Plain English Meaning

A short talk before a lesson where the instructor explains what will happen, what the student needs to do, and how performance will be judged.

Full Definition

In an instructional setting, short discussions held before a training session in which the instructor outlines what will be covered, what the student is expected to do, and what standards will apply. Preflight briefings prepare the student to participate actively in the lesson and ensure both instructor and student share the same expectations before flight or ground training begins.

Context Anchor

Student pilots encounter preflight briefings before training flights, check rides, and some normal flight operations where the pilot and instructor or crew need a shared plan.

Derivation

‘Pre-’ comes from Latin meaning ‘before,’ and ‘brief’ comes from Latin ‘brevis’ meaning ‘short.’ A briefing is literally a short, focused talk given before something happens — in this case, before the training session begins.
