What is the role of slingload reference lights relative to the main marking light pattern?

• A. They are used with the main marking light pattern only when the aircraft has a slingload
• B. They replace the main marking light pattern
• C. They are used only in daylight
• D. They are never used

Answer: (A)

Slingload reference lights are added to the lighting setup specifically to mark the load and provide a precise reference for the crew during hooking, lifting, and positioning. They work in tandem with the main marking light pattern rather than replacing it. The main pattern keeps the aircraft visible and oriented, while the slingload reference lights give ground crews and the helicopter a clear indication of where the load sits and how it’s oriented. These reference lights are only used when a slingload is being carried, and they aren’t needed when there’s no slingload.
