Heading Hierarchy
6 headings
REVIEW
6 headings
Critical::
No H1 heading found
Every page should have one H1 that describes the page content.
  • H5 User account menu
  • H5 User account menu
  • H2 Strategic Goals
  • H2 News & Highlights
  • H2 Global Air Traffic Snapshot
  • H2 Use of personal data and cookies

Every page should have one H1 that describes the page content.

Why this matters

No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.

Learn more ▾

The H1 is the document title for assistive tech and a strong signal to search engines about page topic. Pages without one force screen readers to fall back to the <title> attribute or page chrome. Add a single H1 that names the page's primary subject.

1 contrast failures on background images/gradients

These failures are invisible to CSS-based accessibility tools like Lighthouse. The text may be fine on a solid background, but fails when rendered over an image or gradient.

Methodology: The top 20 text elements by font size were checked. Background color was sampled from the desktop screenshot using a 5-point pattern. WCAG 2.1 AA requires 4.5:1 for normal text and 3:1 for large text.

Page Structure — as a screen reader sees it
BANNER header NAV MAIN CONTENTINFO footer

Multiple navigations need aria-label to distinguish them for screen readers.

Why this matters

Some <nav> elements lack aria-label — screen-reader users hear 'navigation' multiple times with no way to distinguish them.

Learn more ▾

When a page has multiple <nav> regions (primary, footer, breadcrumb), each needs aria-label or aria-labelledby. AT users navigate by landmark; identical 'navigation' announcements force them to enter each one to discover purpose.

Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

<input type="submit" id="edit-submit-icao-search">

Why this matters

Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

Names and labels

Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn how to make links accessible.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
div > div.card-item > div.featured-card > a.card-link-wrap div > div.card-item > div.featured-card > a.card-link-wrap
div > div.card-item > div.featured-card > a.card-link-wrap div > div.card-item > div.featured-card > a.card-link-wrap

These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
