Accessibility statement

We want this reference guide to be usable by as many people as possible. Our target standard is WCAG 2.1 level AA.

What is implemented

Semantic HTML throughout, with a proper heading hierarchy, lists and real data tables with header cells.
Full keyboard operability, a visible focus outline and a skip link to the main content.
Contrast of at least 4.5:1 for body text; information is never conveyed by colour alone.
Alternative text for informative images; purely decorative images are marked as such.
Language is declared per page and on the language switch so screen readers pronounce content correctly.
Text can be enlarged to 200 % and the layout stays usable; no forced screen orientation.
No auto-playing media, no flashing content, and prefers-reduced-motion is respected.

The generated maps are graphics. Everything they show (position, runways, distances) is also available as text and tables on the same page.
Very long tables (such as complete code directories) scroll horizontally, which can be tedious on small screens.
Third-party advertising material is outside our control.

If you encounter a barrier, please write to us: (set the contact e-mail in the admin area). We will fix it promptly.
