Which of the following is NOT one of the GA airports with security regulations in the Washington, DC area?

The correct answer is Pine Bluff, as it is not one of the airports in the Washington, D.C. area with security regulations related to general aviation. The airports that are typically recognized within the vicinity of Washington, D.C., such as College Park, Potomac Airfield, and Washington Exclusive/Hyde Field, all have specific security regulations due to their proximity to national security interests, including the presence of government buildings and agencies.

College Park is known for being one of the oldest continuously operating airports and has close ties to the University of Maryland, while Potomac Airfield and Washington Exclusive/Hyde Field are also situated near critical national infrastructure, thus requiring compliance with heightened security measures. In contrast, Pine Bluff is located in Arkansas and does not fall under the jurisdiction of Washington, D.C. security regulations, making it the correct response to the question.
