Why is frost considered hazardous to flight?
A)Frost disrupts the smooth flow of wind over the wing causing reduced lift.
B)It increases the weight of the aircraft and changes the weight and balance.
C)Frost changes the basic aerodynamics of the airfoil, thereby causing reduced lift.
D)There is no hazard only ice on the wings cause a hazard.

Frost disrupts the smooth flow of the wind over the wing causing reduced lift. Frost is just as dangerous as ice as it changes the smooth flow of air over the wing or airfoil. It affects the aerodynamics of the airfoil, but doesn't change it. Frost can add weight to the plan but is not as dangerous as the change in the smooth flow of air.
