What statement is most correct regarding coverage effort?

• A. A coverage factor of one is a goal but not always possible
• B. A coverage factor of two is standard
• C. Coverage factor must be three
• D. Coverage factor is never used

Answer: (A)

Coverage effort is about how thoroughly the search area is scanned and how much redundancy is built in to reduce missed areas. The goal is to achieve single-pass coverage, so every location is checked once. In practice, terrain, weather, time, and available resources often prevent a perfect single pass, so planners build in some redundancy or plan for revisits when needed. That’s why this statement—aiming for single-pass coverage as the target but recognizing it isn’t always attainable—is the best description. It isn’t correct to claim there’s a universal standard of a fixed number of passes, and coverage factors are indeed used in planning to guide how much effort to invest, not to say they are never used.
