From time to time, we'll issue 'CAA Notices' to ensure that we remain responsive and adaptable to changes or emerging risks in the civil aviation system.

Proposed Notices

There will be consultation for all new CAA Notices and amendments. See the Rule projects in progress page to find out about upcoming rule projects, which may include CAA Notices.

Proposed Notices open for submission

Current Notices

Introduction

The regulatory framework has recently undergone some changes to provide clear, effective and workable requirements for carrying out PBN operations. There are three main parts to the regulatory framework:

  1. Civil Aviation Rules 91.261 and 91.263 require operators and aircraft carrying out PBN operations to comply with technical and operational requirements, which are specified by the Director in Civil Aviation Notices.
  2. Civil Aviation Notices, which set out detailed technical and operational requirements for each individual navigation specification. The Notices also prescribe where CAA operational approval is required.
  3. Advisory Circular 91-21, which provides operators with an acceptable means of complying with the requirements set out in the Rules and Notices.

16 PBN Notices have been finalised and signed by the Director. They came into effect on 21 December 2022. Each PBN Notice provides the technical and operational requirements for a specific navigation specification. For example, PBN Notice RNP 2 specifies the requirements for performing RNP 2 operations.

The content of the notices is aligned, as closely as practicable, with the required elements for each navigation specification set out in ICAO Document 9613: Performance Based Navigation. The notices also prescribe where specific approval from the Director is (and is not) required to carry out a flight using a given navigation specification. Operators will still need to comply with Civil Aviation Rules where applicable, such as Part 91.

A summary of the approval requirements is set out in the table below. Note that ‘Nil’ means CAA specific operational approval is not required.

Part 91 non-certificated operators

For each navigation specification, the minimum requirement is that the operator complies with all the applicable requirements of the PBN notice. This is much like the majority of Part 91 operations compliance responsibility which rest with the pilot-in-command or operator. No specific CAA approval is required except for RNP 0.3 and RNP-AR operations, where a Part 91 PBN operational Letter of Approval (LoA) is required.

Part 119 certificated operators

The following navigation specifications require CAA approval:

RNP 10, RNP 4, RNP 2, RNP 1, RNP APCH (LNAV & LNAV/VNAV), RNP APCH (LP & LPV), A-RNP, RNP 0.3 and RNP-AR.

Part 129 certificated operators

The following navigation specifications require CAA approval, based on the foreign NAA regulatory approvals:

RNP 10, RNP 4, RNP 2, RNP 1, A-RNP and RNP-AR.

3 Non RNAV/RNP designated GPS procedures & PBN Operations with a Part 19D operational approval

This PBN notice will expire on 21 December 2024, 2 years from the commencement date of the notice.

Applications for operational approvals currently in process with CAA

These will be assessed as per the requirements above. Where CAA operational approvals are not necessary, the CAA will not assess and approve these specific operations.

If you have queries or concerns related to your operational approval application, please email us at certification@caa.govt.nz

When the PBN draft notices were on the CAA website for consultation, a draft new revision of AC61-17, Pilots License and Ratings – Instrument Flight ratings, was also up for consultation. Among other changes, this revision makes changes to Appendix I to update the IR theory and practical syllabi to include PBN as the foundational knowledge and training requirement.

Although the new revision of AC61-17 will not be published until the middle of 2023 when the syllabus is updated, Appendix I can be found here [PDF 611 KB] in a clean copy and here in a marked up [PDF 688 KB] copy. This is provided for information, to enable flight training providers to amend their training material to prepare for the new syllabus.

There is also more general guidance on PBN in AC91-21 - Operational Approvals - Performance-Based Navigation.

Where do CAA Notices come from?

Section 28(5) of the Civil Aviation Act 1990 enables the Minister of Transport to make rules that “empower the Director, the Authority, or any other person” to issue approvals, determinations, requirements, conditions or procedures for purposes specified in the rule.

This provision was inserted into the Act in 2010 in order to create some flexibility to allow the aviation regulatory framework to better meet the demands and challenges of the fast-changing aviation sector.

Where the Minister makes a rule under 28(5), he or she could allow for approvals, determinations, or requirements to be set out in an additional document, which can be more readily amended in future.

We call these documents 'CAA Notices'.

