Over 2 years promising to add custom LNAV/VNAV capability, still not there. Nice shor-hauler, but the product is currently using a default FS database, which is very limited in capability to modify/edit routes, arrivals etc. If/when FSS release an update, it could be a good product, but for now, I don't recommend it.
I live near providence and this is a very accurate rendition of the airport and surrounding buildings. Lot's of details without killing the PC performance. Excellent job by the developers. For a long time, TF Green was neglected by the scenery designers, and this ended with this release. Buy it with confidence. As far as those users who left one or two stars, none of those reviews make any sense to me, all I can say to them is... "get a life" LOL.
