Implementation of Performance Based Navigation – Guidance for Pilots

The CAA have published Information Notice IN–2017/034 which gives further information on the implementation of European Commission Regulation (EU) No. 539/2016 Performance Based Navigation (PBN) that amends European Commission Regulation (EU) No. 1178/2011 (the Aircrew Regulation).

The new PBN regulations will require:

That from 25 August 2018 pilots may only fly in accordance with PBN routes and procedures after they have been granted PBN privileges as an endorsement to their Instrument Rating (IR);

All pilots with an IR or Enroute Instrument Rating (EIR) will need to have PBN privileges after the 25 August 2020.

Applicability for Flight Crew

The UK CAA has adopted a PBN declaration process. To obtain a PBN endorsement pilots have two options;

1. Undertake PBN IR theoretical knowledge and practical training at an Approved Training Organisation (ATO), which includes passing a theoretical knowledge examination prior to passing a Skill Test or Proficiency Check which includes the applicable PBN IR elements with an examiner authorised to conduct such test or check; or

2. Make a declaration confirming that the pilot is sufficiently familiar with PBN operations, including the theoretical knowledge elements. Also pass an oral theoretical knowledge assessment prior and in addition to, passing a Skill Test or Proficiency Check which includes the applicable PBN IR elements, with an examiner authorised to conduct such test or check.

A copy of the PBN declaration form is included in Appendix 1 to this Information Notice. This form must be printed and completed by the applicant prior to attempting the oral theoretical knowledge assessment and the Skill Test or Proficiency Check.

Examiners should refer to IN 2017/026 , for guidance on their authorisation process.

Undertaking Training at an ATO

If the pilot attends an ATO, either UK or non-UK approved, the pilot must ensure that all training undertaken is conducted at an ATO that holds an approval to conduct instrument training and has updated their syllabus to include the PBN elements.

The pilot must retain a copy of the course completion certificate issued by the ATO, along with the PBN declaration form and must provide these as evidence to the examiner prior to attempting the Skill Test or Proficiency Check.

Copies of these forms, together with the Examiner’s Report, must be submitted to the CAA.

Examiners must retain a copy and the CAA recommends that the pilot also keeps a copy.

For non-UK certificated examiners please refer to IN 2016/003 for further guidance.

Making a Declaration of PBN Familiarity

All pilots are reminded of their responsibility to ensure that they are capable of operating at an appropriate level of competence in PBN operations prior to operating on routes or procedures that require use of RNAV systems to meet PBN navigation specifications.

A list of the areas of knowledge is included in Appendix 2 of this Information Notice. Pilots should ensure they are sufficiently familiar with all of these areas, when making the PBN declaration.

The pilot must present the PBN declaration form to the examiner at the time of undertaking the oral theoretical knowledge assessment. This must be prior to attempting the skill test or proficiency check. The content of the oral assessment is at the discretion of the examiner but will cover the areas of knowledge in Appendix 2 of this Information Notice.

The oral assessment may take up to 2 hours. Failing the oral element test may mean that the flight test is failed or partially failed prior to the flight element taking place.

A copy of the declaration form and the Examiner’s Report must be submitted to the UK CAA. Examiners are required to retain a copy and the CAA recommends that the pilot also keeps a copy.

Pilots Currently Undertaking IR Training

For pilots currently enrolled on an integrated or modular course the theoretical knowledge examinations will be revised to include the necessary PBN knowledge. Any candidate having passed examinations including this revised syllabus will not need to complete the course /oral assessment described in this Information Notice.

Please refer to IN 2017/028  for further guidance.

Third Country Licence Holders

Holders of ICAO compliant licences issued by third countries wishing to obtain an EASA IR by the existing conversion methods will need to become PBN qualified. The above PBN arrangements therefore apply. However, the licence conversion process will involve an oral element to demonstrate knowledge of the topics set out in Part-FCL. At the discretion of the examiner knowledge of these topics evidenced by a course completion certificate from an ATO may be taken into account.

Please refer to Information Notices IN 2017/016 and IN 2017/029 for further guidance.


A pilot planning to make an application for any licence, rating or certificate at the same time as applying to obtain a PBN endorsement, the appropriate course completion certificate and Examiner Report indicating that the PBN elements have been completed must be submitted along with the appropriate application forms for the licence, rating or certificate being applied for.

If the applicant is not applying for any other licence, rating or certificate, then after the completion of any training, if applicable, or making the declaration and passing the oral assessment and Proficiency Check, the pilot does not need to apply for the issue of the PBN endorsement on to their licence.

On successful completion of the Proficiency Check the examiner must sign the pilot’s Certificate of Revalidation within their licence with PBN endorsement in the following format:

Example:    B737IR/LV/PBN
                     IR SPA ME PBN

The appropriate Examiner Report Form must be clearly marked in Section 2 with the following:

‘Instrument Rating Includes PBN Endorsement’

The UK CAA will update the applicable forms taking into account the above changes. The Flight Examiners handbook and Standards Documents will also be updated.

UK Instrument Meteorological Conditions (IMC) or Restricted Instrument Rating (IR(R))

The UK CAA will issue further information via Skywise on the impact of the PBN regulations on the IMC/IR(R) Rating and update Standards Document 25, later in the year.
