1.The term “angle of attack” is defined as the angle between the…
Chord line of the wing and the relative wind
Airplanes Lateral axis and that of the air striking the airfoil
Airplanes centerline and the non-relative wind
Correct Answer : Chord line of the wing and the relative wind
2.Why is frost considered hazardous to flight?
Frost changed the shape of the airfoil
Frost spoils the smooth flow of air over the wings, decreasing lifting capability
Frost slows airflow over the wings
Correct Answer : Frost spoils the smooth flow of air over the wings, decreasing lifting capability
