How would a fix that is NOT named be described?

A named fix is typically designated with a specific name to facilitate communication and navigation. However, a fix that is not given a name must be described through its relation to a navigational aid (NAVAID) or its specific geographic coordinates.

In the case of a non-named fix, the description usually includes the radial direction and the distance from the NAVAID, followed by the phrase "Mile Fix." This method makes it clear to pilots where the fix is located relative to the NAVAID, using measurable parameters that can be easily understood and referenced during flight operations. This practice enhances situational awareness, ensuring that pilots can accurately navigate without relying on a designated name.

In contrast, other options do not capture the full and proper method of describing a non-named fix. For example, simply referencing a NAVAID does not provide the necessary context of distance or direction. Similarly, merely using radial direction or naming it as a numbered waypoint would lack specificity, which is essential for clear navigation and communication among pilots and air traffic control.
