This self-paced, individualized course, adapted from military curriculum materials for use in vocational and technical education, teaches students the skills needed to become a qualified avionics worker on the HH-3F helicopter. The course materials consist of three pamphlets: two student workbooks and a composite ground/flight syllabus. Each assignment in the first two pamphlets is divided into three parts: the reading assignment and objectives, the reading material, and the self-quiz with accompanying answers and text references. Subjects covered in the HH-3F avionics pamphlet are HH-3F helicopter systems, engine and rotor systems, helicopter transmission and other systems, flight systems, communication systems, navigation systems, Loran C Navigator, flight director systems, electronic flight aids, and avionics worker duties. The second pamphlet covers flight preparation, emergency procedures and equipment, hoisting, rescue platform and cargo sling procedures, and high-intensity searchlight system. The third pamphlet is a standardized syllabus designed to give the students training to become proficient and safety-conscious avionics aircrew workers. Materials are illustrated with line drawings.
