This extension makes use of the
flightplandatabase API. Without an API key, you can make 100 daily queries to this API. With an API key, your daily limit is increased to 1500.
You can generate an API key by first creating an account, then going to
settings under API Access.
To input your API key to this extension, in the top-right of your browser, click "Extensions", then click "Navaids For Simbrief". Paste your API key into the box and click save.
If you choose not to use an API key, the query limit of 100 is placed on your IP address.
The key you paste into the box stays on your machine and is only attached to the API request.
