Chapter 16, Annex I AERODROME SECURITY DEFINITIONS

Restricted Area. A portion of an aerodrome where access is only granted to authorized persons.

Restricted Area Access Point. A location in a security barrier at which a control system is in place that controls access to a restricted area from a non-restricted area.

Screening. The checking, identification, observation, inspection or authorized search of persons, goods and other things in the possession or control of persons.

Security Barrier. A physical structure or natural feature used to prevent or deter access by unauthorized persons to a restricted area.

Sterile Area. A restricted area, including any passenger loading bridges attached to it. It is used to separate passengers who have been screened, or are exempt from screening, and other authorized persons from unauthorized persons at the aerodrome.

RESTRICTED AREAS

All aircraft movement areas (runways, taxiways and aprons) are restricted areas and only those who are authorized have access to these areas. Restricted areas also exist inside the terminal building. The area used by passengers between the time they are screened and the time they board the aircraft is a restricted area (specifically a sterile area). Other areas inside the terminal building that will be a restricted area include:

FENCES

The fences most commonly used as security measures at an aerodrome are chain-link fences erected around the perimeter of the aircraft movement areas. Access through the fence is provided by gates for vehicles and people or through buildings adjacent to the movement areas.

GATES

The gates found in aerodrome fencing can be categorized in several ways: routine, emergency, or occasional access points and vehicle or personnel access points. Additionally, they can be operated manually or mechanically. Gates designed to be operated mechanically should also be able to be opened manually in case of electrical failure. In all cases, a gate that remains open can become a major security problem.
