Do you have trouble remembering your alto from a cirrus? Do you say nimbo when you mean nimbus? You're not alone. This film will clear up all that confusion. Here you'll learn the ten basic cloud types and their distinct shapes, shades, and altitudes. This film will identify these clouds with their symbols; show their altitudes; show how, when, and where they develop; describe their principle characteristics; and discuss their flight hazards, if any. With easy to understand weather theory and animation this film is a natural complement to both the private pilot and instrument pilot ground school courses.
