Airports are busy places, and larger ones can be quite big, confusing, and stressful to navigate. They are sites of operation for heavy machinery and are subject to various regulations and safety measures to reduce hazards. Airports typically consist of a landing area with a runway or helipad and utility buildings such as control towers, hangars, and terminals. They also feature ground crews, security checks, check-in counters, departure halls, and baggage handling services. During the COVID-19 pandemic, airports experienced reduced travel, with photos of empty planes and descriptions of 'ghost towns' circulating in the media. As air travel rebounds, airports are exploring sustainability initiatives, such as alternative energy production and the integration of electric aircraft.

What You'll Learn
Airport layout and facilities
The layout and facilities of an airport are designed to accommodate the flow of passengers, aircraft, and ground operations. The specific design of an airport depends on factors such as passenger volume, aircraft traffic, and the type of passengers it serves. Airports with a high volume of passengers and aircraft movement tend to have more complex layouts and facilities.
A typical airport layout includes a terminal, runway, taxiway, and ramp or apron. The terminal is the building where passengers go through security, check their baggage, and wait to board their flights. It often includes amenities such as restaurants, shops, and waiting areas. Terminal design can vary based on the type of passengers an airport serves, such as business or leisure travellers, and scheduled or charter flights. For example, Heathrow Airport in London has a terminal designed with a high standard of space and decor to attract business travellers, while Palma Airport on the Spanish island of Majorca has a landside area that accommodates large groups of charter tourists arriving and departing by bus.
The runway is the area where aircraft take off and land, usually made of soft grass, asphalt, or concrete. It has white markings and lamps on the sides to guide pilots during take-off and landing. The taxiway is the path that connects the ramp or apron to the runway and provides access to city roads, parking areas, and public transportation. The ramp, also known as the apron, is where aircraft are parked and can be accessed for boarding and disembarking.
Some airports, known as hubbing airports, receive a large number of transferring and transiting passengers. At these hubs, aircraft arrive in waves, and passengers transfer between flights while the planes are on the ground. This "hub-and-spoke" network design allows for more frequent departures but can result in inconvenient interchanges. The oldest layout for passenger terminals is the open apron design, where aircraft park directly adjacent to the terminal, and passengers walk across the apron to board. However, as airports expanded, this design became impractical for handling large passenger volumes.
To manage the complex operations and high traffic of modern aviation, airports have introduced various innovations. For example, Hartsfield Atlanta International Airport implemented the remote pier concept in the 1980s, where passengers are transported to a remote pier by an automatic people mover before embarking or disembarking. Additionally, large transport aircraft and increased cargo shipping have driven the need for extensive ground facilities, advanced navigation systems, firefighting and rescue services, and various support facilities.

Check-in and boarding
Airports are exceptionally busy places, and larger airports can be quite big, confusing, and intimidating. The check-in and boarding process can be daunting, especially for first-time flyers, but being aware of the steps involved can help ease the stress.
Check-in
Checking in is the first step in the airport process. Most airlines allow passengers to check-in online or via a self-service kiosk starting 24 hours before departure. Online check-in usually involves answering a few security questions, selecting or confirming your seat, and choosing how many bags you will be checking in. You can then download, print, or email your boarding pass. If you are checking in at the airport, you will need to go to a staffed counter or check-in counter, where you will go through the same process. It is important to note that check-in usually closes 1-1.5 hours before departure, and you will need to account for time to get through security and reach your gate.
Security and Boarding
After checking in, you will need to pass through security. Here, you will be required to place all hand luggage and personal items through an x-ray machine for inspection. You will also need to pass through a metal detector. A security officer will scan your boarding pass, and if you are cleared, you can proceed to the departure hall.
In the departure hall, you will need to locate the correct terminal and gate listed on your boarding pass. This may involve walking or taking a tram or bus. Once you reach the correct gate, you can board the plane when your row or group is called. Boarding usually begins 45 minutes to an hour before departure.

Security checks
Check-In
The check-in process is the first step in the security screening procedure. Passengers can choose to check-in online or at the airport's designated counters. During check-in, passengers are asked security questions about the items they are carrying. It is important to be aware of the luggage restrictions and prohibited items to avoid any issues during this stage.
Baggage Screening
Once checked in, passengers proceed to the baggage screening area. Here, all hand luggage and personal items must be placed in an X-ray machine for inspection. This process helps detect any dangerous goods or prohibited items in the baggage. Passengers are required to remove metal items from their persons and place them in trays provided by the security staff.
Metal Detector
After the baggage screening, passengers will typically walk through a metal detector. This is done to ensure that individuals are not carrying any metal objects that could pose a security threat. If the metal detector beeps, indicating the presence of metal, a pat-down search by security personnel may be required.
Boarding Pass Check
At the security checkpoint, an officer will ask for your boarding pass. They will scan the pass to verify its authenticity and match it to your identity. This step ensures that only authorised passengers are allowed to proceed further.
Additional Screening
In some cases, additional screening may be required. This could involve a more thorough inspection of personal electronic devices, such as laptops, tablets, or handheld game consoles. Passengers may also be subjected to secondary screening, including pat-downs or additional questioning, if any suspicious items or behaviours are identified.
TSA PreCheck
The Transportation Security Administration (TSA) offers a trusted traveller program called TSA PreCheck. This program allows pre-approved, low-risk travellers to undergo expedited screening at participating airports. Passengers enrolled in TSA PreCheck can expect shorter wait times and a more streamlined security process.
It is important to note that security measures at airports are constantly evolving to address new threats and maintain the highest levels of safety. Passengers are encouraged to arrive early and comply with all security procedures to ensure a smooth and efficient travel experience.

Sustainability and environmental impact
Airports are exploring ways to reduce environmental impacts and improve community relations. They are complex ecosystems with various services, vehicles, and systems that consume energy and resources. To optimise their sustainability, airports should adopt a system-wide approach, minimising waste, improving recycling, and exploring on-site waste-to-energy systems and anaerobic digestion. Airports can also retain and reuse materials from upgrade works, reducing lifetime emissions and maintaining the value of building products.
Airports are major sources of air and noise pollution, and policies encouraging electric vehicles and ground power for aircraft can reduce these impacts and improve local air quality. Additionally, with the rise of electric aircraft, airports must address the substantial energy requirements for charging, potentially through alternative energy production methods such as solar and wind power.
To enhance sustainability, airports can implement measures to reduce light pollution, monitor indoor air quality, limit toxic substance use, and adopt biophilic design. They should also address the risk of creating heat islands, which can negatively impact the surrounding environment and local wildlife. By tackling these challenges, airports can improve their sustainability and reduce their environmental footprint.
