Which of the following statements about air traffic control airways is true?

Airways in air traffic control are established routes used for guiding aircraft during flight, and the statement that these airways may be designated for both commercial and general aviation use is accurate. These airways provide a structured path that aids in navigation and helps ensure safety in airspace by keeping various types of aircraft on a designated route. This inclusivity allows both commercial carriers and general aviation pilots to utilize the same air traffic system, promoting efficiency and safety across all types of aviation.

The other options do not reflect the reality of air traffic control airways: altitude ranges for routes can vary depending on the specific airway and airspace classifications; VOR (VHF Omnidirectional Range) airways are not restricted to Class A airspace but can also exist in Class B, C, D, and E airspace; and jet routes, while traditionally used by larger aircraft, are not exclusive to military operations but are available for civilian use as well. Thus, the correct understanding of airway designations reflects the collaborative nature of air traffic management across various aviation sectors.
