Pre-flight check: a deliberate, structured review of key
Pre-flight check: a deliberate, structured review of key conditions before execution that externalizes verification to prevent errors from propagating, positioned at the boundary between preparation and execution, requiring observation rather than recall, and containing 5-9 condition-based items that must be independently verified
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'pre-flight check' by identifying its genus (structured verification), differentia (key conditions, externalized verification, positioned at boundary, observation-based, 5-9 items), and distinguishes it from general checklists and ritualistic checking. It captures the core cognitive mechanism and structural requirements described throughout the lesson.
