What is necessary to achieve the proper drag surface for external loads?

• A. Level, heavy weight, proper link count
• B. Aerodynamic, level, proper link count
• C. Flat, heavy weight, adjusted air speed
• D. Compact, light weight, strategic link count

Answer: (B)

To achieve the proper drag surface for external loads during air assault operations, it is essential to consider aerodynamics, maintaining a level position, and having the proper link count. Aerodynamics is crucial because the design of the load and how it interacts with airflow directly affect drag. Loads should be shaped or positioned in a manner that minimizes turbulence and maximizes stability during flight. A level position ensures that the load remains stable and correctly aligned with the rotor wash and airflow, thereby reducing unnecessary drag. The proper link count refers to the specific number of links used in rigging the load, which can influence how the load reacts to aerodynamic forces. It plays a significant role in ensuring that the load is both balanced and secure, contributing to overall safety and efficiency during transport. The combination of these factors—being aerodynamic, level, and having the correct link count—optimizes performance and ensures that the load can be transported safely and effectively by the helicopter.
