Regulations for
Aircraft noise
All civil aircraft operating in Australia are required to comply with the Air Navigation (Aircraft Noise) Regulations 2018 regardless of size, purpose or ownership.
As an aircraft operator/owner you have responsibility to ensure your aircraft meets these regulations.
Eligibility to operate the aircraft in compliance with the Air Navigation (Aircraft Noise) Regulations 2018 does not override any conditions on operation of your aircraft which have been specified under any other Acts, Regulations, Orders or Instructions administered by Airservices Australia, the Civil Aviation Safety Authority or other relevant Federal or State authorities (for example, curfew restrictions).
The Regulations specify the following aircraft types/categories as exempt and therefore these aircraft do not require a noise assessment or certificate:
- a state aircraft
- a hot air balloon
- a propeller-driven aircraft that is specifically designed, and used exclusively, for:
-
- aerobatic purposes
- firefighting purposes
- agricultural operations
- environmental operations.
-
Meeting the
Regulations
There are multiple ways that aircraft operators and owners can meet the Regulations. The most appropriate method will depend on the aircraft model, age and how the aircraft is operated. Options include the following:
This is a method of compliance available to aircraft engaging in air navigation within Australia only through Section 12 (Deemed) of the Air Navigation (Aircraft Noise) Regulations 2018 and is the most common method of compliance. Most aircraft owners in Australia meet the Regulations through Section 12, because their aircraft holds existing international noise certification. For aircraft intending to undertake international air navigation, the Deemed path is not appropriate.
For your aircraft to be Deemed, you must carry evidence of existing international noise certification on the aircraft. Our Deemed self-service portal has been developed to help you locate and confirm that you have this evidence. It should take you approximately 15 minutes to complete this process.
If the requirements of Section 14(3)(a) are satisfied, we can issue you with a permit to operate without a noise certificate. This is appropriate for aircraft that do not hold existing international noise certification including older, experimental or amateur-built aircraft.
A permit cannot be used for operations during the curfew period at relevant airports.
To apply for a permit to operate without a noise certificate, please complete the Permission to Operate Without a Noise Certificate form.
You will be asked to provide performance data in your application form, which will be used to determine eligibility for a permit to be issued. You will receive a confirmation email once your application has been submitted successfully. Our standard processing time to issue a permit is 5-10 business days.
We can issue an Australian noise certificate, in accordance with clause 1.5 of ICAO Annex 16, Part II Chapter 1, where an aircraft holds existing international noise certification. While similar to an aircraft being Deemed, you will be issued an Australian Noise Certificate rather than using existing documentation as your evidence of compliance.
If an aircraft is operated internationally, evidence of noise certification under ICAO, Annex 16, Volume I may be required before an aircraft is given permission to operate, by the applicable country. An Australian Noise Certificate is generally accepted as evidence of compliance under ICAO, Annex 16, Volume I and therefore is recommended for aircraft undertaking international air navigation.
While ICAO, Annex 16, Volume I, II-1-1.8 specifies: “Contracting States shall recognize as valid a noise certification granted by another Contracting State provided that the requirements under which such certification was granted are at least equal to the applicable Standards specified in this Annex” this does not guarantee acceptance by other countries. Such decisions are at the discretion of each individual country, based on their specific regulations and evidence requirements.
To apply for an Australian Noise Certificate, please complete the Australian Noise Certificate form. A confirmation email, requesting evidence for submission, will be sent to your email address when your application is submitted. Processing your application cannot commence until the required evidence is received. Our average processing time is 4 weeks, once all evidence has been submitted.
We can undertake noise certification testing of aircraft, to the applicable ICAO, Annex 16, Volume 1 noise standards. Noise certification testing is generally only required where the manufacturer of an aircraft or aircraft modification, developed in Australia, wishes to hold international noise certification. This may be sought if the manufacturer intends to sell their aircraft or modification, particularly internationally.
Noise certification testing requirements, costs and process will depend on the individual aircraft and circumstances. To request noise testing, please email us at noise.assessment@airservicesaustralia.com
If you need noise assessment for aircraft in one of the below categories you will need to apply directly to the Department:
- historical aircraft [Section 14(3)(b)]
- adventure flights/airshows [Section 14(3)(d)]
- non-scheduled flight/public interest [Section 14(3)(c) or 19(1)]
Further information on the application process is available on the Department of Infrastructure, Transport, Regional Development and Communications website.
