What is the definition of Minimums in flight events?

• A. Weather conditions restricting take-off or landing
• B. The minimum number of crew required on board
• C. Minimum fuel on board
• D. Minimum cabin temperature

Answer: (A)

Minimums in flight events are the lowest weather conditions that must be present to permit take-off or landing. They set the required visibility and cloud ceiling (and, for some approaches, runway visual range) that must be met for operations to proceed. If the weather is below these thresholds, take-off or approach/landing cannot be conducted and alternatives like delaying, diverting, or canceling are considered. The other options describe different limits (crew numbers, fuel, or cabin temperature) and are not the definition of minimums for take-off or landing.
