What kind of control group is specified for a drop involving two C-130s in trail, with a length of 1800 meters and 15 seconds of green light?

The scenario involves a drop operation using two C-130 aircraft in trail configuration, with specified distances and intervals. In this context, a complete control group is specified when there are multiple aircraft operating simultaneously in close proximity, especially during airdrop operations where precision is crucial for safety and operational effectiveness.

A complete control group allows for enhanced coordination and management of the drop sequence. The coordination ensures that both aircraft can execute their drops without interference or risk of mid-air collision, which is heightened due to the relatively short distance of 1800 meters and the quick 15-second interval. This type of group involves established safety protocols and defined airspace management to maintain a clear and organized drop sequence.

In contrast, a partial control group typically refers to situations where not all elements of the operation are under rigorous management, possibly leading to increased risks. Controlled airspace might imply specific limitations and regulations but does not indicate the strict management required for simultaneous operations like this. Finally, stating that no group is required would overlook the inherent risks associated with multiple aircraft conducting airdrops close together, which necessitates careful control.

The complete control group's designation is essential to ensure that both aircraft follow the planned drop sequence precisely and maintain safety for all personnel involved.
