Jeppesen FliteStar is not a good idea unless you are general aviation. It is very inaccurate in calculations, it have no ideas how to go overseas (you cannot automatically build the navlog from Europe to North America), usually it creates stupid routing over any sea trying to keep very close to the land and so on. Sometimes you may find that the route is build using one-way airways in wrong direction. Actually to make any reasonably long flight using this flight planning software you need manually make the routing by printed Jeppesen charts and then enter the data into FliteStar - then it is ok. Also there is no interface to send flight plans by SITA or AFTN - printout only.. .Advantages - very low cost (tageted to general aviation and Piper/Cessna-class aircraft), and Corporate version is not very different.
