1 Airfield Lighting Control System ALCS Style 2 ALCS Style 3 Reference to Standards ICAO: Annex 14, Volume I, current edition Aerodrome Design Manual, Part 5 FAA: AC 150/ (current edition) L-890 Airfield Lighting Control and Monitoring System (ALCMS) Advisory Circular (AC) Military: UFC STANAG 3316 IEC: Fig. 1: ATC (Tower) and (Substation) workstation ADB s Airfield Lighting Control System (ALCS) family ranges from Style 1 to Style 7, enabling selection and specific adaptation of Airfield Ground Lighting (AGL) control features for all sizes and levels of complexity of airfield ground lighting systems. Application of ALCS Style 2 and 3 Airfield Lighting Control Systems from ADB enable the air traffic controller to operate the entire lighting system via easy-to-use touch screen monitors. Operational features, system status and fault messages are clearly visualized in well structured masks on the controller HMI in the tower and maintenance HMI in the substation. While the controller work station is focused on the operational status of airfield ground lights, the maintenance station monitors the actual status and error messages of the electrical components, constant current regulators and system interfaces. ALCS Style 2 and 3 are state of the art systems for easy and straight forward control and monitoring of visual aids, tailored to the needs of airports with one or two runways and maximum 32 (Style 2) or 56 (Style 3) airfield lighting circuits (typical: approach, threshold until end of runway, PAPI, taxiways and stopbars). ALCS Style 2 is used for airports with one (1) airfield lighting substation, while Style 3 is used for airports with two (2) substations to power the visual aids. ALCS Style 2 and 3 feature a serial RS 485 Jbus communication interface (2A, 3A) or a multiwire cable connection (2B, 3B) to constant current regulators (CCR) and serve up to 10 digital I/O s per substation. Both versions of the system have a modular design in hardware and software, allowing extensions by adding additional user interfaces in AGL substations. This facilitates modifications for future airport growth and upgrades. A e

2 Functionalities Selection of airfield ground lighting status and intensity per group of lights on runway, taxiways and apron according to the visual range and landing direction - Activation of general lighting settings using an ICAO compliant preset table as per visibility mode (day, twilight, night), runway visual range and category of operations (CAT) - Selection and switching of groups of lights via push buttons on a touch screen - Dedicated taxiway and stopbar control commands Fig. 2: System architecture (example: Style 3, DSL modem with copper cable from Tower to - and Substation and J-Bus to CCRs) Visualization of actual operational, maintenance and alarm status of the ALCS system and the airfield ground lighting equipment - Display of status of group of lights via push button image: on / off / maintenance / error - operation and status visualization with individual Constant Current Regulator (CCR) control and (optional) true feedback indication of lamp status - Detailed list of actual alarms for troubleshooting with sorting, filtering, printing mode, selectable Air Traffic Control (ATC) or maintenance level via user access code ALCS Style 2 and 3 can modularly grow with airport complexity to higher levels (Style 4-7) System Overview and Options ALCS Style 2 and 3 are based on a system design, which is built around a proven and reliable Programmable Logic Controller (PLC) concept providing a powerful range of control functionalities for both ATC operators and maintenance users.

6 Recommendation for Specification The Airfield Ground Lighting Control and Monitoring System has to be designed to ensure a safe and user friendly method of ATC operator interface for airfield lighting in accordance with ICAO Annex-14, Volume-1, including its latest amendments and the ICAO related manuals and Aerodrome Design Manual Part-5. The ALCS shall feature one control workstation in the ATC control tower with one large size touch screen HMI, linked to up to two substations for up to 16 constant current regulators having a serial J-Bus or a multiwire control interface, and 10 I/O under 48 V DC for auxiliaries. Maximum number of controlled circuits shall be 32 or 56, depending on airfield lighting layout, by using circuit selectors. The system shall be based on standard PLC of well known brand for control and monitoring facilities and a COTS SCADA package for the user interfaces of the ATC and maintenance computers. An optional workstation can be added in the ATC control tower and one in each maintenance station with touch screen HMI and printer. Alternatively, an optional maintenance laptop computer can be used in the substations for maintenance activities. In order to safeguard long term availability and reliability of the system, the components in the substation cabinet shall be of industrial grade. The communication medium shall be either telephone cable with DSL modems allowing a distance up to 3 km or fiber optic rings and Optical Media Converter allowing distances up to 15km. Both of them shall use the international Ethernet standard for TCP/IP communication at 10/100 Mbit/s. All the control equipment installed in the substation shall be mounted in an industrial grade cabinet. The cabinet s dimensions and internal layout of equipment shall provide an optimum match for the airport s requirements, also taking into account future upgrade possibilities. Control and monitoring equipment shall be secured with UPS. The status of each UPS is to be monitored on the system s HMIs. Alarms and warnings are issued to the operators when the system is running on UPS or when the batteries get empty. The standard backup duration of the UPS shall be 20 min and can be extended with additional battery packs.
