Noise exemptions: guidance notes for applicants for an exemption under Regulation 25 of the Aeroplane Noise Regulations 1999

Noise exemptions are granted only in tightly defined circumstances.

An application for exemption must be accompanied by any supporting justification the applicant may wish to offer. (Please note that an exemption will not be issued where the flight could reasonably be operated using a Chapter 3 compliant aircraft, even if, for example, the Chapter 3 compliant aircraft will cost more to charter or has a capacity or payload greater than needed.)

 In particular, the application should specify:

(a) details of the flight(s)
(b) aircraft type, registration and operator
(c) why a Chapter 3 compliant aircraft cannot be used (if the reason is lack of availability, evidence should be produced of efforts to source a Chapter 3 compliant aircraft)
(d) whether the UK airport concerned has been consulted.

and, in the case of urgent relief flights:

(e) on whose behalf each item of cargo is being carried (eg aid organisations)
(f) a brief description of each item of cargo

Consultation with DfT

Before granting an exemption the CAA is required to consult the Secretary of State.  The CAA is also likely to consult with the Department for Transport in cases where the CAA is not convinced that an application fully meets the criteria for exemption.

Grant of an exemption

The grant of any exemption will be on the public record.  No passengers or cargo may be carried for hire or reward on positioning sectors.  The exemption will specify a date and UK airport for each flight, and will usually be limited to the hours 0830 to 2030 local time.  A copy of the exemption should be carried on the flight deck at all times.  In the case of an urgent out-of-hours application, the exemption will be authorised by telephone under a unique reference number.
