An inexpensive method of training for student pilots learning radio orientation as associated with “blind” flying has been made available through development of a compact radio-signal instrument designed for ground instruction. Approved by American and British air force officers, airline pilots, instructors and students, the Orientator aids the student in acquainting himself with the numerous signal blends found in “flying the beam,” thus reducing by about 75 percent the four to eight hours of flight training usually required.
