Plain English Meaning
When teaching a maneuver, the instructor first walks through it slowly, then performs it again at full, normal speed. That second, smooth performance is the roll-out.
Full Definition
In the context of flight instruction and skill demonstration, roll-out refers to the instructor performing a maneuver again at normal speed while explaining each step, after first showing it slowly. It is the second pass of a demonstration, where the action is rolled out fluidly so the student sees how the steps fit together in real time.
Context Anchor
Commonly used during flight training when an instructor demonstrates or talks a learner through turns and heading control.
Derivation
From the everyday sense of 'rolling something out' — unveiling or presenting it in its finished form. After the slow, -down version, the instructor 'rolls out' the full, polished performance.
