Definition
Flight and engine information presented electronically as numeric readouts or computer-generated graphics on a screen, rather than through mechanical pointers moving on a fixed dial face. In modern aircraft, digital instrumentation typically appears on a Primary Flight Display (PFD) and Multi-Function Display (MFD), where airspeed, altitude, attitude, heading, and engine data are drawn by software based on sensor inputs.
Plain English
Aircraft information shown on screens using numbers and computer-drawn images, instead of on round dials with moving needles.
Context Anchor
Seen in discussions of modern instrument panels, glass cockpit displays, and the transition from round-dial instruments to electronic flight displays.
Derivation
Digital comes from the Latin digitus, meaning finger — fingers were used for counting, so digital came to mean anything based on discrete numbers. In this context it means the information is processed and shown as numerical data on a screen, rather than as a continuous physical movement of a needle.
Why Pilots Care
Delivers clearer, more integrated information that reduces workload and improves situational awareness compared with separate analog instruments.
Intuition Check
Digital instrumentation does not mean the airplane flies itself. It means the information is handled and displayed electronically.
Example Sentence 1
The new training aircraft uses digital instrumentation, so the airspeed appears as a moving tape on the screen rather than as a needle on a round gauge.
Example Sentence 2
Upgrading to digital instrumentation required the pilot to adapt to new display formats during instrument approach training.
