Frequently asked questions

General questions about the aircraft environmental regulations and your obligations

Does Airservices need to assess my aircraft noise certification or provide me with a noise certificate?

Airservices does not need to issue a noise certificate or assess the aircraft’s noise certification status if your aircraft is noise-certified and you have evidence of its certification, such as in the approved flight manual.

From 1 August 2019, Airservices will release a Deemed self-service portal to help you confirm that your aircraft holds existing noise certification. Until the self-service is released, if you are unsure, please apply for a Deemed assessment and the team will assist you by confirming this, based on your submitted evidence.

I hear that Airservices will be changing the Deemed assessments process in August 2019?

Airservices will be launching the new Deemed self-service portal on Thursday 1 August 2019. The self-service portal will enable individual aircraft owners/operators to determine whether their aircraft holds existing international noise certification, generally within 15 minutes, without needing to apply to Airservices for an assessment, or submitting evidence.

Additional information is available from the Aircraft noise regulations and assessment process page

I am unsure if my aircraft is noise-certified, what do I do?

You should check your Approved Flight Manual and international databases such as the European Aviation Safety Agency Type Certificate Datasheet for Noise (TCDSN) or the Federal Aviation Administration Type Certificate Data Sheets (TCDS) Database to see if your aircraft’s configuration is noise-certified.

If you cannot find the information, please email and they will endeavour to assist you. If your aircraft is not certified, you will be required to apply for permission to operate without a noise certificate under Section 14(3)(a) or apply to have your aircraft noise-certified (charges apply for noise certification).

What modifications may affect the noise characteristics of the aircraft?

Any change to the aircraft has the ability to affect the noise characteristics, examples of these include but are not limited to:

  • engine power increase
  • propeller change
  • weight increase
  • exhaust muffler change
  • aerodynamic change
  • other changes affecting flight performance.

I wish to apply for an aircraft noise assessment however I’m yet to receive my aircraft registration. Can I still apply?

Yes, when filling out your application, state that the aircraft registration is ‘to be confirmed’.

What are the compliance responsibilities for Air Navigation (Aircraft Noise) Regulations 2018?

Any aircraft that is not exempt under the Air Navigation (Aircraft Noise) Regulations 2018, is required by Section 11 to carry a noise certificate on board the aircraft at all times – either in the form of a valid Deemed assessment, Australian Noise Certificate or other evidence of international noise certification.

Where a permit to operate without a noise certificate has been issued, this also is required to be carried on board the aircraft at all times.

Can I apply for an aircraft noise assessment of an aircraft registered in a country other than Australia?

No. Airservices 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.

When is a noise certification test required?

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.

Why do I need to provide evidence of existing Noise Certification?

For an aircraft which holds existing Noise Certification, it can either be Deemed or issued an Australian Noise Certificate. The Aircraft Noise Assessment team will verify that noise certification exists, based on the evidence provided.

Each application is now 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.

When do I provide evidence and how do I know what to provide?

You will receive an email upon submission of your application specifying the evidence required. For a Deemed Assessment, 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.

Where can I locate the required evidence of noise certification?

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 ‘deemed’ to have a noise certificate.

The below list is not exhaustive but includes the most common sources:

I don’t want to fly at a curfewed airport. Can I apply for a 14(3)(a) instead of a Deemed Assessment?

If your aircraft has existing international noise certification, even though you do not intend to fly into a curfewed airport, you are required to apply for a Deemed Assessment and submit appropriate evidence to support your application.

What is the difference between a Deemed assessment and an Australian Noise Certificate?

  1. The Deemed Assessment 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 be aware that this document confirms your compliance based on the evidence provided. While all due care is taken by the assessment team, the owner/operator is responsible under the regulations to ensure that the information and evidence provided is correct. Liability for supplying of incorrect information including aircraft weight, configuration or not supplying the correct flight manual pages, sits with the aircraft owner/operator.

2. 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
  • requires the submission of satisfactory evidence to enable the assessor 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,
  • will be issued in a minimum of 10 business days – the actual timeframe will vary depending on the individual aircraft and evidence provided,
  • may have associated costs. Costs will need to be agreed and paid, prior to the application being processed and an Australian Noise Certificate issued.

My aircraft will be conducting international air navigation – what do I need?

An Australian Noise Certificate is generally accepted as evidence of compliance under ICAO, Annex 16, Volume I and therefore may be more appropriate 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 decision 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 owner/operator to ensure that the documentation held is acceptable.

Airservices Australia 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.

Why am I asked to provide aircraft performance specifications?

If you responded ‘no’ to the question, ‘is the aircraft noise certified?’ then you will need to provide performance specifications for your aircraft. These will be used by the Aircraft Noise Assessment team 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, Cities and Regional Development for permission to operate.

Deemed self-service portal

How will ‘Deemed’ assessments change?

From 1 August 2019, you will no longer need to apply to Airservices for an assessment to confirm that an aircraft holds existing international aircraft noise certification. The self-service portal will help 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 will allow you to use your own documentation to check that your aircraft is eligible under Section 12 of the Regulations.

Where do I access the Deemed self-service portal?

The Deemed self-service portal can be accessed from the Aircraft noise regulations and assessment process page.

How do I show eligibility under Section 12 (‘Deemed’)?

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’.

Furthermore, 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.

What happens if I can’t confirm eligibility?

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.

How do I apply for other Aircraft Environmental Assessment services?

The process for applying for an Australian Noise Certificate or a Permit to Operate without a Noise Certificate will not change. You will still need to complete the Aircraft Noise Assessment form via the Airservices website, and submit any requested evidence, as usual.

I know that my aircraft has international noise certification. Do I need to use the ‘Deemed’ self-service portal?

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’.

How do I know if I have a valid noise certificate issued by the Manufacturer or a relevant authority from another country?

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, Cities and Regional Development (DITCRD). An example of an Australian noise certificate is provided below for information.
A noise certificate issued by a country or nation state, and will include full configuration details, the logo of the issuing authority, include a signature and the date the noise certificate was issued.

Engine Emissions Certification

Does Airservices need to confirm my aircraft’s engine emission certification?

Airservices has been delegated by the Department of Infrastructure, Transport, Cities and Regional Development to confirm the engine emission certification status for all aircraft, at the point of an Aircraft Environmental Assessment.

In order to minimise the burden on aircraft owner/operators, this process has been incorporated into the previous Aircraft Noise Assessment process and aircraft will not be required to gain confirmation until the point that an aircraft next requires an assessment to be undertaken.

Do I need to email Airservices evidence of my aircraft’s engine emission certification?

No, in most circumstances it is anticipated that evidence required to support a noise assessment will also be sufficient to confirm an aircraft’s engine emission certification. Airservices will not require or request additional evidence, other than that necessary to support the Noise Assessment process.

The Aircraft Noise Assessment team will use submitted evidence, along with a number of other evidence sources, to verify whether an aircraft meets the Aircraft Navigation (Aircraft Engine Emissions) Regulations 1995.

In situations where the evidence provided by the applicant and assessment team resources cannot confirm an aircraft’s engine emission status, the application will be referred to the Department of Infrastructure, Transport, Cities and Regional Development (the Department) for a determination and the applicant will be notified of the referral. The Department may contact the applicant to request further information.
