Aviation communication systems

TO DISCUSS at any length the many and complex needs of aviation for communications and the varied methods by which these needs may be met would require a great deal more space than is available. Aviation is the largest single industrial user of communications in the United States today. However, it is believed that a reasonably clear picture of the problems and needs may be established briefly and some suggestions may be offered in this article. Aviation is looking anxiously to the radio and electronic industry for the ultimate answer to problems yet unsolved. Until the members of the various communications groups and the manufacturers make available additional equipment in a form which can be used commercially, the needs of aviation for communications and air navigation cannot be fully met.
