All the terms you need to know when you’re trying to understand document management.
A List of Effective Pages (LEP) is a key component in aviation manuals that provides a complete list of all the pages in a document, along with their respective revision numbers or dates. Its primary purpose is to help users quickly verify whether they have the most up-to-date and approved version of each page.
Typically found at the front of a manual, the LEP includes:
Page numbers or ranges
Current revision number or date
Optional remarks (e.g., changes made)
The LEP plays a vital role in regulatory compliance, especially during audits or inspections, as it ensures traceability and accuracy across technical documentation.
With Web Manuals, the LEP is automatically generated and updated as pages are edited or revised. This eliminates the manual tracking process and reduces the risk of using outdated content. It also contributes to a faster and more accurate compliance review, giving users and regulators confidence in the integrity of the documentation.
In regulated environments like those governed by EASA, FAA, or CASA, having a reliable LEP is not just best practice—it’s often a regulatory requirement.
