraft operation. Proper hydraulic quantities ensure that the aircraft systems receive adequate pressure and fluid levels necessary for safe and effective performance. While other choices like flight paths, engine temperatures, and fuel levels are indeed important data points in aviation, they are generally displayed based on different switches or systems. The specific function of the MFD System switch is to provide real-time information about the hydraulic system, which is vital for assessing the aircraft's operational readiness and safety during flight.
