What principle does a multi-function display (MFD) use to present data?

A multi-function display (MFD) utilizes the principle of integrating various flight data into a single display to present information efficiently to the pilot. The MFD consolidates and presents essential information such as navigation data, weather information, engine parameters, and flight status, all in one view. This integration simplifies the cockpit layout and allows pilots to monitor multiple systems without the need to switch between different displays or gauges. By providing a cohesive and comprehensive view, MFDs enhance situational awareness and decision-making in flight operations, which is critical for safety and operational efficiency.

In contrast, separating flight data across multiple screens could lead to information overload and make it more difficult for the pilot to maintain situational awareness. Likewise, isolating critical information does not take advantage of the benefits of integration that an MFD provides, as it can restrict the availability of important data at a glance. Similarly, real-time video streaming of external conditions, while useful in some contexts, is not the primary function of an MFD, which focuses more on data integration rather than purely visual representation.
