Scope and Contents
Scope and Contents
This collection consists of sixteen charts that were part of the production process for four-course radio range routings. As the routings shown are outside of the original airway system developed in 1930, it is assumed that these charts represent a substantive expansion of the airway system, rather than a simple updating of existing infrastructure. The following areas are represented in Texas, Mississippi, Alabama, Florida and Louisiana: Big Spring; Corpus Christi; Abilene; El Paso; Dallas, Ft. Worth, San Antonio; Fort Worth; San Antonio; Houston; Birmingham; Tampa; Atlanta; Miami; Mobile; Jacksonville; Shreveport; and New Orleans.

Beginning in the 1930s, visual guidelines for navigation were replaced by the four-course radio range station system. The radio range station emitted a directional signal, forming four beacons aligned with a compass, each defining a course. Pilots listened to the radio receiver and followed the radio beams from station to station along a particular route. This system had a total of 378 stations before becoming phased out during the 1950s
