No, it's own data base that is made to work with add on aircraft that works in FS.In other words add on aircraft (payware usually) companies use this navdata for their FMC's.Users like you and I can update this data regularly for a very small fee in the case of Navigraph and have fairly good coverage for what we need, and install it into which ever addon(s) we have.
