The scope of work centred on the installation, testing and commissioning of a new Red White Visual Approach Slope Indicator (VASI) system on the existing runway. The VASI system provides pilots with clear visual guidance during landing approach, using a combination of red and white lights to indicate whether an aircraft is on, above or below the correct descent angle. Integrating the system into an operational runway required careful planning and precise execution to ensure both accuracy and minimal disruption to airport operations.
McKay’s works included the laying of underground power, control and airfield lighting cables, along with the surveying, siting and construction of dedicated VASI pads. Following this, the VASI units were erected, aligned, tested and commissioned to meet the required aviation standards. In parallel, McKay installed, tested and commissioned the associated airfield lighting control panel and 400-volt switchgear required to support the new system.
Alterations were also carried out to the existing remote control panels to enable full integration and operation of the new VASI system within the airport’s lighting and control infrastructure. This ensured seamless control and monitoring of the airfield lighting systems from established operational points.
The Queenstown Airport project further established McKay’s capability in delivering specialist airfield electrical systems under demanding conditions. Successfully integrating a new VASI system into an active airport environment reinforced the company’s growing reputation in aviation infrastructure and marked an important step in the development of a portfolio of airport projects that would extend across New Zealand and, in later years, into the Pacific region.
