What is the impact of a headwind on takeoff performance for an aircraft at a weight of 2,900 lb?

A headwind positively impacts takeoff performance by decreasing takeoff distance. This occurs because a headwind provides additional airflow over the wings at lower ground speed, allowing the wings to generate lift more efficiently. As a result, the aircraft can reach the required takeoff speed more quickly and take off in a shorter distance compared to flying in calm or tailwind conditions.

With a headwind, the aircraft's true airspeed increases relative to the surrounding air, even though the aircraft must still reach a specific indicated airspeed for takeoff. Therefore, thanks to the aerodynamic benefits provided by the headwind, the aircraft requires less runway to become airborne, hence leading to a decrease in takeoff distance.
