I concur with the recommendation for X-Plane. if you have an older PC you can run an older version that is less demanding but will still do the job. With X-plane you can download the full version, it will run in demo mode for 10? minutes and then you have to restart the program; this allows you to see if your installation is working on your PC (WIN, Mac or Linux). I started somewhere with version 6 and now version 9 which does everything I require, mainly IFR procedure training.
