What is the primary function of radar systems in air traffic control?

• A. To provide weather forecasts.
• B. To monitor air traffic and ensure safety.
• C. To communicate directly with pilots.
• D. To record flight plans.

Answer: (B)

The primary function of radar systems in air traffic control is to monitor air traffic and ensure safety. Radar systems are essential tools used by air traffic controllers to detect, track, and guide aircraft in the airspace. They provide real-time information on the position, altitude, speed, and direction of all aircraft within their radar coverage. This information allows controllers to maintain safe distances between aircraft, manage departures and arrivals at airports, and coordinate movements in busy airspace. By using radar systems, ATC can effectively minimize the risk of mid-air collisions and facilitate the seamless flow of air traffic, which is crucial for maintaining safety in aviation operations.

The other options serve different functions: weather forecasts are important for flight planning but are not the main role of radar; direct communication with pilots is typically conducted through radio systems; and while recording flight plans is vital for planning and tracking, it is not a primary function of radar systems.
