Annual obstacle monitoring survey

The Civil Aviation Safety Authority (CASA) Manual of Standards (MOS Part 139 Sect 7.2) and Sydney Airport’s Airport Operations Manual requires an annual instrument survey of approach, take off and transitional surfaces of all of our runways.

This survey is conducted in the final quarter of each year and the ‘Type A’ results are published in the form of listings, after the first quarter of the following year.

The 2023 survey results; listings (xlsx/m) & (pdf) are available to download below:
