What distinguishes warning areas from restricted areas?

The correct answer highlights that warning areas do not have U.S. jurisdiction over them, which differentiates them from restricted areas. A warning area is a specific type of airspace that may contain hazards to non-participating aircraft but does not restrict access to that airspace. It is typically associated with military operations over international waters or certain other areas but does not imply that the U.S. government can control all activities within the airspace.

Restricted areas, on the other hand, are designated airspace where flight is prohibited or restricted due to unusual, often hazardous, activities such as live-fire exercises or other military operations. While they are charted and they can be established by military authorities, they are firmly under U.S. jurisdiction, and actions taken within them are controlled according to specific regulations.

The other options do not accurately reflect the characteristics of warning and restricted areas. For example, warning areas are generally charted on aeronautical maps, so that option does not hold true. Additionally, while restricted areas might often be associated with military control, they can be established for civil operations as well. Lastly, stating that warning areas are limited to domestic flight only overlooks the fact that they can extend over international waters, where different jurisdictional considerations apply.
