Note 1.C This is intended to include the barring of sewers, ducts, tunnels, etc., where necessary to prevent access. Note 2.C Special measures may be required to prevent the access of an unauthorized person to runways or taxiways
which overpass public roads. 8.4.3 Suitable means of protection shall be provided to deter the inadvertent or premeditated access of unauthorized
persons into ground installations and facilities essential for the safety of civil aviation located off the aerodrome. Location
8.4.4 The fence or barrier shall be located so as to separate the movement area and other facilities or zones on the aerodrome vital to the safe operation of aircraft from areas open to public access.
8.4.5 When greater security is thought necessary, a cleared area shall be provided on both sides of the fence or barrier to facilitate the work of patrols and to make trespassing more difficult. Consideration shall be given to the provision of
a perimeter road inside the aerodrome fencing for the use of both maintenance personnel and security patrols. 8.5
Security lighting
At an aerodrome where it is deemed desirable for security reasons, a fence or other barrier provided for the protection of international civil aviation and its facilities shall be illuminated at a minimum essential level. Consideration
shall be given to locating lights so that the ground area on both sides of the fence or barrier, particularly at access points, is illuminated.
8.6 Airport design
8.6.1 Architectural and infrastructure-related requirements for the optimum implementation of international civil aviation security measures shall be integrated into the design and construction of new facilities and alterations to existing
facilities at an aerodrome.
Note.C Guidance on all aspects of the planning of aerodromes including security considerations is contained in the Airport Planning Manual, Part 1.