If we receive an application for an aircraft, which falls under one of the above categories, we will refer your application to the Department and notify you that it has been referred.
Please access our aircraft noise flow chart for details on the process, including required documentation for each of the aircraft noise services available.
If you are uncertain which option is most suitable for your aircraft, please use the Deemed self-service portal which will assist you to identify the most suitable method of compliance.
Changes to
The deemed process
We worked with the Department of Infrastructure, Transport, Regional Development and Communications to speed up and simplify the Deemed process, for aircraft owners. Previously assessment for the Deemed path was undertaken though the standard Aircraft Environmental Assessment form. This process changed in August 2019.
By moving Deemed assessments to the self-service portal, you can confirm that your aircraft meets the requirements on your own. For most aircraft, this will:
- Only require access to the aircraft’s flight manual (AFM) or pilot operating handbook (POH)
- Take approximately 15 minutes, or less, per aircraft.
Because the Regulations only require proof, often through the AFM/POH, for an aircraft to be Deemed - you will only need to carry your AFM/POH in the aircraft.

Frequently asked questions
Compliance with the Air Navigation (Aircraft Noise) Regulations 2018
The Deemed self-service portal can be accessed here.
To apply for an Australian Noise Certificate or a Permit to Operate without a Noise Certificate, please complete the applicable form above.
- For a permit, you will be asked to provide performance data in your application form, which will be used to determine eligibility for a permit to be issued. You will receive a confirmation email once your application has been submitted successfully.
- For a noise certificate, a confirmation email, requesting evidence for submission, will be sent to your email address when your application is submitted. Processing your application cannot commence until the required evidence is received.
Yes, when filling out your application, state that the aircraft registration is ‘to be confirmed’.
Any aircraft that is not exempt under the Air Navigation (Aircraft Noise) Regulations 2018, is required to carry a noise certificate on board the aircraft at all times (under Section 11 of the Regulations) – either in the form of an Australian Noise Certificate or evidence that this aircraft is Deemed, through international noise certification.
Where a permit to operate without a noise certificate has been issued, either by Airservices or the Department, this also is required to be carried on board the aircraft at all times.
This is asking that you demonstrate how you are complying with the Air Navigation (Aircraft Noise) Regulations 2018 and actual evidence will depend upon your method of compliance. If you have applied for an Australian Noise Certificate, that will be the item you provide.
- For an exempt aircraft, you will need to advise that your aircraft is exempt and under which category.
- For an aircraft which is deemed, provide a copy of the evidence you hold on the aircraft of existing international noise certification.This may be from your AFM/POH, a manufacturer or another country’s noise certificate or a TCDS. Access the Deemed self-service portal if you need assistance identifying your evidence.
No. We are only able to conduct assessments for aircraft who are registered in Australia, as per ICAO, Annex 16, Volume I, II-1-1.4.
If you are importing an aircraft from a foreign country, for registration in Australia, please specify Australian registration information in your application.
A noise certification test is required:
- when an aircraft type and configuration requires an Australian Noise Certificate and is yet to be noise-certified or
- when there isn’t sufficient evidence of a noise certificate being issued or recognised by an international authority.
If noise testing is required, charges will apply.
If your aircraft has existing international noise certification, even though you do not intend to fly into a curfewed airport, you are required either confirm the aircraft is Deemed or apply for an Australian Noise Certificate.
- Identification of an aircraft as Deemed is the most common assessment conducted compliance method within Australia.
- The Deemed path is a method of compliance available to aircraft engaging in air navigation within Australia only, through Section 12 (Deemed) of the Air Navigation (Aircraft Noise) Regulations 2018.
- This is not to be confused with being issued a Noise Certificate, see 2. for information on noise certificates.
- Please see the section on the Deemed self-service portal, for more information.
