Little Navmap and Airac question?

Hi there, How do I update the Airac in Little Navmap? Any help is greatly appreciated. Thanks in advance.

I’m not aware of any other way to update the LNM AIRAC other than a Navigraph subscription. Assuming you have such a subscription then the FMS Data Manager app will do it automatically.

LNM actually reads the MSFS sim NavData - autodetects it, so with only LNM and the sim, what you’re seeing is the NavBlue database.

If you install Navigraph data, into the sim, LNM will read that instead of the NavBlue.
