Which light pattern has a 7-meter distance between the base light and directional light?

• A. Circle
• B. Inverted Y
• C. T
• D. Cross

Answer: (B)

Understanding how light patterns communicate offset in sling-load setups helps you recognize the exact spacing used. In this context, the base light marks the center, and the directional light is placed along an arm to show the intended lift direction or offset. The inverted Y pattern is designed so the directional light sits about 7 meters away from the base light along one arm, making that specific 7-meter separation clear to the crew.

Circle would have lights arranged around the base in a circle, so there isn’t a single fixed distance between base and a directional light. Cross places lights at the ends of a cross shape, which doesn’t encode a 7-meter base-to-directional distance. T places a directional light at the end of a stem, but that arrangement doesn’t correspond to a 7-meter offset between base and directional light. Thus, inverted Y best matches the 7-meter spacing requirement.
