Which factor is NOT a weather factor influencing air assault planning?

• A. Wind speed/direction
• B. Visibility
• C. Ocean currents
• D. Temperature

Answer: (C)

Weather factors for air assault planning are atmospheric conditions that affect aircraft performance and flight safety. Wind speed and direction influence rotorcraft lift, hover, ground speed, and maneuverability. Visibility determines how well pilots can detect terrain, obstacles, and landing zones, especially in adverse lighting or degraded visual conditions. Temperature affects air density, which in turn impacts engine performance, rotor efficiency, and overall aircraft performance at a given altitude. Ocean currents describe the movement of water in the oceans and seas; they affect maritime operations and sea state, not the atmospheric conditions the aircrew must contend with. So ocean currents do not constitute a weather factor for air assault planning.
