What type of lights help indicate that an aircraft stand is occupied?

Green taxi line lights are specifically used to indicate that an aircraft stand is occupied. These lights are located along the taxi lines and are part of the visual aid system that guides pilots and ground controllers. When green lights are illuminated, it signals to operators and pilots that the stand is currently in use, which helps prevent any potential safety hazards associated with moving aircraft.

Understanding the function of these lights is crucial for airside operations. Ground personnel must be aware that if the green lights are visible, they should not attempt to direct another aircraft to the same stand, thereby ensuring safety and preventing any accidents or miscommunication on the airfield. The proper functioning and observation of these lights are essential for maintaining efficient and safe operations at the airport.
