After wasting much time trying to locate sectional charts for FS 2002, which I still can't find, I located a Web site that contains all the charts you need; Instrument Approach, VORTAC, Airport Diagrams, etc... I just bring up on my PC and leave it on while I'm flying so I can refer to it s needed. The charts are big and clear. sample chart here - http://media.sportys.com/hires/publishe ... 982G16.PDF
Have you tried the FAA website? They have real world charts there for free to print in PDF format. I don't know if there is anything that you can bring up while you fly but printing is the next best thing.
