Which statement best describes the category of airspace known as special use airspace?

• A. Prohibited, restricted, warning, military operations, and alert areas
• B. Open airspace
• C. Unrestricted airspace
• D. Controlled airspace

Answer: (A)

Special use airspace is designated for activities that could be hazardous to aircraft not directly involved, so access and flight rules are specifically restricted or warned. The categories included are Prohibited areas (flight is not allowed), Restricted areas (flight is allowed only with authorization), Warning areas (potential hazards over international waters), Military Operations Areas (military training that can affect other aircraft), and Alert areas (high volumes of training activity). This is why the statement listing Prohibited, Restricted, Warning, Military Operations Areas, and Alert Areas best describes special use airspace. Open, unrestricted, or standard controlled airspace describe other classifications and don’t capture these protective regions.
