Which combination correctly describes a typical VS search?

Which combination correctly describes a typical VS search?

• A. First leg in the direction of the object's drift; turn 120 degrees to the right; track spacing +1/2 of the total search radius
• B. First leg opposite the object's drift; turn 90 degrees to the left; track spacing +1 nm every two legs
• C. First leg in the direction of the object's drift; turn 90 degrees to the right; track spacing equal to the total search radius
• D. First leg perpendicular to drift; turn 60 degrees; track spacing +1/4 of the radius

Answer: (A)

In a VS search, you plan the path to ride with the probable movement of the object and sweep the area with overlapping passes. Starting the first leg in the direction the object would drift keeps your search path aligned with where the object is likely to be carried, so the pattern stays relevant to the target’s possible path. Turning 120 degrees to the right after that creates three legs that are evenly spaced around the search area, forming a triangular pattern that evenly covers the vicinity of the last known position. Setting track spacing to half of the total search radius ensures adjacent passes overlap enough that there are no gaps between swaths as you work outward, which is essential for reliable visibility in a drifting environment. Other options don’t fit this approach because they either ignore drift in the initial leg or use turns that don’t produce the same uniform, overlapping coverage, or they specify spacing that’s either too large or not aligned with the intended coverage geometry.
