Which of the following is NOT one of the three most common devices used by the hoist to extract casualties?

• A. Stokes basket
• B. Jungle penetrator
• C. Sked litter
• D. Hoverjack

Answer: (D)

The main idea is that helicopter hoist rescues rely on three standard tools designed for secure aerial lifting: the Stokes basket, the jungle penetrator, and the Sked litter. These devices are designed to attach to a hoist line, keep the casualty immobilized, and stay stable as you ascend. Hoverjack is a ground-based lifting system that uses an inflatable cushion to move a patient across surfaces or to lift them for ground maneuvers, not integrated for aerial hoist use. Because it isn’t designed for aerial attachment, rigging, or stable ascent in a hoist scenario, it isn’t considered one of the three common hoist extraction devices. In practice, you’d choose among the three standard devices based on the situation—rugged terrain, tight spaces, or quick loading—while hoverjack remains outside the typical hoist extraction toolkit.
