Access control system is a restrictive practise for entrance to certain places such as buildings, property, or even a particular room in a building. These methods may be carried out for some reasons. Security and confidentiality are the two primary reasons for these practices. Different organisations use different means to restrict the entry of individuals to a certain area. Receptionists, security guards, and bouncers are the standard human restricting methods employed. Locks and keys can also be used for the same purpose.
In the modern world, the restricting practices are done through the advancements in technology. At airports terminals, a defined terminal access control system is put in place to monitor the entry and exit of people in the airport. The mechanism is an electronic access control system that uses computers. An access is granted or denied depending on the credentials presented. Whenever an entry is allowed, the door opens only for a particular time and then automatically locks itself. The entry or exit is recorded in the system as a transaction. An alarm is usually placed on the door to go off if the door is opened by any other means. When credentials are detected by the reader, the information is taken to a control panel that compares the credentials to the access control list. Upon finding the number on the list, the panel grants entry or exist.
Terminal access control systems are designed to meet the frustrations experienced in most airports when managing the general aviation pilots. It is also used in managing the entire access in general. There are different types of terminal access control system depending on their primary purposes.
Barrier access control for airport staff
It was specially designed for itinerant pilots. The technique is commonly used for delivering restrictive control to entry and exit of airport-based staff. With them, the standard magnetic stripe cards are used. Moreover, the on-board audit and entry/exit system is used. Controlled gates in an airport can be easily accessed by visiting pilots with these cards without going through many access protocols.
Airside / landside access control
Airside/ landside control system has the rare ability to securely process and create its access cards to its users. The management involved in both air and land sections of air transport can use these systems. It controls the movement of people either when the aircraft is in the air, or when it has landed. All the features of a conventional access control systems are housed here.
Automated airport access control for pilots
This system can use any magnetic stripe card that is not necessarily issued by the airports management. An approved credential that is authorised is presented. Some information such as the period of stay is entered into the system to register the user. A magnetic stripe card is then registered and used as the access card for the period of stay. The cards can be loyalty cards or credit cards. Once the period of stay elapses, the system automatically denies any access requested by the card. These systems are very useful as the airport managers will not have to be signalled by pilots some moments before they land.
