Flight Chart for the American Southwest -- Early Appearance of VOR airway Beacons
A fine chart produced by the Department of Commerce for civilian aviation in the early 1950s. The chart is informative, featuring the location of aerodromes, radio towers, radar stations, and restricted flight areas. This information helped civilian aviators navigate the increasingly militarized skies of the country with a better understanding of certain locations where they will be expected to fly a certain way (such as the air defense identification zones). The additional information for locations key for navigation also helps aid any aviator attempting to fly in the area.
The chart is also topographic with the elevation of areas noted to aid those flying. To further aid navigation the map also depicts the locations of major cities and their associated airports, such as San Francisco and SFO, Los Angeles and LAX, San Antonio and SAT, as well as Kansas City and KCMO. The inclusion of all this information makes for an informational chart for any commercial or civilian pilot attempting to fly in the area. Overall a very nice chart that shows the rise of private and commercial aeronautics in the 1950s.
Very high frequency omni-directional range (VOR) is a type of short-range radio navigation system. VOR enables aircraft to determine position and maintain a course by receiving signals transmitted by a network of ground radio beacons. Developed in the United States beginning in 1937, VOR was deployed by 1946 and became the standard air navigational system in the world until the advent of satellite / GPS systems in the 21st Century.
