Which of the following is typically found in the main section of an airport building?

The main section of an airport building is designed to facilitate passenger processing and movement. Within this area, you will find the ticket counters where passengers check in for their flights, receive boarding passes, and drop off luggage. Additionally, this section includes boarding gates where passengers await their flights and board the aircraft. This layout is critical for the efficiency and convenience of air travel, allowing passengers to navigate through check-in, security, and boarding all in one centralized location.

In contrast, the control tower is typically located separately from the main passenger areas, predominantly at a height to oversee air traffic. Runways are external structures necessary for aircraft to take off and land, situated outside the airport building itself. The maintenance area is also separated from passenger operations, designated for the servicing of aircraft and not directly accessible to the public. These functions and locations help clarify why the ticket counter and gates are fundamental to the main building's purpose and operations.
