electronic flight information systems
C2Technical / Aviation
Definition
Meaning
A collection of integrated computer systems that provide flight crews with essential operational data, including flight plans, weather, navigation, and aircraft status.
A broader category of digital avionics and ground-based systems used for planning, monitoring, and managing all phases of flight, encompassing communication, navigation, surveillance, and air traffic management data.
Linguistics
Semantic Notes
Almost always used as a singular noun phrase (the system) but refers to a suite of subsystems. It is a hypernym for specific systems like EFB (Electronic Flight Bag) or FMS (Flight Management System).
Dialectal Variation

Differences
No major lexical differences. Acronym 'EFIS' is used universally, but may sometimes be confused with 'Electronic Flight Instrument System' in specific technical contexts.
Connotations
Neutral technical term in both variants.
Frequency
Equally low-frequency and specialized in both UK and US aviation English.

Examples
By Part of Speech
verb
British English
- The engineers are **electronic flight information system-ing** the new fleet. (Non-standard, but illustrative of technical jargon formation)
American English
- The techs are **EFIS-ing** the cockpit as we speak. (Informal technical slang)
adverb
British English
- The data was presented **electronic-flight-information-systems-style**.
American English
- The map updates **EFIS-quick**.
adjective
British English
- The **electronic-flight-information-systems** display was critical for the approach.
American English
- We need an **EFIS** specialist on the maintenance team.
Examples
By CEFR Level
- Modern planes have computers to help the pilots.
- The pilots checked the aircraft's electronic systems for the flight plan.
- The integration of electronic flight information systems has drastically reduced cockpit workload by centralising navigational and meteorological data.
Learning
Memory Aids
Mnemonic
Think: 'EFIS' = Electronic Facts In the Sky.
Conceptual Metaphor
THE COCKPIT IS A COMPUTER WORKSTATION; FLIGHT DATA IS A DIGITAL STREAM.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'электронные полетные информационные системы' in casual speech; it's a highly technical term. The acronym 'EFIS' (ЭФИС) is often used in professional contexts.
- Do not confuse with 'бортовая система информирования', which is more generic.
Common Mistakes
- Using a singular verb (e.g., 'systems is') due to misunderstanding the plural head noun 'systems'.
- Confusing the acronym EFIS (Electronic Flight Instrument System) with the full phrase, which is broader.

FAQ
Frequently Asked Questions
Not exactly. EFIS commonly stands for 'Electronic Flight Instrument System,' which is a specific display component. 'Electronic flight information systems' is a broader term that can include EFIS, Flight Management Systems (FMS), and other data sources.
No. While ubiquitous in modern commercial and business aviation, many smaller, older general aviation aircraft still use traditional analogue gauges and paper-based information.
Primarily flight crews (pilots). Dispatchers, air traffic controllers, and maintenance personnel may interact with related ground-based components of these systems.
They enhance situational awareness and safety by integrating and clearly presenting vast amounts of real-time flight data, reducing pilot workload and the potential for error.
