I fly a PA31 w/ a Garmin 530, and it is capable of any RNAV approach. If the sim is the same as the real thing, then you should have no problem! An RNAV approach, is very simply, a matter of navigating to certain intersections on the approach , and descending to the required altitude at each intersection or "fix". Just as Nexus stated, you WILL need the approach plate to do this. The approaches CAN be completed on F$2002, but the fixes for the particular approach must be programmed into the flight plan, before, the flight begins. This isn't very realistic, and it means that you have to know in advance, what runway you will be using at your destination. If you want an example of an RNAV approach plate, go to
