Restricted area is airspace designated under 14 CFR Part 73 within which the flight of aircraft is subject to restriction. Which description best fits this designation?

• A. Airspace designated under 14 CFR Part 73 within which flight is subject to restriction
• B. Flight is completely prohibited in this airspace
• C. Airspace reserved for military training routes
• D. Warning areas only

Answer: (A)

Restricted areas are airspace designated under 14 CFR Part 73 where entry is not unrestricted and the flight of aircraft is subject to restrictions. The core idea is that these areas exist to protect people and activities from hazards associated with certain operations, such as military testing or weapons activities, so pilots must obtain authorization before entering and must comply with any time, altitude, or procedure restrictions. This isn’t an absolute prohibition; authorization can be granted by the controlling agency, and the restrictions can vary by area and time, as shown on charts and NOTAMs. It’s different from military training routes, which are specific low-level corridors for military training, and from warning areas, which are offshore areas intended to warn nonparticipating pilots of potential danger rather than define a general restriction.
