Plain English Meaning

It is a digital screen in the cockpit that shows the pilot the key flight information all in one place, instead of using lots of separate round dials.

Full Definition

An electronic flight display (EFD) is a cockpit instrument screen that uses computer-generated graphics to present flight information — such as attitude, airspeed, altitude, heading, and navigation data — on a single integrated display, replacing the individual mechanical gauges found in traditional cockpits.

Context Anchor

Seen in aircraft with glass cockpit systems and in instrument flying discussions about how flight information is shown to the pilot.
