What is the purpose of setting radar displays to the appropriate area of jurisdiction?

• A. To limit communication
• B. To ensure accurate tracking of traffic within controlled airspace
• C. To reduce display size
• D. To hide other sectors

Answer: (B)

Setting radar displays to the area you control makes the radar information you’re working with reflect only the airspace you’re responsible for. This lets you accurately track each aircraft’s position and movement within your jurisdiction, maintain proper separation, and coordinate handoffs with neighboring sectors. If the display included traffic outside your responsibility, you could misread positions or issue instructions based on incomplete or irrelevant data, increasing the risk of conflicts. The goal is to have a clear, accurate picture of traffic you need to manage, not to restrict communications or shrink the display, and certainly not to hide other sectors from awareness.
