Kittie:FSNav is an ingenius utility. It's impossible NOT to build a flightplan successfully. You need to see it and experiment with it first. It's design is brilliant: made for experts and idiots alike; you cannot go wrong using it -- period.First, enter you origin runway and your destination runway by clicking and dragging them from the moving map into the flightplan window. Then generate a flightplan, either automatically or manually. You can drag waypoints from the moving map into the flightplan or "auto-generate" the rest of the plan, i.e., let FSNav build it for you as efficiently as it can figure to do so. There are several ways you can build flightplans and you don't need to be expert with aviation charts. That said, be aware that you DO need to pay attention to altitudes and elevations so you don't build a flightplan that takes you into a mountain face !FSNav has got nice HELP features and everything is explained neatly and concisely.There are some features everybody should be aware of with later versions. Most notably, the approach speeds indicated in the flightplan for jet flight below 10,000' are largely erroneous. You will appear to be set up for extremely fast approaches. The speed indications are incorrect. But if you allow FSNav to control your speeds (a good way to handle this utility) FSNav will in fact slow you down from IAS 240 or 250 by 10 knots per 1000 vertical feet below 6000 to 6200 feet all the way down to your landing.Also, FSnavigator is NOT designed to land you. It is designed to help you join the ILS at a reasonable altitude. On some occasions, FSNav has actually landed me successfully, but such landings are lucky events and it's not supposed to do that (!)FSnavigator also has a built in Flight Management System that is outstanding. It's not as rich as an FMC in a PSS or PMDG aircraft, but it is great for plotting, planning, and learning with the FSNav moving map. I've learned a huge amount by using FSNavigator. You can also build plans with FSNav and export them to FS2004 and to various other commercial FMCs with PSS and PMDG aircraft.Hope this assists further.JS

FSNaviagaor is a great tool. I did not read in detail all of the replies that are posted above, but did anybody mention that a small grouping of updated SIDS/Stars data files are available for update? They appear to have been posted in November/December. To download, select options from the FSN Menu to download into your operating system. Also that monthly AIRACs data file uploads are available at: www.navdata.at/Tom
