MFD

MFD is an acronym that can refer to several concepts, depending on the context and field.

In aviation, automotive, and maritime technology, MFD stands for Multi-Function Display. This is a screen or console that consolidates multiple information streams—such as navigation data, weather or traffic information, system status, and telemetry—onto a single interface. Modern MFDs are often configurable, allowing operators to choose which data are displayed and how they are arranged. In aircraft, MFDs are typically part of a larger glass cockpit system alongside other displays.

In computing, particularly in embedded and device driver contexts, MFD means Multi-Function Device. This refers to a hardware component that provides several distinct functions through a single physical device. The Linux kernel, for example, uses an MFD framework to expose multiple subdevices (sub-components) managed under one parent device, facilitating modular drivers and shared resources such as power or memory.

On product labeling and documentation, MFD is commonly used to denote the manufactured date, i.e., when a product was produced. The MFD can appear on packaging, labels, or certificates to indicate production timing; it is not a universal standard and may be used alongside other dates like the best-by or expiration date.

Because MFD has multiple meanings across domains, the intended interpretation is typically evident from surrounding context. See also usages in avionics, Linux device drivers, and packaging conventions.
