84 The Day Trade Preparatory Courses are of two types: the Type A or the Type B Trade Courses. The Type A Trade Course is one in which the related subjects are taught in segregated classes apart from the practical shop work. In courses of this type, fifty per cent of the school time, which must be not less than three consecutive clock hours in one day, and not less than fifteen hours a week, is given to "practical work on a useful or productive basis," and a minimum of twenty-five per cent of the school time to related subjects. The balance is given to general subjects. The time used may exceed the standards which are stated. A total of thirty clock hours of instruction a week must be carried. The Type B Trade Course is one in which the related instruction is given by the shop teacher, incidental to the shop instruction, with no separation of the total time into definite periods for the teaching of related subjects. In such courses, fifty per cent of the school time, which must not be less than fifteen hours a week, is given to the combination of shop and technical instruction. The balance of the school day, or thirty hours a week, is devoted to general and related subjects. The time used may exceed the standards here stated. Department of Aircraft Engine and Repair The courses listed in the Department of Aircraft Engine and Repair are for training a transfer or a terminal student interested in the construction, repair, and service of light aircraft. The training meets standards of Type A and Type B programs. The Department is equipped to meet Civil Air Regulations, and to give training that will enable a student to meet the requirements for an advanced aircraft and engine mechanic.
