Which factor is a determinant of lift capacity?

Which factor is a determinant of lift capacity?

• A. Wind
• B. Color
• C. Time of day
• D. Music

Answer: (A)

Wind is a determinant of lift capacity because lift from the rotor depends on the air moving over the blades. A headwind increases the relative airflow through the rotor, boosting lift for the same rotor speed and engine power, allowing you to lift more payload. A tailwind does the opposite, reducing lift. Gusts can also create dynamic loading that challenges the ability to hover or lift safely. The other options don’t affect the aerodynamics or the engine’s ability to produce lift, so they don’t determine lift capacity.