- The issuing of an Australian Noise Certificate under Section 9 of the Air Navigation (Aircraft Noise) Regulations 2018, through validation of existing international noise certification in compliance with the requirements of ICAO, Annex 16, Volume I, is available where satisfactory supporting evidence is supplied to the assessment team. The issuing of an Australian Noise Certificate:
- is done by the Certificating Authority (in Australia this is Airservices)
- requires the submission of satisfactory evidence to enable us to validate that the aircraft holds existing international noise certification that is demonstrated to be at least compliant with the requirements of ICAO, Annex 16, Volume I
- has an average turnaround of four weeks – the actual timeframe will vary depending on the individual aircraft and evidence provided.
An Australian Noise Certificate is generally accepted as evidence of compliance under ICAO, Annex 16, Volume I and therefore is recommended for aircraft undertaking international air navigation.
Note – While ICAO, Annex 16, Volume I, II-1.1.8 specifies “Contracting States shall recognize as valid a noise certification granted by another Contracting State provided that the requirements under which such certification was granted are at least equal to the applicable Standards as specified in this Annex” this does not guarantee acceptance by foreign states. Such decisions are at the discretion of each individual State, based on their specific regulations and evidence requirements.
For aircraft intending to undertake international air navigation, requirements under international regulations may vary and it is the responsibility of the aircraft owner/operator to ensure that the documentation held is acceptable.
We are unable to provide advice on foreign state requirements, or take responsibility for or make guarantees regarding a foreign states acceptance of any assessment or document issued under the Air Navigation (Aircraft Noise) Regulations 2018.
Under the Air Navigation (Aircraft Noise) Regulations 2018, aircraft are exempt due to the way in which they are operated. As we don’t know or control how you operate your aircraft, we can’t issue a certificate for this.
You need to identify whether you are exempt under the Regulation, based on whether your aircraft was designed for and is used exclusively for one of the exempt categories mentioned towards the top of the page.
Eligibility for noise certification can be impacted by different factors, so while it is likely that your aircraft would have noise certification, you need to check you can locate this information and show it, if asked.
Even if your manufacturer completed noise certification for your model of aircraft, individual aircraft may not have certification because:
- The aircraft serial number was excluded from the TCDS – for example where there are civil and military versions of an aircraft, the military version generally is covered by a different TCDS and not eligible for the noise certification identified under the civil TCDS.
- The aircraft was manufactured prior to noise certification being obtained and the noise certification doesn’t include the earlier serial numbers.
- A modification was made to the aircraft, post-manufacture, and ongoing eligibility for noise certification wasn’t confirmed in applicable Supplementary TCDS, Type Certificate or Flight Manuals.
- The aircraft model may not hold international noise certification and while there are a number of that aircraft in Australia - they have all applied for a permit to operate without a noise certificate.
- Certification for your aircraft may depend upon its operation – for example some aircraft that can be used for acrobatics, only hold noise certification when not conducting acrobatics.
The Deemed self-service portal has been developed to help you determine whether any of the above cases apply to your aircraft and is available for use 24/7.
This can sometimes occur for aircraft with electric engines installed. We recommend that you complete the Aircraft Noise Assessment form to ensure we can receive and review the full information about your aircraft, and have your contact details. Please make a note in ‘Additional Comments’ about the situation.
Under the Air Navigation (Aircraft Noise) Regulations 2018, Section 6 (1)(e) specifies that subsonic aircraft may operate if “the aircraft was registered under the Civil Aviation Regulations 1988 on or before 6 December 1990 and continues to be registered under Part 47 of the Civil Aviation Safety Regulations 1998”. This means that as long as your aircraft has been on the Australian registry continuously, since before 6 December 1990, you are compliant with the Air Navigation (Aircraft Noise) Regulations 2018.
For aircraft with are neither a subsonic or supersonic aircraft, Sections 6(3)(e) has a similar clause “the aircraft was registered under the Civil Aviation Regulations 1988 on or before 6 December 1990 and continues to be registered under Part 47 of the Civil Aviation Safety Regulations 1998”.
To be eligible for this method of compliance, the aircraft must have been on the Australian registry continuously from 6 December 1990 onwards. While this compliance method is self-identified, you would need to be able to demonstrate this, if asked.
