I am a Linux user, and I use the Navigraph Charts webapp. I am unable to use SimLink, don’t get the moving maps feature in Charts, and had to install the nav data by hand. My question is, if I don’t have SimLink installed, does the nav data do anything? If so, what does it actually change within the game? ---

The Navigraph Navdata Update updates the navdata in your simulator to the latest available. ---

Thank you. My question is, what effect does the navdata actually have on the sim? ---

Hi, Nothing much really. If you are using X-Plane it does affect the navdata and will update it for all aircraft using the X-Plane standard navdata. ---

I appreciate your replies, but it doesn’t answer my question. The question is, what is the functional impact, within the simulator, of updating the navdata? In other words, what _is_ navdata? ---

Every road, cycle lane, footpath on google maps is Google Maps Nadata. Same thing in aviation. navigraph provides accurate and up to date airways, waypoints, procedural routings and much more. ---

That makes a bit more sense, thank you! ---
