When must the DZSO or DZSTL communicate with the Drop Zone Control Officer (DACO)?

The requirement for the Drop Zone Safety Officer (DZSO) or Drop Zone Support Team Leader (DZSTL) to communicate with the Drop Zone Control Officer (DACO) is based on ensuring that all parties involved in the aerial operation have adequate time to confirm and coordinate essential details. Communicating 1 hour prior to drop time allows for a thorough review of the drop zone conditions, safety checks, and any last-minute adjustments that may be necessary to ensure a safe and effective drop. This timeframe facilitates a more structured and organized approach, helping to mitigate potential risks associated with the drop.

The other options do not provide sufficient time for comprehensive communication and adjustments. For instance, communicating 15 or 30 minutes before the drop may not allow enough time to address any unforeseen circumstances or to resolve potential safety concerns, which could impact the safety of the jumpers or the success of the mission. Thus, the standard of 1 hour aligns with best practices in military operations, highlighting the importance of thorough preparation and coordination.
