What term describes the average forward horizontal distance from the cockpit at which prominent unlighted objects may be seen and identified by day and prominent lighted objects may be seen and identified by night?

• A. Flight Visibility
• B. Ground Visibility
• C. Visual Range
• D. Object Sight Distance

Answer: (A)

Flight visibility is the average forward horizontal distance from the cockpit at which prominent unlighted objects may be seen and identified by day and prominent lighted objects may be seen and identified by night. This measure describes what a pilot can realistically see ahead along the flight path and is the standard weather parameter used in flight planning and reports. It differs from ground visibility, which refers to how far you can see objects on the ground from the air, not along the flight path. Visual range is a more general term for visibility distances in some contexts, but in FAA terminology the specific forward-ahead visibility used for flight planning is flight visibility. Object sight distance isn’t a recognized term for this concept.
