Perth Airport has started the procurement process for the installation of Category III lighting infrastructure, in a bid to achieve enhanced performance and capability during low visibility operations (LVO).
The Category I aerodrome currently allows landing down to 800m and take-off at 550m visibility.
According to the airport, each year nearly a dozen fog events cause disruption to operations, particularly during peak periods.
Perth Airport chief executive officer Brad Geatches said: "We are working closely with Airservices Australia on the Instrument Landing System upgrade for the main runway to support full Category III delivery, and are progressing with procurement and commissioning.
"The upgrade will enable aircraft to land and take-off at a lower visibility, and reduce operating costs to airlines which currently have to carry extra fuel loads in case of diversions."
As part of this project, airlines representing almost 90% of passengers have agreed to support a certain level of upgrade.
Geatches added: "We are particularly pleased to have airline support for this important infrastructure investment."
The full $36m Category III project will also involve providing upgrades to enable electrical infrastructure.
Work on the Category III LVO project, which will be carried out in three phases, is expected to complete in early 2018. The commissioning of instrument landing system, transmissometers, is due for completion by the end of this year.
Transmissometers, which are owned and operated by Airservices Australia, are designed to electronically measure visibility and allow Civil Aviation Safety Authority approved aircraft to make an approach with a visibility of 550m.
Currently, a set of transmissometers has been installed to service the main runway (03/21) at Perth Airport and is being commissioned.
