We have developed this plain English guide to help you understand the Part 139 regulations that set out the requirements and standards for aerodromes with published instrument flight procedures. These requirements include standards for aerodrome facilities, obstacle control, operational procedures and safety management.
The guide sets out the regulatory requirements in a concise, clear, easy-to-read, and practical format for:
- Part 139 of the Civil Aviation Safety Regulations (CASR)
- Part 139 MOS.
It contains exemptions, relevant guidance material and advisory documents.
Who the guide is for
This guide is particularly relevant to:
- local councils
- resource and mining companies
- private aerodrome operators
- other organisations responsible for operating certified aerodromes.
It focuses on certified aerodromes supporting domestic and regional air transport, general aviation and non-scheduled international operations.
Feedback
We encourage feedback, including whether the guide provides:
- regulatory information in simple, easy-to-read, and clear language
- a logical structure and format to the information.
