Definition
A training or briefing setup that combines sound and pictures — such as recorded audio paired with slides, video, or projected images — to present instructional material to a student or group.
Plain English
A teaching tool that uses both what you hear and what you see at the same time, so the lesson is easier to take in and remember.
Context Anchor
Seen in aircraft warning systems, cockpit displays, training equipment, and passenger information systems.
Derivation
From Latin 'audire' (to hear) and 'visus' (sight). The combined word simply means 'hearing-and-seeing,' which captures exactly what the system delivers.
Why Pilots Care
A lot of early flight training — weather, systems, regulations — is delivered through audiovisual material. Knowing the term keeps you oriented when an instructor or syllabus refers to it.
Intuition Check
Do not think of “audiovisual” only as movies or entertainment equipment. In aviation, it can mean any system that gives information by both sound and sight.
Example Sentence 1
The ground school used an audiovisual system to introduce the basics of weather theory before the classroom discussion.
Example Sentence 2
Passengers adjusted volume on the audiovisual system using controls at their seats.
