An airway is based on a centerline that extends from one navigation aid or intersection to another navigation aid (or through several) and is used to establish a known route for en route procedures between terminal areas.

• A. True
• B. False
• C. It is used only for VFR routes
• D. It is used to define terminal area procedures

Answer: (A)

Airways are predefined routes in the airspace that provide a consistent path between navigation aids or fixes. They’re built around a centerline that extends from one navigation aid (like a VOR or NDB) or a designated intersection to another (or through several), so pilots can fly a known, predictable route for en route navigation between terminal areas. This structure supports ATC separation and efficient routing on IFR flights, giving pilots a defined corridor to follow as they move from one area of terminal airspace to another. In the U.S. context, low-altitude airways (Victor airways) follow VOR radials between VORs, while high-altitude airways (Jet routes) work similarly at higher altitudes. This concept is about IFR routing rather than VFR navigation, and airways themselves aren’t the procedure used to define terminal area operations—that role is filled by procedures like SIDs and STARs, though those routes may connect to and through airways.
