Abstract: With the advent of Loran as an aid to navigation, it became necessary to teach the operation of this subject in the laboratory and classroom. The Loran system was developed during the war and is now used extensively. Training in this method of navigation was rather haphazard at first; the student was told how to operate the set and what to expect. A Loran laboratory was set up and classes were scheduled for evenings when it was possible to receive the sky waves. Some time later, a pulse generator was developed which simulated the steady ground waves and could be controlled as to repetition rate and time difference.But this type of training created a condition whereby the average navigator thought that he had no more worries-that he need merely turn on the set, match the signals and there he was. If this were only true navigation would have been licked. All that would be necessary for navigational operations would he plenty of transmitting stations. Consequently, it was necessary to take students out on flights and show them just what can be encountered and how to interpret the patterns on the scope.
