The standard we build to

This site is built to meet WCAG 2.2 Level AA. That is a working floor rather than a badge: it has not been independently audited, and saying so is more useful to you than a compliance claim you cannot verify.

Colour and contrast

Every text and background pairing was measured rather than eyeballed. Body text measures 14.36:1 on the page ground. The muted grey used for secondary text measures 5.87:1 on the page and 5.37:1 on the tinted band.

Aviation orange is used as a surface rather than as text. Where text sits on an orange ground it is near-black, measured at 4.90:1; white on that orange measures 3.61:1 and is not used below large sizes. Where orange appears as text it is a darker tone specifically chosen for the ground it sits on: 6.15:1 on the light page, 6.08:1 on steel.

Obstruction red marks a state — a hold point, a stop-work condition, a form error — and is never the only signal. Every marked state also carries a word.

Keyboard

Everything interactive is reachable and operable from a keyboard in a sensible order. Focus is always visible: a two-pixel outline, offset, in one fixed colour that never changes meaning.

A skip link to the main content is the first thing in the tab order on every page. The navigation on small screens opens from a real button with aria-expanded, and Escape closes it and returns focus to the button. Wide tables that scroll sideways become focusable regions so they can be scrolled with arrow keys, and only when they actually overflow.

Screen readers and structure

Every page has one h1 and a heading order that does not skip levels. Landmarks are real: a banner, a primary navigation with a label, a main region, and a footer navigation with its own label.

Rate and schedule tables are real tables with a caption, a header row and row headers, so they are read as a grid rather than as a run of numbers. The elevation on the homepage is an ordered list, so it is announced as a sequence with a position and a length.

The drawing on the homepage is SVG with a title and a full text description: the marking scheme, the lighting levels, the height scale and every keynote are described in words rather than announced as an image.

Decorative elements — the marking band between sections, the rail beside the elevation, the beacon lamp — are drawn with CSS and hidden from assistive technology.

Motion

There is one animation on this site: the obstruction beacon pulses once every four seconds. A real L-864 beacon flashes twenty to forty times a minute; this is slowed deliberately, because a web page is not an aircraft hazard. Everything else is a short fade as a section scrolls into view.

If your system asks for reduced motion, all of it is switched off, the beacon simply stays lit, and the page renders in its finished state. Nothing loops quickly, nothing auto-plays, nothing flashes at a rate that could trigger a seizure.

Without JavaScript

The whole site works. Every page renders, every station on the elevation is present and every link works, the questions open because they are native disclosure elements, the telephone number is a real link, and the footer carries the complete navigation. JavaScript adds the mobile menu, the fade, and the marking of the current station. Nothing depends on it.

Text, zoom and sunlight

Everything is real text; there are no images of text anywhere. Type is sized in relative units, so it follows your browser setting, and the layout holds at 200% zoom and at 400% in a single column without horizontal scrolling.

The light ground is a deliberate choice for this audience: a large share of the people reading this are doing it on a phone, outdoors, in Florida sun. A dark page looks better in an office and is harder to read at a site.

What we have not done

We have not had an independent audit. We have not tested with every combination of screen reader and browser. There is no accessibility overlay or widget on this site, deliberately — those tend to interfere with the assistive technology you have already configured.

Telling us something is broken

Telephone (407) 423-9071, Mon–Fri 7:00 AM–5:00 PM ET. Tell us the page and what happened, and what you were using if you know. We will fix it, and if a fix will take time we will tell you how to get the information another way meanwhile.

If something on this site is stopping you scoping work, telephone and scope it with us directly. The website is a convenience; the project does not depend on it.
