Currently in beta:
https://siteapps.caa.co.uk/g-info/Allegedly to provide a better mobile-interface but reading between the lines it seems more designed to block automated querying.
Some drawbacks1. Query entry page depends on Javascript so actually less browser-agnostic than the old version
2. Frequent and prolonged Google Recaptcha quizzes during sessions. Just now I had to do
fourteen different Recaptchas in a row and then accidentally clicked on the background page and had to start again

3. Can no longer directly link to a particular registration*
Some advantages1. Does require less zooming on mobile but a lot more scrolling, on my phone I can't even see the results without scrolling-down past the big CAA header and other guff.
* Though you can link to the pre-1986 PDFs e.g. for
G-ATULProgress is great but only when it makes progress.
