What is one of the main factors that the FAA inspects in commercial service airports?

The Federal Aviation Administration (FAA) focuses on safety as its primary mission and responsibility regarding commercial service airports. Inspections conducted by the FAA are predominantly centered around safety protocols to ensure that airports comply with federal standards and regulations designed to promote safe operations. These protocols include maintenance of runways, security measures, emergency response plans, and the overall operational safety of the airport. The FAA’s mandate emphasizes the importance of minimizing risks and ensuring a safe environment for passengers, staff, and the general public, making safety protocols a critical factor in their inspections.

The other options, such as marketing strategies and customer service policies, while important to the overall operation of an airport, do not fall under the primary focus of FAA inspections. Operational budgets may also reflect the financial health of an airport, but they are not directly related to safety and compliance, which is the core concern of the FAA.
