Which chart is specifically used for air navigation?

• A. Strip camera
• B. Isoplets
• C. Parallels
• D. Aeronautical chart

Answer: (D)

Air navigation relies on a chart designed specifically for aviation, one that organizes information pilots need to plan and follow a flight safely. An aeronautical chart includes air routes and waypoints, navigational aids (like VORs and NDBs), controlled and special-use airspace, airports, terrain and obstacle data, and communications frequencies, all laid out in a way that supports accurate route planning and situational awareness during flight. This specialized format makes it the go-to reference for flying, as opposed to other options. A strip camera is used to capture ground imagery for map creation, isopleths show lines of equal value such as elevation or other data but aren’t tailored for navigation, and parallels are merely lines of latitude that don’t provide the full navigational context needed for flight planning and execution.
