Question 1

Where do I export the SimBrief XML?

Accepted Answer

After generating your OFP in SimBrief, scroll to the Downloads section and click the XML button. Save the file, then upload it here. The file is usually named something like OFP_KJFK_EGLL_XXXX.xml.

Question 2

Is my flight plan data sent anywhere?

Accepted Answer

No. The XML file is read and parsed entirely in your browser using the browser's built-in DOMParser. Nothing is uploaded to a server.

Question 3

Why does the route map not show?

Accepted Answer

The interactive map requires Leaflet to load. If you are on a slow connection the map may take a moment to initialise. It only appears when the navlog contains at least one fix with valid coordinates.

Question 4

Where does the terrain profile data come from?

Accepted Answer

Ground elevation is sampled along your planned route (the navlog fixes, not the direct great circle) using Open-Meteo's public elevation API, which draws from global digital elevation models. It reflects real-world terrain, not in-sim scenery, and is for simulation reference only.
