Each airway carries its own name, required airspeed, radio and cockpit instrument procedures, operating altitudes, and rules for entering and leaving the airway. The low-altitude Victor Airways run from 700 feet (213 meters) above ground level to 18,000 feet (5,486 meters), while Jet Routes run from 18,000 feet to 35,000 feet (5,486 meters to 10,668 meters). Within these broad groups, all navigation aids such as radio transmission stations, visual and satellite checkpoints, and the responsible control center have names and unique abbreviations. This complex language is printed on pilot charts and in thick directories. Low-altitude airways are shown on the sectional aeronautical chart.
At points where these invisible roadways intersect, radio signals from ground stations mesh to form an electronic picture on cockpit instruments that looks like a road intersection. The Federal Aviation Regulations and air traffic controls set rules for how to cross airways and at what altitude, what intersections to use, and at what angle and speed of flight to enter and leave them.
Airways are for civilian aircraft and airliners. A separate system of airways exists for military aircraft that protects civilian aircraft from the very high-speed military operations and which protects military or government areas from unauthorized flights over their land.
