Yesterday I posted about a small utility that parses and explains ARINC 424 records. I have updated it.

For each field, the tool now cites the specific tables in the ARINC 424 specification that describe that field. The field-content explanations are also more detailed, so you can spend less time flipping between the parsed output and the printed standard. Here is an example for an Airport SID/STAR/Approach primary record:

This is still a work in progress. Not all record types are supported yet; I am filling those in as I need them.

The code remains at arinc424_explainer. Contributions are welcome — feel free to open an issue or pull request. If you have questions or run into trouble, see my contact page.
