What is the focus of 14 CFR Part 1542?

The focus of 14 CFR Part 1542 is on airport security. This regulation outlines the requirements for security programs at airports, ensuring that they meet the standards necessary to protect against threats and enhance safety for passengers, employees, and airport operations. It establishes the framework for security measures that must be implemented by airports, including access control, employee screening, and responses to security incidents.

In the context of the other options, aircraft performance standards are governed by different regulations aimed at ensuring aircraft are capable of safe operation. Air traffic control procedures are addressed under separate parts of the Federal Aviation Regulations that focus on the safe and efficient movement of aircraft in the airspace system. Noise abatement strategies pertain to regulations meant to minimize noise pollution resulting from aircraft operations but fall under different sections that are not specifically about security. Thus, the distinct emphasis of 14 CFR Part 1542 on airport security makes it the correct answer.
