Guidelines for heliports - design and operation - Draft Advisory Circular (AC) 139.R-01 v1.0

Closes 1 Jun 2022

Opened 4 May 2022


This advisory circular (AC) will provide guidance and information on physical and operational standards for heliports. Heliports are not regulated, so the intent of this AC is to provide some foundational specifications to help Helicopter Landing Site (HLS) owners and operators design, construct, maintain and operate their facilities in line with international standards and recommended practices.

Draft AC 139.R-01 v1.0 replaces Civil Aviation Advisory Publications (CAAP) 92-2(2) and 92-4(0) with respect to guidance for HLS owners and operators. Guidance to helicopter pilots on operating to and from HLSs has been published in AC 91-29 v1.0 - Guidelines for helicopters - suitable places to take off and land.

In this draft AC, heliport owners and operators are provided with guidance on:

  • heliport site selection
  • physical characteristics
  • obstacle control
  • visual aids
  • emergency response facilities
  • aeronautical data.

This AC will be of interest to:

  • persons involved in the design, construction, and operation of heliports
  • proponents of heliports
  • helicopter owners/operators
  • planning authorities
  • aerodrome operators
  • the Civil Aviation Safety Authority (CASA).

Why your views matter

CASA recognises the valuable contribution that community and industry consultation makes to the regulatory development process.

This draft AC represents a significant step towards alignment of Australia’s heliport specifications with the International Civil Aviation Organization’s (ICAO) heliport standards and recommended practices (contained in Annex 14 Volume II).

While Annex 14 alignment was a stated goal of the Part 139 post-implementation review project, consultation on specific provisions is essential to ensuring that this guidance material is adequate, suitable and fit for purpose.

Community and industry members are invited to review the document and consider the impact, positive and negative, on existing and future operations at Australian heliports and HLS, including onshore and offshore facilities. Feedback should be provided through the online survey below.

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 and outlines our plans for the AC.