About the deemed self-service portal
From 1 August 2019, you no longer need to apply to Airservices for an assessment to confirm that your aircraft holds existing international aircraft noise certification. The self-service portal helps you confirm this yourself.
The Regulations only require that proof of international noise certification is held in the aircraft, in order for an aircraft to be ‘Deemed’ to hold an Australian noise certificate. This can be through:
- the aircraft’s AFM or POH, including any updates or supplements; OR
- the Type Certificate Data Sheet (TCDS); OR
- a signed and dated noise certificate from the manufacturer or another nation state.
The self-service portal allows you to use your own documentation to check that your aircraft is eligible, under Section 12 of the Regulations.
You will be required to be able to demonstrate that the documentation for your aircraft confirms existing international noise certification (for the exact aircraft configuration). This can be through the correct page of the AFM/POH, TCDS or your noise certificate, to demonstrate eligibility as ‘Deemed’.
Owners will no longer need to carry any additional documentation when an aircraft is ‘Deemed’ to hold an Australian noise certificate, other than the AFM/POH, TCDS or noise certificate in the aircraft.
Most mass-produced aircraft will be able to demonstrate eligibility for Section 12 using the aircraft’s AFM/POH.
If this can’t be determined using your AFM/POH or other documents, the self-service portal will ask you to apply to Airservices via the Aircraft Noise Assessment form.
No. The self-service portal is there to help you, when you need it.
If you know your aircraft’s AFM/POH has noise certification information and you can find the correct page (if asked) – then you don’t need to use the portal.
We do, however, recommend that you use the self-service portal if it is your first time identifying if your aircraft is ‘Deemed’.
For a noise certificate to be valid it must be:
- signed and dated by the manufacturer or other country/nation-state
- list the details for your exact aircraft, including the correct serial number with the current configuration.
Noise certificates from other countries/nation-states will all have a similar format, with the logo for the issuing body at the top of the document – for Australian noise certificates, this is the Department of Infrastructure, Transport, Regional Development and Communications. An example of an Australian noise certificate is provided below for information.
The Air Navigation (Aircraft Noise) Regulations 2018 require that you hold evidence of international noise certification in your aircraft – generally, this will likely be in your AFM/POH. The Deemed self-service portal is provided to assist you to locate and evaluate the evidence already held about your aircraft, and as long as you can identify the correct information – you don’t need any additional documentation to prove this.
If you are unsure about the evidence you have found for your aircraft, after having used the Deemed self-service portal - you can apply for an Australian Noise Certificate. In order to issue an Australian Noise Certificate, we will review your evidence and verify your aircraft’s eligibility. Please note that this process takes an average of four weeks and requires that you submit evidence for us to review. See the FAQs on ‘Applying for an Australian Noise Certificate’ below, for more information.
The Pilot Operating Handbook for the Robinson R22 helicopters does not include confirmation that the R22 holds international noise certification.
The R22 has been tested and holds international noise certification through ICAO, Annex 16, Volume 1, as confirmed in the EASA TCDS. To be deemed under Section 12, you must hold evidence of existing international noise certification in the helicopter - by carrying the EASA TCDS, you meet the evidence requirement for the aircraft to be deemed under Section 12.
Please ensure that you confirm your exact model, configuration and serial number are listed in the EASA TCDS.
Applying for an Australian noise certificate
If you plan to operate the aircraft internationally, you should apply for an Australian Noise Certificate.
When buying an aircraft overseas, some countries may also require that your aircraft holds an Australian Noise Certificate before you have permission to fly the aircraft back to Australia.
The average Australian Noise Certificate will be returned four weeks after the application and all evidence has been received. Actual timeframes can vary dramatically based on the available evidence and also how many modifications have been made to the aircraft post-manufacture.
If you have a specific target date, such as for a Certificate of Airworthiness or scheduled ferry date for the aircraft, we recommend you let us know when you submit the required evidence. Then we can ensure the noise certificate is completed in time, or let you know if this timeframe won’t be possible.
For an aircraft which holds existing Noise Certification, it is eligible to be issued an Australian Noise Certificate or can be confirmed as Deemed, via the Deemed self-service portal.
