The ARINC424 Editor is a Windows desktop application that will read an ARINC424 navigation data file (if available), or load a single ‘saved’ procedure, or build/edit a procedure in the ARINC 424 navigation file format and save.

The editor supports most ARINC424 record types and, once loaded, displays the data in a hierarchical manner. The editor supports versions 18, 19 and 20 of the ARINC424 specification.

For some record types, the data may be displayed in a geographic context.

When modifying data, the editor constantly validates your input to ensure that incorrectly formatted data cannot be created. In the following example the Displaced Threshold Distance is outlined in red as the ARINC424 specification requires that 4 characters be provided, and only 3 have been entered.
