The dev team have recently added an example app that display the data within a ARINC 424 navigation database file. The app is written using Microsoft Visual Studio targeting Windows OS using .NET 8.x and the Windows App SDK.
The app has a split pane and will display the ARINC 424 records in a tree view with the number of records that will appear when the tree is expanded. The the full details of the ARINC 424 record are displayed in a grid of two columns showing the field name and the field value of the navigation data.
