13. GUIDELINES FOR EQUIPMENT

Equipment used in support of aviation security shall be approved by the appropriate authority in accordance with the guidelines outlined in this section. Walk-through metal detectors used in passenger screening at airports shall fulfil the following requirements: Security equipment shall be capable of detecting small items of different metals, with a higher sensitivity for ferrous metals in all foreseeable conditions; equipment shall be capable of detecting metal objects independently of their orientation and location inside the frame; the sensitivity of the equipment shall be as uniform as possible inside the whole frame and should remain stable and be checked periodically. Operating requirements The functioning of the equipment shall not be affected by its environment. Alarm indication Metal detection shall be indicated automatically, leaving nothing to the operator's discretion (go/no go indicator system): Controls Equipment shall be capable of being adjusted to meet all specified detection requirements, as well as the volume of the audible alarm. Controls for adjustment of detection levels shall be designed to prevent unauthorised access. The settings shall be clearly indicated. Calibration Calibration procedures shall not be made available to unauthorised persons. Hand-held metal detectors used in passenger screening shall fulfil the following requirements: Equipment shall detect small quantities of metal without being in direct contact with the object in all foreseeable conditions. Equipment shall detect both ferrous and non-ferrous metals. The detector coil shall be designed to pinpoint the position of detected metal easily. Equipment shall be fitted with audible and/or visible alarm indicators. Equipment These requirements and guidelines for X-ray security equipment shall be applicable to any X-ray-based screening equipment that provides an image for an operator to interpret. This includes conventional X-rays as well as EDS/EDDS used in indicative mode. Items Similarly, these requirements and guidelines for X-ray security equipment shall be applicable to every item being screened, whatever its type or size. Any item going on board an aircraft, if it has to be screened, has to be screened to the standards contained in this Annex. Security The X-ray equipment shall provide for the necessary detection, measured in terms of resolution, penetration and discrimination, to ensure that prohibited articles are not carried on board aircraft. Tests Performance shall be assessed using appropriate test procedures. Operational requirements The X-ray equipment shall display a complete image of any item fitting into the tunnel. There shall be no corner cut-off. Distortion of the item displayed shall be kept to a minimum. The belt of the machine shall be marked to indicate where bags are to be placed on the belt to obtain optimum images. Contrast sketching: the X-ray equipment shall have the ability to display groups of grey levels (scan a smaller range). The image of any part of the item being screened shall be displayed on the screen for at least 5 seconds. In addition, the operator shall have the ability to stop the belt and, if necessary, reverse the belt when further examination is required. Screen size: the monitor's screen shall be sufficient in size for the operator's comfort (typically 14 inches and above). Screen characteristics: the screen shall be flicker-free and have at least 800 lines (typically 1024 × 1024 pixels, i.e. high-resolution monitors). Where dual monitors are used, one shall be monochrome only. The X-ray equipment shall indicate visually materials it cannot penetrate. The X-ray equipment shall provide organic and inorganic stripping. The systems shall provide automatic threat recognition to facilitate the operator's search. No unauthorised changes, including maintenance or repair, shall be made. There shall be no change in the hardware or the software of the machine without verifying that it does not adversely affect image performance. The composition of the belt material shall not be changed without verifying that this induces no change in image performance. If modem access for maintenance or upgrades is available, access shall be controlled and monitored.
