What do you know about Airports?

The airport is a multifaceted transportation hub that handles surface vehicles, freight, passengers, and airplanes. It serves as a center for travelers changing from ground to air transportation and vice versa.

The process of running airports is incredibly challenging since it involves a sophisticated network of services for passengers, aircraft support, and aircraft control. Aside from serving as vital hubs for travel and other forms of transportation, airports can also provide significant employment. Airports are also significant local sources of air pollution, noise pollution, and other environmental consequences, making them places where the environmental effects of aviation are felt most keenly. Airports are sensitive infrastructure to natural disasters, extreme weather, and sea level rise brought on by climate change.

International and domestic

Let us first distinguish between the two (2) most popular types of airports. An international airport offers flights from all over the world, whereas domestic airports only offer flights from within the nation. In other words, a domestic US airport would only provide flights from other US cities or states.

Domestic airports will not have international flight options, while international airports will have domestic flight options. They are only able to offer flights to and from within the nation since they lack all of the essential customs and border control infrastructure for entry and exit.

For international flights, you will have to travel through customs and the arrival gate, where you will have to present to the border agent your passport and visa and have the chance to declare whatever you need to.

What is used to identify airports?

IATA codes, also known as IATA location identifiers, are three-letter codes that are typically used to identify airports but can also be used to designate multimodal transportation facilities such as bus terminals, ferry terminals, rail stations, and helipads.

Every official airport in the world has been assigned a three-letter IATA code and a four-letter ICAO code, from the largest, Dammam/King Fahd International Airport (ICAO: OEDF, IATA: DMM) in Saudi Arabia, to the smallest, Saba/Juancho E. Yrausquin Airport (ICAO: TNCS, IATA: SAB), on the Dutch Caribbean island of Saba.

If you notice that the airport codes for LAX (Los Angeles) and PHX (Phoenix) both contain the letter X, what does that mean? Nothing. In the 1940s, when airport codes switched from having two to three letters, it was merely added.

Airport areas and components

It is conventional to divide an airport's various parts into three main categories: landside areas; airside facilities; and the passenger terminal building (PTB), which serves as the interchange between the two (airside and landside).

Landside and airside descriptions of airports can be distinguished. The landside parts describe how passengers enter and exit the airport terminal building as well as how they navigate it to board the aircraft. The movement of aircraft on an airport's ground is referred to as "airside."

A) LANDSIDE AREA

Non-passengers are welcome in the landside area, and the general public, even those who are not traveling, has access to the landside area. It does not qualify as a "secure" area in the same way as the airside area because it has check-in and ticketing desks. Various aviation and non-aviation-related activities, like passenger processing, public access, commercial zones, and airport cities, may be accommodated in the landside area.

Facilities on the Landside Area:

1. Parking Areas: Paid and free parking areas for public or private vehicles.

2. Access Roads and Viaduct: Infrastructure leading to and from the terminal.

3. Services Buildings: This may include generator areas, electrical services, and utility buildings.

4. Support Buildings: Ticketing and airline offices, medical facilities, and other buildings outside of PTB that are in the airport areas.

B) AIRSIDE AREA

The areas of the airport surrounding the aircraft that are exclusively accessible to travelers and employees are referred to as the airside area, and they are strictly regulated. Given that everyone has access to flights and aircraft, it may also be referred to as the "sterile region" because it is assumed that everyone in the vicinity has undergone security screening. In most airports, the duty-free stores and, frequently, the lounges are located on the airside.

Airside is divided into 3 areas:

1. Runways: An airplane uses a runway, which is a paved land strip, to land and take off. There are no obstacles to it, and it is level. The runway has unique markings that set it apart from other roads. Similar to this, after sunset, specifically installed lighting aids in safe aircraft landing.

2. Taxiways: An airport's taxiways connect the runways with the aprons, hangars, terminals, and other facilities for aircraft. Despite the fact that smaller general aviation airports occasionally employ gravel or grass, they typically have a hard surface like asphalt or concrete. High-speed or rapid-exit taxiways are generally built in congested airports to enable airplanes to leave the runway more quickly. This enables the plane to leave the runway more quickly, allowing another to land or take off in less time.