Before issuing an Australian Noise Certificate, we will verify that noise certification exists, based on the evidence provided. Each application for an Australian Noise Certificate is assessed independently of any previous assessments conducted. This ensures that there is rigour in the process and accountability both of operators and the assessment team.
You will receive an email upon submission of your application specifying the evidence required. Evidence must demonstrate that the aircraft holds international noise certification, the certified noise levels and that this certification applies to the aircraft serial number and configuration for which the assessment is being undertaken.
The minimum evidence requirements to demonstrate this are:
- A Type Certificate Data Sheet (TCDS) – issued by the European Aviation Safety Agency (EASA), the Federal Aviation Administration (FAA) or other international certification bodies recognised by the International Civil Aviation Organisation (ICAO). To be valid. the TCDS must:
- be the current TCDS
- be in English
- include the specific aircraft model and configuration which is being assessed
- The original Approved Flight Manual (AFM) – this must be the AFM that has been issued to the aircraft serial number for which the application has been submitted. From the AFM, you must supply:
- the cover page of the AFM which demonstrates that the AFM is allocated to the specific aircraft being assessed, through the display of either serial number or registration for the aircraft
- page or pages confirming noise certification from the same AFM, including the certified noise levels.
The evidence of noise certification can be made through a combination of sources, though must include the Type Certificate Data Sheet (TCDS) and Approved Flight Manual (AFM), as described previously. While the above evidence is the minimum accepted, you may find that further information is required in order to demonstrate that the aircraft is eligible for an Australian noise certificate.
The below list is not exhaustive but includes additional sources which may be required:
- your AFM including any supplementary updates – often under a section titled Noise Characteristics. You will need to provide a copy of the first page of your flight manual and the page confirming noise certification
- Federal Aviation Administration Type Certificate Data Sheets (TCDS) Database at: https://drs.faa.gov/search
- European Aviation Safety Agency Type Certificate Datasheet for Noise (TCDSN) at: https://www.easa.europa.eu/document-library/type-certificates
- the aircraft manufacturers website.
Applying for a permit to operate without a noise certificate (under Section 14(3)(a))
If you responded ‘no’ to the question, ‘is the aircraft noise certified?’ then you will need to provide performance specifications for your aircraft. We will use the performance specifications to estimate a noise level and determine whether your aircraft is eligible to be issued a Section 14(3)(a) permit.
If these calculations indicate your aircraft is not eligible for a Section 14(3)(a) permit, it will require a referral to the Department of Infrastructure, Transport, Regional Development and Communications, for permission to operate.
Permission to Operate without a Noise Certificate under Section 14(3)(a) is issued to the aircraft owner, for a specific aircraft serial number and aircraft configuration, rather than being issued to the aircraft.
A new permit needs to be applied for if ownership of the aircraft changes, because if you cease to own or operate the aircraft, the approval issued to you would no longer be valid for that aircraft. This provision is no different to registration on the Australian aircraft register, which must be updated if there is an owner change for a particular aircraft.
Unless your aircraft is exempt or holds existing international noise certification, you will need to demonstrate compliance with the Air Navigation (Aircraft Noise) Regulations 2018 by obtaining a permit.
We can issue a permit for aircraft where the estimated noise levels for the aircraft, do not significantly exceed the relevant ICAO standard applicable for the aircraft. If we anticipate that the noise levels for your aircraft are going to significantly exceed the standard, referral to the Department of Infrastructure, Transport, Regional Development and Communications for a permit, will be required.
The Air Navigation (Aircraft Noise) Regulations 2018 state that an aircraft is permitted to operate for “the undertaking of testing the aircraft is undergoing testing required by the Civil Aviation Safety Authority, or an authorised person appointed under the Civil Aviation Safety Regulations 1998, to determine whether a certificate of airworthiness should be issued, renewed or validated under those Regulations”. As such, you are permitted to undertake testing prior to applying for an applicable permit.
A Section 14(3)(a) permit requires assessment using the aircraft’s actual performance data to determine an aircraft’s eligibility to operate under the permit. As a result, testing should be completed before applying for a Section 14(3)(a) permit, in order to confirm your aircraft’s performance.
