It is vital that CAP 1724 Flying Display Pilot Authorisation and Evaluation: Requirements and Guidance remains up-to-date and relevant, and that the CAA’s guidance material in these areas remains proportionate, clear and unambiguous.

We asked for feedback from the regulated community on proposed amendments to CAP 1724 ahead of the 2026 display season. 

We compiled a draft of CAP 1724 Edition 8 and consulted on it over four working weeks from 05 January 2026 to 30 January 2026. 

We received a total of 43 unique comments to the draft CAP 1724 from 8 respondents.  

Of all the comments, 18 clearly conveyed some sort of change and 25 were either  unclear / not specific or suggested no changes, some being purely comments.  46% of all the comments supported the proposed amendments.

Of the 18 conveying a change, 9 were textual in nature, suggesting revised wording or highlighting minor drafting / clarification points, 2 being duplicated between respondents.  The other 9 comments were more substantive, calling for some sort of change of the underlying policy. 

We accepted 13 of the 18 comments suggesting some sort of change (72%).  8 of these comprised of rewording content or the addition of further information for additional clarification, we have tried to take a balanced view on what would be helpful.  Of the remaining 5, 4 concerned minor policy changes and 1 concerned an underlying policy change that will require further DAE consultation before any implementation.

Of the remaining 25, 5 were unclear / not specific whilst the remaining 20 expressed support for the changes.

Regarding the 6 comments suggesting some sort of change that were not implemented, 1 concerned a grammar issue (spelling) that we were unable to locate, 3 concerned sensitive text that we are unable to change due to further unintended consequences and 2 concerned underlying policy beyond the scope of CAP 1724.

We have produced a final version of CAP 1724 Edition 8 which was published on 9 March 2026. 

It is vital that CAP 403 Flying Displays and Special Events: Safety and Administrative Requirements and Guidance remains up-to-date and relevant, and that the CAA’s guidance material in these areas remains proportionate, clear and unambiguous.

We asked for feedback from the regulated community on proposed amendments to CAP 403 ahead of the 2026 display season. 

We compiled a draft of CAP 403 Edition 23 and consulted on it over four working weeks from 08 December 2025 to 02 January 2026. 

We received a total of 43 unique comments to the draft CAP 403 from 11 respondents.  

Of all the comments, 30 clearly conveyed some sort of change. 13 were either unclear / not specific or suggested no changes, many being purely comments.

Of the 30 conveying a change, 25 were textual in nature, suggesting revised wording or highlighting minor drafting / clarification points, 6 of the 25 were duplicated comments concerning 2 specific topics.  The other 5 comments were more substantive, calling for some sort of change of the underlying policy. 

We accepted 18 of the 30 comments suggesting some sort of change (60%).  These changes comprised of rewording content or the addition of further information for additional clarification, we have tried to take a balanced view on what would be helpful. 

Of the remaining 13, 9 expressed support for the changes, 3 were unclear / unspecific and 1 was based on an inaccurate / incorrect understanding of the regulation. 

We were unable to implement any of the 5 more substantive comments we received.  1 was a comment concerning a matter beyond the scope of CAP 403, 1 was based on an inaccurate / incorrect understanding of the regulation and the remaining 3 concerned suggestions for unacceptable changes to policy or may involve unintended consequences if implemented.

We have produced a final version of CAP 403 Edition 23 which was published on 09 February 2025. 

For comments on the proposal that the CAA introduces an equivalent safety finding concerned with removal of some indications from the primary flight display during ground phases, when using a 3D Airport Moving Map (AMM) feature.

The UK CAA is consulting on an Equivalent Safety Finding that is applicable to CS-23 Normal Category Aeroplanes.

This Equivalent Safety Finding provides the compensating factors to reach an equivalent level of safety to direct compliance with CS-23 23.1303, 23.1311(a)(3) & 23.1321(d).

The Consultation Paper Equivalent Safety Finding UK.ESF.F.0003 Issue 1 provides the full detail of the identified issue, and the associated Equivalent Safety Finding.

We received 1 response.

This response highlighted the importance of preventing erroneous activation of the 3D Airport Moving Map (AMM) feature and highlighted potential failure effects of the AMM feature and the aircraft’s GPS system.

We acknowledge the response and thank the responder for their suggestion.

The comment is not incorporated. CAA consider that this comment is addressed by the following mitigations detailed in the Equivalent Safety Finding Consultation Paper UK.ESF.F.0003 Issue 1:

• If the indication is failed while removed (e.g. failure of the bank and pitch information when not displayed), the corresponding alerting is as efficient as when the indication is available.
• Mitigations have been put in place to compensate for the reduced exposure of flight crew to failures that may not be detected by the systems (e.g. frozen heading and airspeed on both sides).
• If the removed indication fails to be displayed when required or is erroneously removed during other flight phases (e.g. in cruise), the failure effect and compounding effects meet all applicable certification specifications.
• Appropriate procedures when needed to ensure Continued Safe Flight and Landing and to recover the removed information are introduced in the Aeroplane Flight Manual.
