    This paper deals with the aid of radio to an air transport operator; first, with merely long-wave receiving equipment on the plane, and, secondly, with the additional use of a short-wave plane transmitter. The tendency is noted toward establishment of short-wave two-way communication systems by theoperators themselves, Requirements for apparatus under these conditions are discussed.

    This paper deals with methods for aligning the courses of the visual radio range with the fixed airways. It has previously been shown that the courses of the aural radio range may be shifted by the use of a vertical wire antenna in conjunction with the transmitting loop antennas or by varying the relative power in the two antennas. These methods are, in part, applicable to the visual system. In th... View full abstract»

    The work gives a review of the present status of radio in aeronautics in Germany. Not only does it describe the apparatus used at the present time in German aircraft communications, but it also gives results of measurements on the fundamentals of radio in aeronautics, which have been made by the Deutschen Versuchsanstalt fiur Luftfahrt E. V. Further, it indicates the trend that German aircraft rad... View full abstract»

    This paper constitutes a report on the results of the measurement of the trailing antenna constants on several types of aircraft including the dirigible Los Angeles. A brief description of the apparatus and method is given. Curves for a typical airplane and dirigible are presented and from these curves conclusions are drawn as to the center of radiation and the relation between antenna resistance ...

    The investigation described below was carried out for the purpose of comparing the transmission characteristics from an airplane of horizontally and vertically polarized waves in daytime. A frequency of about 6 megacycles was arbitrarily chosen. In view of the fact that modern practice is tending towards the elimination of the trailing wire antenna, an antenna producing vertically polarized waves ... View full abstract»

    Measurements of temperature rise of generator under load are given for still air and in flight. Theory of heat emission is briefy reviewed, constants of emissivity are given from which rising and final temperatures of generators can be approximated. Conditions governing the rating of wind-driven aircraft radio generators are discussed. View full abstract»

    In pursuance of the program of radio aids to flight undertaken by the Department of Commerce, experimental and installation work has progressed in the application of the radio range (directive radiobeacon) along the airways. To date, only the aural type has been put into routine daily operation, and it is the only type of beacon considered in this paper, which discusses methods of adjusting the sp... View full abstract»
