Definition
Practice deliveries of a lecture or briefing performed in advance of the actual presentation, used to test pacing, content flow, equipment, and delivery before facing real students.
Plain English
Rehearsals. You go through the whole lecture as if it were the real thing, but with no students present, so you can spot and fix problems before it counts.
Context Anchor
In the Aviation Instructor’s Handbook, this term appears in guidance for preparing a teaching lecture, where an instructor practices the lecture with another instructor before presenting it to students.
Derivation
The phrase comes from older military and theatrical use, where a 'dry' run meant a practice attempt without the 'wet' element that made it real -- live ammunition in gunnery, water in firefighting drills, or a live audience in performance. The 'dry' part signals 'practice only, nothing at stake.'
Why Pilots Care
For flight instructors, a dry run reveals weak transitions, timing problems, or technical issues with visual aids before students are sitting in front of them. A smoother lecture means students absorb more and are less likely to walk away confused.
Intuition Check
Do not read “dry” here as meaning “not wet.” In this context, a dry run means a practice version done before the real lecture or operation.
Example Sentence 1
Before teaching the new weather lesson, the instructor did two dry runs with a fellow CFI to refine timing and check the projector setup.
Example Sentence 2
Before teaching the new weather briefing module, she scheduled a dry run to identify any confusing sections.
