Hi
I’m currently working on adding support for a missing airport in the Fenix A320 (using the navdata files located at C:\ProgramData\Fenix\NavData). The aircraft doesn’t natively support this airport, so I’m manually building a custom navigation database entry using the latest AIRAC cycle.
I’ve been able to extract and correctly structure most information (coordinates, runway data, transitions, waypoints, etc.) using the SQLite database from Navigraph’s navdata folder. However, I’m stuck on one key issue: I need to obtain the correct frequencies and channel numbers for the following Navaids:
- ILS (including LOC frequency and course, as well as the Channel Number used by the Fenix)
- VOR (frequency and ICAO code)
- NDB (frequency and identifier)
The Fenix navdata format expects ILS channels in a converted 25kHz numeric format (e.g., 108.90 MHz becomes 17338368), and I want to ensure I’m extracting accurate, authoritative data directly from Navigraph sources.
I have already contacted Fenix developers, and they made it clear that they do not support the custom editing or use of navdata files. They told me to refer to Navigraph
My questions:
- Where exactly can I find ILS/VOR/NDB frequency data in the SQLite database provided by Navigraph?
- Is there a recommended way to calculate or convert ILS frequencies into the Fenix A320’s expected numeric channel format?
- Are there any limitations or guidelines when creating new Navaid entries to avoid breaking compatibility with the Fenix A320’s systems?
