Which of the following is NOT typically included in the definition of airspace required for range operations?

The correct choice refers to civilian airspace, which is generally not included in the definition of airspace required for range operations. During range operations, specific types of airspace are designated to ensure the safety and efficiency of military training and tests. These include military operations areas, restricted areas, and air traffic-controlled assigned airspace, all of which serve specific operational purposes and are managed by military and aviation authorities to prevent conflicts and ensure safety during exercises.

Civilian airspace, on the other hand, is primarily used for non-military aircraft operations, including commercial and private flights. As such, it operates under different regulations and is less focused on the specialized needs of military range operations. This distinction means that while civil airspace is monitored, it does not fall within the typical classifications necessary for military range operations. Therefore, the airspace required for these operations encompasses areas specific to military activities rather than civilian usage.
