Which combination is used to express any location on a chart?

• A. Latitude and longitude
• B. Altitude and longitude
• C. Speed and bearing
• D. Distance and course

Answer: (A)

Expressing any location on a chart relies on a global coordinate system. Latitude and longitude provide that framework: latitude measures how far north or south you are from the equator, while longitude measures how far east or west you are from the Prime Meridian. When combined, they pinpoint a unique point anywhere on the Earth's surface, using either degrees-minutes-seconds or decimal degrees. Other options mix in height, motion, or a path rather than a fixed point, so they don’t reliably identify a single location on a chart.
