What tool do air traffic controllers primarily use to track aircraft positions?

• A. Flight manuals
• B. Radar systems
• C. Weather balloons
• D. Passenger communication devices

Answer: (B)

Air traffic controllers primarily use radar systems to track aircraft positions because these systems provide real-time information about the location, altitude, and speed of aircraft in the airspace. Radar technology allows controllers to monitor multiple aircraft simultaneously, ensuring safe distances are maintained between them and that they follow the correct flight paths.

Both primary and secondary radar systems play crucial roles in air traffic management. Primary radar can detect any object in its range, reflecting radar waves off the aircraft, while secondary radar relies on transponders onboard the aircraft, which provide more detailed information, such as identification and altitude.

Flight manuals, weather balloons, and passenger communication devices do not serve the main purpose of tracking aircraft positions. Flight manuals are resources for operational procedures and regulations, weather balloons provide meteorological data rather than tracking information, and passenger communication devices are used for communication with passengers rather than for air traffic control functions.
