Definition
Aircraft instrument systems that present flight data, navigation information, and engine or system status on electronic displays (typically LCD or CRT screens) rather than on individual mechanical gauges. These systems integrate inputs from multiple sensors and computers and show the resulting information on a small number of multifunction screens, usually a Primary Flight Display (PFD) and a Multifunction Display (MFD).
Plain English
The cockpit setup where flight information is shown on computer screens instead of separate round dials. One screen replaces several traditional instruments, and it can show different information depending on what the pilot needs.
Context Anchor
Seen in glass-cockpit aircraft, instrument flying, aircraft systems discussions, and training on how to read and manage electronic cockpit displays.
Derivation
Electronic' indicates the displays are driven by computers and digital sensors rather than mechanical linkages. 'Flight Instrument' refers to the cockpit gauges pilots use to fly the aircraft. The term simply names what these systems are: flight instruments shown electronically.
Why Pilots Care
Improves situational awareness and reduces pilot workload in low-visibility conditions.
Analogy
It is like replacing several separate dashboard gauges in a car with one integrated screen that shows speed, direction, warnings, and system information in one place.
Grounding Statement
When a pilot looks at the main cockpit screen for airspeed, altitude, heading, and aircraft position, they are using an electronic flight instrument system.
Intuition Check
Do not assume “electronic” means automatic or fail-proof. These systems still depend on sensors, computers, displays, and electrical power, and the pilot is still responsible for checking the information.
Example Sentence 1
The aircraft's electronic flight instrument systems display airspeed, altitude, attitude, and heading on a single primary flight display.
Example Sentence 2
In training, students learn to interpret data from Electronic Flight Instrument Systems during simulated instrument approaches.
