What is required for a drop zone that has more than 20 seconds of green light?

For a drop zone that has more than 20 seconds of green light, it is essential to have a complete control group in place. This requirement stems from the need to ensure safety and coordination during the jump operation. A complete control group is responsible for overseeing the jumpers, managing the drop zone, and responding to any unexpected situations that may arise.

The presence of a complete control group enhances situational awareness and contributes to effective communication among the jumpers and ground personnel. This is particularly important when the green light duration exceeds 20 seconds, as it indicates a potentially prolonged drop zone availability, which can lead to changes in conditions or an increased risk of hazards. Having a control group allows for timely adjustments and ensures the jumpers are briefed and coordinated, thus maximizing safety and mission effectiveness.
