For a VS search, how is track spacing defined?

• A. +1/2 of the total search radius
• B. The distance between adjacent parallel search legs
• C. Equal to the total search radius
• D. A fixed two nautical miles

Answer: (A)

In a VS search, track spacing is defined as half of the total search radius. This ensures the sensor footprints from adjacent legs overlap enough so the area remains covered as the pattern progresses, without gaps. If you used the full radius, you’d risk gaps between legs; a fixed distance like two nautical miles wouldn’t adapt to the sensor’s range. The distance between adjacent parallel search legs describes the layout but isn’t the formal spacing parameter—the spacing is tied to the sensor’s radius.
