I'm a Navigraph subscriber because I like to keep my AIRAC Cycle up-to-date due to mainly using real world flight plans into the FMC of my Flight Factor 767. But heres the bonus.Navigraph have had an update and now you can see your aircraft moving along STARS/SIDS and airways and even along the taxiways at many airports called moving maps by installing a little utility called Simlink which is all part of the Navigraph Charts interface.
Sep 18, 2018 - It is not beta anymore and includes the simlink with the Charts Desktop. I've read everything available on the Navigraph website. It is installed. Simlink, the software responsible for communicating the aircraft position from the simulator to all of your Charts software, is bundled in the Charts installer and will therefore install automatically.
It's excellent and all free as part of your subscription. For about 8 quid a month I'm not grumbling at all. Most flight simmers with serious Study aircraft will be signed up to either Navigraph or Aerosoft.
