small-object search pattern
- small-object search pattern
A five-sided search pattern for finding small objects whose last position is known. The object could be a dinghy or any other object in the sea or in a given area on land. In this pattern, the search is started at the target’s last known position. The helicopter, or a fixed-wing aircraft, flying at a low speed flies downwind for a relatively short distance as determined by prevailing visibility conditions. Thereafter, the aircraft flies at an approximately 72° angle to its original heading for a short period before commencing the turn again toward the last known position. It proceeds for a similar short distance to the other side continuing the same pattern, as seen in the illustration. In this pattern, the most intense search is done at the center of the pattern—the area where the target is most likely to be present.
