How does wind affect the take-off performance? (1,00 P.)
Tailwind aids the aircraft in overcoming the initial drag at the commencement of the take-off roll. The take-off distance will decrease
Tailwind reduces the relative wind on the airfoil. The take-off distance will increase
Headwind causes an increased airflow around the wing. The take-off distance will increase