What will CAA Notices contain? What will they look like?

CAA Notices could include, for example, the technical specifications for equipment or technology required to support a performance based rule, procedures for training, or conditions associated with the use of an aircraft or other aviation product.

They will have a similar look and format to Advisory Circulars (ACs).

How are CAA Notices different to the rules?

Where the Minister approves a rule that allows for the use of CAA Notices, that rule will set out the objectives, criteria for consideration and procedures to follow, as appropriate, for developing the Notice. The rule will require compliance with the Notice. The Notice will then list the specific detail, for example technical standards or training conditions.

Once the rule is in place, CAA Notices can be developed and amended more rapidly than rules.

What are the benefits of CAA Notices?

CAA Notices offer a number of benefits, including:

Supports performance based regulation

Section 28(5) facilitates the development of performance-based rules by enabling the inclusion of specific mandatory technical requirements and procedures in something other than the rules. A performance-based rule would set out the high-level requirements and the outcomes sought. CAA Notices made under that performance based rule would then be used to provide the specific details of what must be done in order to comply with the primary obligation, where this is necessary.

More adaptable to technological changes

CAA Notices will enable aviation regulation to be more responsive to changes in technology. The Director or Authority will be able to modify technical specifications, impose conditions on the use of emerging technology, or permit new activities without undergoing the entire rule development process, where the rule allows it.

More responsive to immediate safety issues

CAA Notices could be used where there is a need to make determinations, or impose requirements or conditions for extraordinary safety reasons. Amendments to existing rules may not address the issue with sufficient speed and may not be able to adapt to the changing nature of the risk.

Can reference specific operations and equipment

CAA Notices can also be used to supplement the rules by enabling the CAA to address specific safety risks posed by, for example, particular equipment or operations. Requirements specific to a particular make of aircraft would not generally be considered appropriate for inclusion in a rule.

How are CAA Notices different to Advisory Circulars?

CAA Notices will have a different function and effect to ACs. ACs detail possible non-mandatory means for achieving compliance. CAA Notices specify details that must be complied with.

ACs are advisory in nature and provide advice, guidance and information. They advise on acceptable means of compliance with the legislation and other good practice, without limiting other acceptable ways of doing so.

How are CAA Notices different to Continuing Airworthiness Notices?

A Continuing Airworthiness Notice (CAN) is unrelated to CAA notices. The CAA will issue a CAN to bring industry attention to an ‘airworthiness concern’ in the interests of aviation safety, and contains information and guidance about an airworthiness concern that does not meet the criteria for an Airworthiness Directive (AD). A CAN is intended to alert, educate, and make recommendations to the aviation community.

How will CAA Notices be developed?

The enabling rules will define the scope of the power under which CAA Notices will be issued. The CAA Notices will be made within the limits set out in these authorising rules.

The enabling rules will also provide a procedural framework for issuing CAA Notices, for example, requiring consultation and publication, and a process for amendment and revocation.

The development of Notices will follow normal policy development processes (problem identification and definition, options analysis, consultation, and evidence-based decision-making).

Will I have chance to comment on a CAA Notice before it comes into effect?

CAA Notices will be consulted on as appropriate. When initially developed as part of a new or amended rule, CAA Notices will be part of the Notice of Proposed Rule-Making (NPRM) process to the extent appropriate.

CAA Notices will be readily and freely available for public access and published on the CAA's web site.

Has section 28(5) of the Civil Aviation Act been used before?

There are already examples of rules that provide the Director or the Authority with the ability to establish mandatory requirements.

For example, Subpart AA of Part 139 sets out the framework within which the Director can make a determination as to whether an aerodrome requires a qualifying operator certificate. Rule 139.23 requires the Director to consider aerodrome aeronautical safety data as part of the determination.

Do other countries use Notices?

We are not the first country to use a tool like this - comparable aviation regulators sometimes set out requirements in places other than the rules. For example, the Australian Civil Aviation Safety Authority (CASA) uses Civil Aviation Orders and Manuals of Standards. Civil Aviation Orders are made by the Director of Aviation Safety for a wide variety of activities, contain detailed technical requirements, and generally supplement Civil Aviation Regulations. Manuals of Standards include detailed technical requirements and support the implementation of the Civil Aviation Safety Regulations.
