This revision of "Aeronautical Science Course of Study for California High Schools," first issued in 1967, is designed by and for the use of teachers of high school aeronautical courses. It differs from other aeronautical instructional materials in its emphasis on inquiry, exploration, and open-ended experimentation. The eleven units may be used separately or as an entire course. The first nine units, designed for thirty-six weeks of classroom study, include: basic aeronautics, meteorology, navigation, FAA regulations, speed of sound, physiology of flight, man in space, history of aviation, and economic factors. The last two units deal with actual flight training. Lists of films and publications are provided. (RS)
