Commissioning of aerodrome lighting systems – Draft AC 139.C-11 v1.0

Closed 23 Nov 2021

Opened 9 Nov 2021


Aerodrome lighting provides visual guidance for pilots when approaching, landing and operating at an aerodrome at night or in reduced visibility conditions.

Before commissioning any aerodrome lighting system, an aerodrome operator must ensure they complete a series of checks to meet the requirements contained in the Part 139 (Aerodromes) Manual of Standards (MOS).

A new aerodrome lighting system must not be made available for use until it has been commissioned. The replacement or upgrade to an existing commissioned lighting system must also be commissioned before being made available for use.

In certain circumstances, CASA may direct the completion of a ground and/or flight check of an already commissioned aerodrome lighting system. These circumstances include a substantial change to the system or through an adverse performance report from a pilot or aircraft operator.

The aerodrome operator is responsible for providing written evidence to CASA of the commissioning process and for ensuring that all required check reports are obtained prior to requesting a Notice to Airmen (NOTAM) or updating the AIP.


This purpose of Advisory Circular (AC) 139.C-11 v1.0 is to provide general information and advice on the requirements and method of commissioning various aerodrome lighting systems. For those systems that require a flight check as part of the commissioning process, advice on how to  conduct the flight check is also provided.


This AC will be of interest to:

  • aerodrome owners/operators
  • persons conducting ground checks of aerodrome lighting systems
  • persons conducting flight checks of aerodrome lighting systems.

Draft AC 139.C-11 v1.0 will replace AC 139-04(0) - Commissioning of aerodrome lighting systems.

Why your views matter

CASA recognises the valuable contribution that community and industry consultation makes to the regulatory development process. For this reason, we are seeking feedback on whether the draft AC is fit for purpose and provides adequate guidance on:

  • requirements and method of commissioning various aerodrome lighting systems
  • the conduct of the flight check when required as part of the commissioning process.

A copy of the draft AC 139.C-11 v1.0, is provided below as well as appearing on the Feedback page of the survey.

Please read the AC document before providing your feedback.

Note: The MS Word document is not to be used as an emailed submission, unless there are extenuating circumstances and this form of submission has been agreed to by the consultation project lead.

What happens next

At the end of the response period for public comment, we will review each comment and submission received. We will make all submissions publicly available on our website, unless you request your submission remain confidential. We will also publish a Summary of Consultation which summarises the feedback received, outlines any intended changes and details our plans for the AC.
