Airports are large, busy hubs for tourism and transit, with a complex system of aircraft and passenger services. They are usually exceptionally busy, and the larger airports can be quite confusing to navigate. The airport experience has changed in recent years, especially with the introduction of COVID-19 safety measures, but the fundamental structure remains the same. So, what does an airport look like? Airports consist of a landing area with runways and helipads, as well as utility buildings such as control towers, hangars, and terminals. They employ a large number of ground staff to manage aircraft, cargo, passengers, and baggage. Security measures are strict, with hand luggage x-rayed and passengers passing through metal detectors. Airports also provide passenger facilities, such as lounges, restaurants, and shops.
What You'll Learn
Airport design and layout
Landing Area and Utility Buildings
The landing area of an airport includes an open space accessible by air, typically consisting of at least one active surface such as a runway or helipad. Adjacent to the landing area are utility buildings such as control towers, hangars, and terminals. Control towers are essential for air traffic control, providing a bird's-eye view of the airport premises and assisting in aircraft navigation and safety. Hangars are enclosed spaces used for aircraft maintenance, storage, and protection from weather conditions.
Terminal Layout and Design
The design of passenger terminals can vary, with the "hub-and-spoke" model being prevalent in larger airports. This model involves aircraft arriving in waves, allowing passengers to transfer efficiently between flights during connection periods. The oldest terminal layout is the open apron design, where aircraft park directly next to the terminal, and passengers walk across the apron to board. However, this design becomes impractical as passenger numbers increase.
Passenger Facilities and Services
Airports provide an array of passenger facilities and services to cater to different traveller needs. These include check-in counters, baggage drop-off and claim areas, security screening checkpoints, departure halls, and arrival areas. Additionally, larger airports may offer restaurants, lounges, duty-free shops, and other amenities to enhance the passenger experience.
Ground Support and Aircraft Services
Ground crew play a crucial role in aircraft processing, handling tasks such as cargo and baggage management, ramp services, aircraft fuelling, and in-flight service preparation. Efficient ground support ensures quick turnaround times for aircraft, enabling them to maintain their schedules.
Environmental Considerations
Airports are increasingly focusing on sustainability and exploring ways to accommodate electric aircraft. They are investigating alternative energy sources, such as solar and wind power, and considering how airport areas can be used for biomass production. Additionally, energy storage solutions are being examined to balance energy demands during the day and night.
In summary, airport design and layout encompass a complex interplay of functional, safety, and environmental considerations, all aimed at facilitating seamless travel experiences for passengers and efficient operations for airlines.

Airport operations
The operations of an airport begin with passengers checking in for their flights. This can be done online or at the airport's check-in counters or self-service kiosks. Checking in online offers several advantages, such as better seat selection and a reduced likelihood of being bumped in case of overbooked flights. However, checking in at the airport allows passengers to inquire about specific services or request assistance. After checking in, passengers proceed to hand over any luggage that needs to go into the aircraft hold. This luggage is then tagged and processed through security screening to ensure it complies with safety regulations.
Once the luggage is sorted, passengers pass through airport security gates, where their hand luggage is screened through X-ray machines, and they walk through metal detectors. Security officers also scan passengers' boarding passes and may perform pat-downs if the metal detector beeps. After clearing security, passengers proceed to the departures hall, where they wait to board their flights.
Behind the scenes, airport ground crews work diligently to process flights, cargo, passengers, and baggage. This includes navigating baggage carts to and from aircraft, fuelling aircraft, and conducting various inspections to ensure aircraft safety and readiness for the next flight. The efficient work of ground crews enables aircraft to have fast turnaround times between different flights.
Additionally, airports play a significant role in promoting sustainability. They are exploring the integration of electric aircraft, which requires substantial energy and charging infrastructure. To address these challenges, airports are investigating alternative energy sources, such as solar and wind power, as well as biomass production within airport areas. Furthermore, airports are significant employers and hubs for tourism and transit, contributing to the local economy and infrastructure.

