Where is mountainous terrain located according to AFI 11-202V3?

Mountains and mountainous terrain can be found in several regions as outlined in AFI 11-202V3. The correct choice highlights that such terrain exists within the Continental United States (CONUS), as well as in Alaska, Hawaii, and Puerto Rico. This indicates a broad understanding that mountainous terrain is not limited to a specific area but can be found in various locations across both the continental U.S. and its territories.

Understanding that mountainous terrain can exist in these different areas is crucial for flight planning, navigation, and safety procedures. It allows pilots and planners to take into account the unique challenges that mountainous terrains present, such as turbulence, weather variations, and obstacles.

Other options suggest limitations to the locations of mountainous terrain, which does not reflect the comprehensive scope provided in the AFI. For example, stating that mountainous terrain is found only in urban areas or exclusively in mountainous states does not consider the diverse geography of the U.S. territories or even abroad, which may also include mountainous regions.
