Aeronautical radio communications

In addition to the establishment of beacon lights and intermediate landing fields by the Federal Government, additional communication facilities are being provided which will meet the further demands of air transport companies operating under all conditions of weather on Federal airways. These facilities consist of a network of land line services, airways radio stations, and radio range stations along the airways for collecting and broadcasting weather information and for the guidance of aircraft by radio direction. Marker beacons are located at the intersection of the radio range courses to signal the pilot that his receiver-should be adjusted to the frequency of the next radio range. These beacons also serve to give the exact location on the route. The Bureau of Standards and other similar branches of the Government and private concerns are constantly engaged in research and development work. The Federal Radio Commission´s aviation plan provides for two-way communications with aircraft by the air transport companies. The aviation plan also provides for a system of communications between airports and aircraft. The services of these companies and airports are coordinated with the facilities provided by the Federal Government.
