A stable air mass would most likely have what conditions?
Showery precipitation
turbulent air
Very high temperatures
smooth air
300s - Q8
Why is frost considered hazardous to flight?
Frost slows the airflow over the airfoils, thereby increasing control effectiveness
Frost spoils the smooth flow of air over the wings, thereby decreasing lifting capability
Frost may cause the airplane to become airborne with a lower angle of attack at a lower indicated airspeed
Frost changes the basic aerodynamic shape of the airfoils, thereby decreasing lift
