What best describes a multifunction display (MFD)?

• A. A small screen (CRT or LCD) in an aircraft that can display information to the pilot in configurable ways, often used with a primary flight display.
• B. A primary flight display that shows attitude and speed.
• C. An autopilot component used for navigation.
• D. A standalone GPS unit.

Answer: (A)

A multifunction display is a flexible cockpit screen that can present multiple kinds of information from different systems in configurable layouts. It’s not limited to one function; you can switch between pages showing navigation, weather, engine data, flight plans, maps, and more, all on the same screen as needed. This adaptability is what makes it a multifunction display, and it’s typically used alongside the primary flight display, which handles the basic attitude and flight data.

That’s why the described option fits best: it mentions a small screen (CRT or LCD) that can display information to the pilot in configurable ways and is commonly used with a primary flight display. The other options refer to a primary flight display (focused on attitude and airspeed), an autopilot component, or a standalone GPS unit—each is a different function, not the versatile display described.
