What is the function of an MFD in an avionics suite?

• A. Multifunction Display that can show system pages, charts, ND/PFD overlays, and maintenance data.
• B. MFD shows engine data only.
• C. MFD displays only attitude indicator.
• D. MFD replaces the CPDLC.

Answer: (A)

The Multifunction Display acts as a flexible information hub in the cockpit, capable of presenting different kinds of data on demand. It can show system pages that summarize the status of aircraft subsystems, aiding fault finding and monitoring. It can display charts—navigation charts, airport diagrams, and other relevant plates—so pilots can access them quickly without flipping through separate devices. It can also render overlays for ND and PFD information, allowing navigation data, weather, traffic, terrain, and flight plans to be visualized together on one screen. In addition, it can present maintenance data and fault information from the health management system, which helps with troubleshooting and records. This broad capability makes the MFD the central tool for situational awareness and maintenance access, complementing the PFD and ND rather than limiting itself to a single data type. The engine data, attitude information, and primary flight indications have their own specialized displays, and CPDLC remains a separate data-link function for messaging rather than a replacement by the MFD.
