FsNav is great for something visual you can refer to in Fs9. But for PLANNING a standard route, I always use vRoute with updated airac cycle. It has most of the commonly used routes and can access charts, as well as give route distance, help with fuel planning, suggest scenery for the airports, provide current weather metars, and alot of other information regarding the 'planning' of the flight... Yes its usually a tool used for Vatsim folks, using a Vatsim sign-on, but its free and thats the best in its pricerange ;)I use vroute daily for planning, and use FSNav inside FS9 for info regarding navaids, and numbers quickly.... charts can be pulled up from vroute, and/or from myaiplane.com directly.
