What should be the direction of the first search leg?

• A. In the direction of the search object's total drift vector
• B. Perpendicular to the drift vector
• C. Opposite to drift
• D. Along a fixed compass heading

Answer: (A)

Drift must be accounted for when searching for a drifting object. The total drift vector combines wind and current and shows the direction the object is expected to move over the surface. Directing the first search leg along that drift vector places your path on the line where the object is likely to be, increasing the chance of detection as the object drifts. Heading perpendicular ignores the object’s movement and likely misses it; heading opposite would chase away from its trajectory; a fixed compass heading disregards drift entirely and reduces effectiveness. By aligning the initial leg with the drift, you’re effectively leading the search to where the object will be, allowing better coverage of its likely path.
