I have just installed the iFly Boeing 747-400 V 1.1.0.0.created by the IFly Developer Team. In the read me it recommends that the Navigation Database and the Sid/Star Database be updated. It would be much appreciated if someone could tell me how to go about acquiring the correct files and then exactly how to install them. I am still not too sure when adding files to FSX, just need a little hand holding.Bob

Welcome to Avsim Bob.Check out this link where they outline the procedure for updating the Navigational Database.http://www.fsdownload.com/modules.php?name...article&sid=603About halfway down the page it says "We recommend to update the navigation database from http://www.navdata.at, we use the same database as pic767/pmdg737. We also recommend to update the SID/STAR database from http://PlanePath.comI haven't had a look at this page but there will probably be some installation instructions which you can follow.I've found that it's usually not necessary to update the database to get the aircraft flying anyway. It's only required when you intend to fly the sort of published procedures flown in real life.Good luck.Mike.
