Civil Aviation Authority is committed to ensuring digital accessibility for people with disabilities. We are continually improving the user experience for everyone, and applying the relevant accessibility standards. This statement was prepared on 28th May 2020.

Conformance status

The Web Content Accessibility Guidelines (WCAG) defines requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. The Airspace Change Portal is partially conformant with WCAG 2.1 level AA. Partially conformant means that some parts of the content do not fully conform to the accessibility standard.


We welcome your feedback on the accessibility of the Airspace Change Portal. Please let us know if you encounter accessibility barriers on the Airspace Change Portal:

Technical specifications

Accessibility of the Airspace Change Portal relies on the following technologies to work with the particular combination of web browser and any assistive technologies or plugins installed on your computer:

  • HTML
  • CSS
  • JavaScript

These technologies are relied upon for conformance with the accessibility standards used.

Limitations and alternatives

Despite our best efforts to ensure accessibility of the Airspace Change Portal, there may be some limitations. Below is a description of known limitations, and potential solutions. Please contact us if you observe an issue not listed below.

Known limitations for the Airspace Change Portal:

  1. Potentially affected area: The potentially affected area of an airspace change may not be perceived by blind and visually impaired users because it is communicated in the form of a shape overlaid on a map. To address this issue, we will provide a text alternative to the map content by September 2020. In the meantime, please contact the sponsor associated with the airspace change in question, for further details of the potentially affected area.
  2. PDF documents: Many supporting documents associated with the various airspace change proposals are not correctly structured or tagged for accessibility. The documents in question are provided by the individual airspace change sponsor organisations. Please contact them directly to request the content in an accessible format.

Assessment approach

Civil Aviation Authority assessed the accessibility of the Airspace Change Portal by the following approaches:

  • Self-evaluation

Formal complaints

Please contact the Equality Advisory and Support Service (EASS) if you're unhappy with our response.
