What characterizes a Restricted area?

• A. An Area Where Flight Is Absolutely Forbidden
• B. An Area Where Operations Are Hazardous to Nonparticipating Aircraft and Require Permission; May Be Active or Inactive
• C. An Area Used for Maritime Operations
• D. An Area Designated for VFR Corridors

Answer: (B)

A Restricted area is airspace where activities could be hazardous to aircraft that aren’t participating in the operation, so entry isn’t allowed without permission from the controlling authority. It may be active at some times and inactive at others, meaning pilots must check the charted times and obtain clearance if the area is active. The purpose is safety and separation from military or other high-risk activities, such as training or weapons firing.

This isn’t simply “absolutely forbidden” at all times, since permission can allow entry when required. It isn’t for maritime operations, and it isn’t a VFR corridor designation.
