Passenger Service System
A passenger service system (PSS) is a series of critical systems used by airlines. The PSS usually comprises an airline reservations system, an airline inventory system and a departure control system (DCS). Modules Generally the PSS is made up of modules that are used to manage different parts of the airline’s business. The airline reservations system is the system that allows an airline to sell their inventory (seats). It contains information on schedules and fares and contains a database of reservations (or passenger name records) and of tickets issued (if applicable). The airline inventory system may or may not be integrated with the reservation system. The system contains all the airline’s flights and the available seats. The main function of the inventory system is to define how many seats are available on a particular flight by opening or closing an individual booking class in accordance with rules defined by the airline. The departure control system (DCS) is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Departure Control System
A departure control system (DCS) automates processing an airline's airport management operation, which includes managing the information required for airport check-in, printing boarding cards, baggage acceptance, boarding, load control and aircraft checks. Today, DCS mostly (98%) manage e-tickets using interfaces from a number of devices, including check-in kiosks, online check-in, mobile boarding cards, and baggage handling. DCS are able to identify, capture and update reservations from an airline's computer reservation system for passengers stored in a so-called passenger name record (PNR). A DCS is used to update reservations, typically as checked-in, boarded, flown or another status. Additionally and increasingly, a DCS for some city-pair sectors may also interface with immigration control (such as Advance Passenger Information System Advance Passenger Information System or APIS is an electronic data interchange system established by the U.S. Customs and Border Prote ...

Passenger Name Record
A passenger name record (PNR) is a record in the database of a computer reservation system (CRS) that contains the itinerary for a passenger or a group of passengers travelling together. The concept of a PNR was first introduced by airlines that needed to exchange reservation information in case passengers required flights of multiple airlines to reach their destination ("interlining"). For this purpose, IATA and ATA have defined standards for interline messaging of PNR and other data through the "ATA/IATA Reservations Interline Message Procedures - Passenger" (AIRIMP). There is no general industry standard for the layout and content of a PNR. In practice, each CRS or hosting system has its own proprietary standards, although common industry needs, including the need to map PNR data easily to AIRIMP messages, has resulted in many general similarities in data content and format between all of the major systems. When a passenger books an itinerary, the travel agent or travel websit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Center Of Gravity Of An Aircraft
The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft. To ensure the aircraft is safe to fly, the center of gravity must fall within specified limits established by the aircraft manufacturer. Terminology ;Ballast: Ballast is removable or permanently installed weight in an aircraft used to bring the center of gravity into the allowable range. ;Center-of-Gravity Limits: Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during flight. The CG limits are indicated in the airplane flight manual. The area between the limits is called the ''CG range'' of the aircraft. ;Weight and Balanc ...

Civil Aviation
Civil aviation is one of two major categories of flying, representing all non-military and non-state aviation, both private and commercial. Most of the countries in the world are members of the International Civil Aviation Organization and work together to establish common Standards and Recommended Practices for civil aviation through that agency. Civil aviation includes three major categories: * Commercial air transport, including scheduled and non-scheduled passenger and cargo flights * Aerial work, in which an aircraft is used for specialized services such as agriculture, photography, surveying, search and rescue, etc. * General aviation (GA), including all other civil flights, private or commercial Although scheduled air transport is the larger operation in terms of passenger numbers, GA is larger in the number of flights (and flight hours, in the U.S.) In the U.S., GA carries 166 million passengers each year, more than any individual airline, though less than all the airl ...
