What is the PI for a CDS drop from a C-130 during the day?

The correct answer is 200 yards from the lead edge for a Container delivery system (CDS) drop from a C-130 during the day. This distance is established based on calculations that consider several factors including the aircraft's speed, altitude, and the parachute's descent rate.

When the CDS is deployed, it is important to ensure that the containers land within a designated area to avoid hazards and ensure the safety and efficiency of airdrops. The 200 yards distance takes into account the average descent trajectory and drift caused by wind, ensuring that the cargo lands within the intended drop zone. This parameter helps to standardize operations and enhance safety during day operations, which can involve visual cues for better placement of the drop zone.

Understanding the required distance for different drop types and conditions is crucial for jumpmasters, as it supports risk management and the effectiveness of the drop.
