Computers are an integral part of airport operations and are used in almost every aspect of airport management. From designing airports to ensuring flight safety and providing efficient passenger services, computers have revolutionized the aviation industry. They are used for flight planning, air traffic control, baggage handling, flight information displays, and even entertainment for transit passengers. Computers have improved productivity, enhanced security, and made it possible to quickly modify travel arrangements. They are also crucial for aircraft engineering, scanning, fleet management, and record-keeping.

Computers are used for ticket reservations and e-ticketing services

Airline reservation systems (ARS) are used to sell an airline's inventory (seats). They contain information on schedules, fares, and passenger name records (PNRs). These systems evolved into computer reservation systems (CRS), which are used for reservations and interfacing with a global distribution system (GDS) that supports travel agencies and other distribution channels.

Airlines use CRSs to maintain air travel information, manage bookings, and keep track of booking records in real-time. CRSs are also used to sell inventory through various sales channels, including B2B and B2C. They allow users to book travel services online by interfacing with GDSs and APIs/XMLs. Additionally, CRSs record flight-related information, manage invoicing and accounting, and handle customer and quota management.

GDSs are used to book airline tickets, hotel rooms, rental cars, and other activities. They also provide access to railway and bus reservations in some markets. Modern GDSs, such as Worldspan, Sabre, and Travelport+, have revolutionized the industry by providing instantaneous access to flight information and bookings.

Passengers can book tickets directly on an airline's website, which is integrated with the airline's reservation system. This integration allows airlines to receive commission-free bookings and accept different currencies and payment methods, enhancing the user experience. If passengers choose to buy tickets from a third-party agent, GDSs and meta-search engines mediate between travel agents and service providers.

E-ticketing is an essential aspect of modern travel, removing the need for paper documents and physical queues at the airport. Platforms like Amadeus for Airlines process e-tickets through GDSs, providing a smooth travel experience for passengers.

Flight planning is a critical aspect of aviation operations, and computers play a vital role in this process. Flight officers rely on computers to create and execute flight plans efficiently. With the help of computers, a complex flight plan can be completed in half an hour, a task that would otherwise take up to 4-5 hours if done manually. Computerized flight planning offers significant advantages in terms of cost and time efficiency, providing the most fuel-efficient and RAD-compliant route. Additionally, computers are used by pilots to calculate fuel burn, wind correction, time en route, ground speed, and estimated time of arrival, both on the ground and during flight.

Air traffic control (ATC) is another crucial area where computers are extensively utilized. ATC uses computers to provide precise directions and manage all aspects of air traffic, including aircraft landing, takeoff, and ground traffic operations. The implementation of advanced computer systems, such as the NextGen project in the United States, aims to revolutionize air traffic control. This new computer system will enable any controller, anywhere in the country, to track and manage any plane in US airspace, enhancing the flexibility and responsiveness of air traffic management.

The aviation industry's reliance on computers extends beyond flight planning and air traffic control. Computers are used for aircraft engineering, scanning aircraft before and after flights, fleet management, record-keeping, and human resources. Additionally, computers have revolutionized ticketing and boarding processes, improving efficiency and customer experience. The use of e-ticketing and computerized boarding systems has streamlined airport operations, reducing the time and complexity involved in managing a large number of flights and passengers.

The integration of computers into aviation has been a gradual process, with the first significant step occurring when Boeing designed the Boeing 777 entirely on computers, without using traditional paper designs. This aircraft, known as "the first 21st Century Jet," marked a shift towards computerized design and engineering in the aviation industry. Today, computers are an indispensable part of aviation, and their continued advancement is expected to bring further innovations, such as Airbus's vision of a pilotless cockpit operated by artificial intelligence.
