What drop method can you use for gravity?

• A. Only gravity
• B. Free drop
• C. None of the above
• D. All except for free drop

Answer: (D)

When you rely on gravity to deliver a load, gravity is the driving force, but you still need a method that controls how the descent happens. Most drop methods add stabilization, timing, or deployment devices so you can steer or slow the load for a safe landing. Free drop means releasing with no stabilization or deceleration mechanism, resulting in an uncontrolled, unregulated fall. Because of that lack of control, free drop isn’t a usable option when planning gravity-based deliveries. So gravity can be used with all the other drop methods that provide control, but not with pure free drop.