If there are issues obtaining permission to commence testing as your aircraft will be operating without evidence of noise certification or a permit, we can provide a 6-month time-limited permit. Please complete the Aircraft Noise Assessment form and provide estimated performance specifications, where applicable. You should also make a note for the assessor that testing has yet to commence.
Once testing has been completed, you will need to reapply for an on-going Section 14(3)(a) permit, including providing your confirmed performance data.
If you intend to only use your aircraft for adventure flights, you will need to apply for an Adventure/Airshow permit from the Department of Infrastructure, Transport, Regional Development and Communications
If you intend to fly your aircraft for Adventure flights but also other purposes, you can apply for a Section 14(3)(a) permit which can include permission to conduct adventure flights. Note that you will need to identify airports that adventure flights will be conducted from and provide evidence of consultation with applicable airports and local councils, at the time of application.
Yes – if you have permission under your Section 14(3)(a) permit to undertake adventure flights, there are different conditions when conducting adventure flights. These conditions are the same as you would be issued under a Section 14(3)(d) permit.
Unlike the standard Section 14(3)(a) permit, evidence of consultation with affected airports and local councils will need to be submitted to the Department every three years. If this evidence is not submitted, permission for conducting adventure flights will expire.
If you’re existing Section 14(3)(a) permit does not identify that adventure flights can be conducted and the airports from which this permission applies, you will need to apply to the Department of Infrastructure, Transport, Regional Development and Communications for a Section 14(3)(d) permit.
If you’re existing Section 14(3)(a) permit provided permission for adventure flights, evidence of consultation with affected airports and local councils will need to be submitted to the Department after the first year. Generally, the Department will then issue permission for a further three years.
Please refer to your permit for additional information.
Unfortunately, no.
Permits under Section 14(3)(a) are only available to propeller aircraft, including rotor aircraft. If you have a jet aircraft, which does not hold existing international noise certification, you should contact the Department of Infrastructure, Transport, Regional Development and Communications to discuss an alternate permit.
Permits issued by Airservices are issued based on our ability to make an estimate of the noise levels that your aircraft will produce, and that they are within an acceptable level. For warbirds, this can be difficult due to the different construction methods, materials and potential operation style.
When there is uncertainty, Airservices and the Department work closely together to identify the best option for individual aircraft in these categories. Generally, we recommend the following:
- If you currently hold a permit for your aircraft and either it has expired, you have recently bought the aircraft or the aircraft has been modified, reapply for a new permit from the same organisation who issued the existing permit.
- If you have a Nanchang CJ6A or Yak 52, please apply to Airservices for a permit to operate without a noise certificate. Airservices has undertaken sample noise testing in collaboration with the Department, of a number of aircraft during 2018. These aircraft models were found eligible for a permit from Airservices under Section 14(3)(a).
- If you intend to operate your aircraft for adventure flights, display or in airshows only, please apply to the Department for an appropriate permit. Aircraft used only for these purposes are not eligible to operate under a Section 14(3)(a) permit.
For any other warbird or historic aircraft, please apply to Airservices for a permit to operate without a noise certificate under Section 14(3)(a). We will review your application and determine whether it is eligible for a permit under Section 14(3)(a) or better suited to receive a permit from the Department. If a permit from the Department is required, we will refer your application to the Department and let you know this has occurred.
A time-limited permit is issued in two circumstances, when either you haven’t completed test flights of an amateur built aircraft or the noise associated with your aircraft is uncertain and a sample noise test is required to confirm likely noise levels.
- If you need to complete test flights, the permit will enable you to conduct these. Once completed, please reapply via the Aircraft Noise Assessment form for a permit to operate without a noise certificate, including the performance specifications determined during your test flights.
- If sample noise testing is required, you will need to contact Airservices to arrange a time for this testing to occur. Costs may apply and will be discussed prior to testing being undertaken.
Permits issued under Section 14(3)(a) do not have an expiry date generally (excluding time-limited permits and permission to conduct adventure flights). A new permit will be required under certain circumstances including if the aircraft owner changes or the aircraft’s configuration changes.
Full details of the permits conditions are provided in the permit, when issued. Please refer to the conditions of your permit for more information.
