A '''Multi-function display''' (MFD) (part of [[Multi Function structure]]s) is a small screen ([[cathode ray tube|CRT]] or [[LCD]]) in an [[aircraft]] surrounded by multiple [[soft key|buttons]] that can be used to display information to the [[aviator|pilot]] in numerous configurable ways. Often an MFD will be used in concert with a [[Primary flight display|Primary Flight Display]]. MFDs are part of the digital era of modern planes or helicopter. The first MFD were introduced by air forces. The advantage of an MFD over analog display is that an MFD does not consume much space in the cockpit. For example the cockpit of [[RAH-66|RAH-66 "Comanche"]] does not have analog dials or gauges at all. All information is displayed on the MFD pages. The possible MFD pages could differ for every plane, complementing their abilities (in combat).

A '''multifunction display''' ('''MFD''') is a small-screen ([[cathode-ray tube|CRT]] or [[LCD]]) surrounded by multiple [[soft key]]s (configurable buttons) that can be used to display information to the user in numerous configurable ways. MFDs originated in aviation, first in military aircraft, and later were adopted by commercial aircraft, [[general aviation]], automotive use, motorsports use, and shipboard use.

Many MFDs allow the pilot to display their navigation route, moving map, weather radar, [[NEXRAD]], [[Ground Proximity Warning System|GPWS]], [[Traffic Collision Avoidance System|TCAS]] and airport information all on the same screen.

== MFDs in aviation ==

MFD's are added to the [[Space Shuttle]] (as the [[glass cockpit]]) starting in 1998 replacing the analog instruments and CRT's. The information being displayed is similar, and the glass cockpit was first flown on the [[STS-101]] mission.

The advantage of an MFD over analog display is that an MFD does not consume much space in the cockpit, as data can be presented in multiple pages, rather than always being present at once. For example, the cockpit of [[RAH-66|RAH-66]] "Comanche"]] does not have analog dials or gauges at all. All information is displayed on the MFD pages. The possible MFD pages could differ for every plane, complementing their abilities (in combat).

MFD in automotive community refers to the usage of these small screen display in modern cars with information about the Multimedia,Navigatoin, Vehicle status etc. These echnology started with the luxury car segments and now spreded in to the medium

and low end cars. The MFD unit in the car look like an extra attachment to the Audio Unit or with the Audio unit itself. In moden

cars you can browse through the songs list that is attached in to the MFD (CD,USB,IPOD, Bluetooth phone),even you can dial number

the person's phone from the stores contact using the MFD console and adjust your vehicle clock time and lot more.

MFDs were added to the [[Space Shuttle]] (as the glass cockpit) starting in 1998, replacing the analog instruments and CRTs. The information being displayed is similar, and the glass cockpit was first flown on the [[STS-101]] mission. Although many corporate business jets had them in years prior, the piston-powered [[Cirrus SR20]] became the first [[type certificate|part-23 certified]] aircraft to be delivered with an MFD in 1999 (and one of the first general aviation aircraft with a 10-in, flat-panel screen), followed closely by the [[Columbia 300 (aircraft)|Columbia 300]] in 2000 and many others in the ensuing years.

The voice recognizition module attached to this will have user interaction to get the voice command and it will prompt to the commanded action either to play a particular song,make call to particular person or type a text message as told by the user.

In modern automotive technology, MFDs are used in cars to display navigation, entertainment, and vehicle status information.
