How can the scan width of a Bravo scan radar be adjusted?

• A. By maintenance crew on the ground
• B. Using a separate display
• C. In the cockpit
• D. Via a ground control station

Answer: (C)

The scan width is adjusted from the cockpit because radar settings are operated directly by the pilot or radar operator during flight. The cockpit control panel provides the interface to change how wide a sector the radar sweeps, allowing quick adaptation to different situations—narrow for focused, high-detail scanning ahead or wide to cover more area at once. Ground crews or a separate display aren’t used to make real-time changes while the aircraft is in operation, and a ground control station isn’t the venue for adjusting cockpit-based radar parameters. Keeping the adjustment in the cockpit ensures immediate, in-flight control of the radar’s coverage.