3. Apron: An area called an "apron" is where planes are parked. The loading and unloading of aircraft is another usage for it. Ordinarily paved, the apron is situated in front of the terminal building or close to the hangars. The amount of space needed for the apron and its layout is typically determined by the anticipated number of aircraft at the airport. While designing, aircraft characteristics were also taken into account.

Interesting facts about airport surfaces

The media and other non-aviation sources often refer to the exterior of an airport as "tarmac." In the field of aviation, the word "tarmac" has no significance and is not used in professional contexts. Tarmac is short for Tarmacadam, an unrefined paving substance created more than a century ago that is inappropriate for use on contemporary airport surfaces.

Airport flooring should not be referred to as "Tarmac" in a formal context. It is more appropriate to use terminology like "runway," "taxiway, "apron," "movement area," "no movement area," etc. to describe airport surfaces.

C) PASSENGER TERMINAL BUILDING (PTB)

One of the main components of the airport infrastructure is the Passenger Terminal Building (PTB). It serves as both a city's and its citizens' entry point to the outside world. Airport terminals now serve as more than just a place to arrive and depart. The original transportation link is no longer the only function that terminals now house under one roof. These auxiliary activities include things like working, shopping, and entertainment.

Passengers buy tickets, move their bags, and go through security inside the terminal. Concourses are the structures that enable access to the aircraft (through gates). Nevertheless, depending on how the airport is set up, the terms "terminal" and "concourse" might occasionally be used interchangeably.

Categorically, PTB is the area where the airside and landside are divided. If you are an outbound passenger, the PTB areas before the passport control belong to the Landside section, and all areas of the PTB after the passport control are part of the Airside areas.

Passenger Terminal Buildings (PTB) Areas:

1. Arrival Area: the area of an airport where incoming passengers arrive.

2. Departure Area: the part of an airport that deals with passengers who are leaving.

3. Departure Gate: the area in an airport where passengers wait before getting onto an aircraft.

Interesting Facts for Airport Design

Arrival zones are often on the lower or ground floor of the terminal, whereas departure areas are typically on the higher level. Moving luggage and departing passengers from the second floor to the aircraft would be simpler in the event of departures or departures of people because gravity would support them. The ground staff would have a considerably easier time downloading items from the plane to the airport in the event of arrival, and placing those items in the area designated for baggage claims would be even simpler.

D) Other Notable Areas of the Airports

Passenger Loading Bridge (PLB): A mechanically powered piece of equipment that spans the distance between the terminal and the aircraft for pedestrian foot traffic or other mobile equipment to help passengers safely transition from the airplane to the terminal.

Air Traffic Control (ATC) Tower: Visual surveillance from the air traffic control tower is the main means of managing the immediate airport environment. On the grounds of the airport, there is a tall, windowed building called the Tower. Aircraft and vehicles working on the airport's taxiways and runways, as well as aircraft in the air within a range of 5 to 10 nautical miles (9 to 18 km), depending on the airport's protocols, are separated from one another and moved efficiently by air traffic controllers.

A Hangar: A hangar is a structure where planes are kept when they are not in use. Large, open structures called "hangars" allow for the possible storage and maneuvering of multiple aircraft. Hangars are utilized for more than just storage; they are also where aircraft maintenance and repair are done.

Aircraft Rescue and Fire Fighting (ARFF) Building: The ARFF facility is home to a group of firefighters that assist with emergency response, risk minimization, crew and passenger evacuation, and rescue during aviation accidents and incidents. This structure offers cutting-edge technologies. If a plane is involved in an accident or catches fire, the flames can be extinguished quickly.

Fuel Depot: A fuel farm or depot is an effective way to store and distribute aviation fuel to several users at an airport. Fuel is delivered to aircraft from airport storage tanks by truck or through an underground hydrant system that transports fuel to the airport apron, where hoses extend the remaining distance to the wing of the aircraft.

Conclusion

By 2022, there will be more than 41,700 airports operating worldwide, with the United States having the most (more than 2,000).

Going to the airport can feel like you're entering a new universe of moving walkways, lengthy halls, and gates to faraway places if you don't fly frequently or if you've never flown before. You might need to figure out which line to take and which direction to go because some airports even have their own tiny train or tram system to assist passengers in getting between terminals.
