What defines Special Use Airspace (SUA)?

Special Use Airspace (SUA) is defined as airspace of defined dimensions where activities must be confined due to their nature. This type of airspace is established to support specific activities that may be hazardous to nonparticipating aircraft or where the nature of the activity requires separation from other air traffic. Examples of activities that might lead to the designation of SUA include military operations, aerial gunnery, or other activities such as parachuting, which require certain restrictions on air traffic in order to ensure safety.

The clear delineation of \SUA\ facilitates better airspace management and promotes safety both for the aircraft involved in those specific operations and for the general aviation community.

The other options suggest characteristics that do not align with the defined purpose of Special Use Airspace, such as unrestricted access for all users, which does not apply to SUA. Similarly, airspace designated specifically for scheduled commercial flights does not pertain to the unique restrictions and nature of SUA, and exclusive reservation for military training does not encapsulate all types of activities that could fall under SUA.
