What is a geographical position determined by a fix, an azimuth from the fix, and a distance from the fix called?

The term that describes a geographical position determined by a fix, an azimuth from that fix, and a distance from the fix is known as Fix Radial Distance (FRD). This concept is crucial in navigation and involves using a known point (the fix) and the direction (the azimuth) along with a specific distance to pinpoint a new location in space. This method is often used in both aviation and maritime navigation to establish positions relative to landmarks or navigation aids.

The correct choice highlights the relationship between the fix and the angular direction in combination with the distance, thereby allowing for a precise calculation of the new position based on these navigational elements. Understanding this concept is vital for effective navigation and situational awareness in the field.