Environmental impact
Airports are complex systems that encompass aircraft support services, passenger services, and aircraft control services. They are typically sprawling spaces with a landing area, including a runway or helipad, and utility buildings such as control towers, hangars, and terminals. Airports are major employers and hubs for tourism and transit. However, their operations and expansion have significant environmental implications, which are crucial considerations for various stakeholders, including local communities and agencies.
Airports are sources of air pollution, noise pollution, and other environmental issues, making them acutely susceptible to the environmental effects of aviation. The impact of airport operations on air and water quality is a complex issue that has gained prominence due to the anticipated growth in air travel. Airports are exploring alternative energy production methods, such as solar and wind power, and the potential of airport areas for biomass production. Additionally, they are investigating energy storage solutions to manage the substantial energy demands of electric aircraft, which have shorter ranges and quick turnaround times.
To mitigate environmental impacts, airports may implement projects to reduce noise, improve water quality, and decrease air emissions. For example, soundproofing nearby homes or purchasing noise barriers can help address noise pollution. Airports also need to control the discharge of de-icing chemicals to minimise water quality impacts. Furthermore, they can invest in alternative fuel vehicles and equipment, as well as research new aircraft technology, to reduce noise and air emissions.
The environmental regulatory requirements, as outlined in the National Environmental Policy Act of 1969 (NEPA), and the funding provided through initiatives like the Federal Aviation Administration's (FAA) "Environmental Stewardship" goals, are essential tools to support airports in reducing their environmental footprint. These initiatives are crucial as concerns about environmental impacts have already led to the delay and cancellation of airport expansion projects.

Airport sites and locations
Airports are typically large, busy, and complex places. They are often confusing, especially the larger airports, and security measures can be intimidating. Airports are usually located outside of the city centre, and getting to the airport can take a significant amount of time.
An airport is an aerodrome with extended facilities, mostly for commercial air transport. They consist of a landing area with at least one runway or helipad, and often include adjacent utility buildings such as control towers, hangars, and terminals. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, and emergency services. Airports also have passenger facilities such as restaurants and lounges. Airports require a large amount of land, and they are a major source of noise and air pollution, as well as other environmental impacts. Airports are vulnerable to extreme weather and the effects of climate change, such as rising sea levels.
The airport's ground crew processes flights, cargo, passengers, and baggage. When a flight arrives, ramp services bring a baggage cart to the aircraft, and baggage handlers sort and transport the luggage. Once the passengers and cargo are unloaded, a cleaning crew prepares the aircraft for its next flight by loading supplies and preparing in-flight services. The ground crew will also refuel the aircraft and conduct visual inspections.
The process of checking in and departing from an airport can be stressful and time-consuming. It is recommended that passengers arrive at the airport at least one hour before the recommended minimum check-in time, which can vary depending on the type of flight and luggage. Online check-in is available for some flights, and self-service kiosks are available in the departure halls of larger airports. At the security checkpoint, passengers must pass their hand luggage through an x-ray machine and walk through a metal detector. It is important to remove all metal items and place them in the trays provided. Passengers may also be required to show that any electronic devices are functional.

Airport history
The history of airports can be traced back to the early days of aviation, when the first airfields were established. These early airfields were often little more than open fields or grassy strips of land that were used for aircraft take-off and landing. Some of the prewar airfields, like those in New York City (La Guardia), London (Croydon), Paris (Le Bourget), and Berlin (Tempelhof), were located near city centres. These early airports had unpaved runways or, at most, lightly paved runways with small terminal buildings, rudimentary control towers, and basic landing aids.
During the late 1930s, with the introduction of heavier monoplanes for transport, such as the Douglas DC-3, longer and more extensive takeoff and landing distances became necessary. Airports began to require more complex and larger areas, with paved runways and maintenance facilities. The total area involved in airports rarely exceeded 500 acres (200 hectares) before this time.
Airports played a significant role during World War II, with many countries establishing or expanding their airfields for military purposes. After the war, commercial air transport gained popularity, and airports evolved into major hubs for tourism and transit. They became more complex, with the addition of facilities like control towers, hangars, and terminals to maintain and monitor aircraft.
Over time, airports have continued to grow in size and complexity, with larger airports featuring airport aprons, taxiway bridges, air traffic control centres, and various passenger amenities. They have also become major employers and significant contributors to local economies. However, the construction of new airports or the expansion of existing ones is often met with resistance from local residents due to environmental concerns, impacts on historical sites, and other factors.
As aviation technology advances, airports are also adapting to accommodate new aircraft, such as electric planes, and addressing sustainability challenges. They are exploring alternative energy sources like solar and wind power, as well as investigating the use of energy storage systems to meet the high energy demands of electric aircraft.
