Ever since the invention of powered human flight, there has been a need to provide places for these flying machines to take off and land. As technology advanced, the need for an aircraft to land in less than optimal daylight conditions led to the integration of lighting on the airfield. This, now, required the ability to turn these lights on when needed and off when not, leading to the creation of the Airfield Lighting Control System.
In the early days, controlling lights on an airfield was accomplished through use of mechanical switches, allowing the operator to change the lights remotely. Eventually, indicator lights were added to provide a basic level of monitoring. As airports grew in size and complexity, these switch panels also increased in size and complexity.
By the early 1990s, airports needed a better solution than mechanical pushbuttons and switches to manage the control of airfield lights. They started incorporating more advanced technologies to handle the task, using either PLC or PC-based control systems. Airports the world over began installing these more advanced methods to control their lights.
These control systems were also capable of providing their operator with a higher level of monitoring. Along with the ability to monitor whether the lights were on or off, airports could now monitor the electrical characteristics of their lighting circuits and even control and monitor individual light fixtures. These systems also gave the operator the ability to automate lighting control through predefined settings, allowing the operator to control all the lights on the airport by only selecting a few key variables.
Presently, the modern ALCMS (Airfield Lighting Control and Monitoring System) is managing more, increasingly complex operations on the airfield. Standards in both the FAA (AC 150/5345-56B) and ICAO (Annex 14, Volume 1, Part 5) have been defined to ensure quality standards are maintained. Integration between multiple systems is more prevalent than ever before. Operational concepts, such as Runway Status Lights and Follow-the-Greens, are examples of how complex system interactions are slowly becoming the norm instead of the exception. This presents a problem similar to issues witnessed before the widespread use of electronic control systems: the physical space requirements to house all the interfaces for these systems is increasing, without increasing the infrastructure space.
While we are presented with challenges, the future is bright. I believe we will continue to see ever increasing interactions between the complex systems that drive airport operations. We will start to see these systems being presented to the operator on a single unified HMI (Human Machine Interface. The SESAR (Single European Sky Air Traffic Management Research) project is currently working on addressing this with the ICWP (Integrated Controller Working Position) concept. This is helping reduce workload for air traffic and apron controllers thus increasing overall flight safety. ICWPs will continue to evolve, linking airfield lighting control and monitoring with other aircraft control operations including gate docking, low visibility guidance, surveillance, flight plan and progress.
