What is the difference between an airway endpoint and a fix?

• A. An endpoint is a distance along the airway; a fix is a named terminus.
• B. An endpoint is a VOR or named terminus of the airway; a fix is a defined point along the route used to connect airways.
• C. An endpoint is a VOR frequency; a fix is an altitude reference.
• D. An endpoint is the midpoint of the airway; a fix is the end.

Answer: (B)

Airway endpoints are the anchors that define where an airway starts and ends, and they are usually navigation aids like a VOR or another named terminus. A fix, by contrast, is a defined point along the route used to connect airways—an interior waypoint or intersection that lets you move from one airway segment to another. In practice, you fly from one endpoint to another, with fixes arranged in between to link different airways and form the route network. The distinction is that endpoints mark the ends of an airway, while fixes are the internal points that connect airways together.
