The Aviation Safety Letter (ASL) is going through some changes. Previously, the ASL was only available in PDF, but starting with issue 3/2019, it’s now also available in HTML . This change makes it easier to share articles with others—but more importantly, will make it easier to search for specific topics.
You’ll notice that the ASL’s look has been updated. If you receive an ASL e-bulletin notification email, you’ll soon find an improved email with links directly to content. If you aren’t subscribed, we encourage you to sign-up online.
