What drop methods go with a door load?

• A. High velocity only
• B. All methods: High, medium, low, and free drop
• C. Low velocity only
• D. Medium velocity and high velocity

Answer: (B)

A door load can be delivered using any drop method because the choice is driven by the cargo’s characteristics and the mission conditions, not by the door itself. High-velocity drops are used when you need rapid clearance from the aircraft and can tolerate the initial surge, which suits heavier or rugged bundles that are properly packaged to take the shock. Medium-velocity drops offer a balance between forward momentum and control, appropriate for mid‑weight loads where you want reliable separation with manageable drift. Low-velocity drops minimize impact forces for lighter or more delicate loads, helping ensure the cargo remains intact upon release and descent. Free drops apply when the payload is very light or when the situation demands the simplest release without any parachute or assist devices, provided the cargo can safely withstand ground impact and still land in the target area. In practice, the most effective option depends on weight, packaging, release height, airspeed, wind, and the desired ground impact—so all methods are applicable to door loads.
