How manual sections are mapped to regulations
The accuracy of regulation change impact assessments depends on how well your manual sections are mapped to the underlying regulations. Flight Lyceum does this automatically using semantic embeddings, but you can improve it manually.
How automatic mapping works
When your manual is indexed, each section is converted into a vector embedding: a mathematical representation of its meaning. These embeddings are compared against the embeddings of each regulation to find semantically similar passages.
Tip: This approach catches regulatory references that aren't explicit citations. For example, a section titled 'Pre-flight checks' will be linked to relevant Part-FCL requirements even if it doesn't mention 'FCL.050' by name.
Viewing section mappings
You can view the regulatory mappings for any manual section from the Flight Books browser.
- 1Open a flight book.
- 2Click on any section.
- 3Scroll to the Regulatory references panel on the right.
- 4The panel lists every regulation that the section is mapped to, with a confidence score.
Adding explicit regulation citations
The most reliable way to improve mapping accuracy is to add explicit regulation references within your manual text. Citations in the format 'FCL.050', 'ORA.ATO.100', or 'AMC1 FCL.050' are automatically detected and create a direct mapping: stronger than a semantic match.
Tip: Many EASA-compliant ATOs already include regulation citations in their manuals. If yours doesn't, adding them is good compliance practice regardless of Flight Lyceum.
Correcting a mismatched section
If a section appears to be mapped to an irrelevant regulation, you can remove the mapping manually.
- 1Open the section detail view.
- 2Click the X next to the incorrect regulation mapping.
- 3Confirm the removal.
- 4The correction is saved and used when future changes to that regulation are assessed.
Sections with no mappings
Some sections (administrative front matter, definitions, list of amendments) may have no regulation mappings. This is expected. These sections will not generate review queue items when regulations change.
