Definition
A type of cockpit instrument display that presents information as numerical values or discrete characters (digits, letters, or symbols) rather than as a moving pointer on a graduated scale.
Plain English
A readout that shows information as actual numbers on a screen, instead of using a needle pointing at a dial.
Context Anchor
Seen on aircraft radios, navigation units, engine monitors, and modern cockpit screens.
Derivation
From Latin 'digitus' meaning finger -- the same root as the digits people first counted on their hands. A 'digital' display shows information as digits (numbers), as opposed to an 'analog' display which shows information by analogy, using the position of a pointer.
Why Pilots Care
Gives precise, instantly readable numbers that reduce reading errors during high workload phases such as takeoff, approach, and instrument flight.
Analogy
A digital display is like a digital clock: it tells you “10:30” directly instead of making you interpret the positions of clock hands.
Intuition Check
Digital does not automatically mean more accurate. It means the information is shown as numbers, letters, or symbols; accuracy depends on the instrument and its sensing system.
Example Sentence 1
The fuel quantity now appears on a digital display showing pounds remaining, replacing the older needle gauge.
Example Sentence 2
The pilot cross-checked the digital display for exact airspeed before beginning the approach.
