What restricts air space?

• A. MOA
• B. Restricted airspace
• C. ROZ
• D. Prohibited area

Answer: (C)

Airspace restrictions are put in place to protect ongoing military activities. A ROZ, or Restricted Operations Zone, is a designated area where access is limited and operations are coordinated to reduce risk to other air traffic during specific times or missions. When the zone is active, flying through it typically requires clearance, or you must avoid it entirely, because training, live-fire, or other mission activities are taking place there. This makes the ROZ the specific tool used to constrain airspace for particular operations, more explicit than a MOA (which may allow entry with separation) or a purely restricted or prohibited area (which are fixed in their restrictions). A ROZ is thus the mechanism that restricts air space for the duration and scope of the mission.
