What is the primary purpose of position fixing in navigation?

• A. To navigate by measuring position relative to a known object
• B. To measure altitude via barometer
• C. To compute fuel consumption
• D. To determine time of day

Answer: (A)

Position fixing is about pinpointing your exact location on the chart so you can navigate accurately. By measuring bearings or ranges to known reference points (such as landmarks, stars, radio beacons, or GPS), you establish where you are on the map. Once you know your position, you can plot it, compare it to your planned route, and determine the proper course and timing to reach your destination. Altitude measurement relates to vertical position, not where you are on the surface. Fuel consumption and time of day are important tools or outcomes, but they aren’t the primary purpose of determining your location.
