A predetermined geographical position used for route/instrument approach, progress reports, published VFR routes, etc., defined relative to a VORTAC station or in terms of lat/long coordinates.

• A. Waypoint
• B. Fix
• C. Intersection
• D. Node

Answer: (A)

Waypoints mark fixed geographic positions used for navigation on routes, instrument approaches, progress reporting, and published VFR routes. They can be defined by precise latitude/longitude coordinates or anchored relative to a navaid like a VORTAC, which lets the same point be used across different navigation systems, including GPS/RNAV. This flexibility and broad applicability make waypoints the standard reference point for planning and executing routes and procedures. A fix is a navigation position as well, but it’s a more generic term often tied to the crossing of radials or other navaid geometry; an intersection is a specific type of fix defined by the crossing of two radials; a node isn’t a standard aviation term for these navigation points.
