I got quite a bit of cross country time with instrument students doing navigational tracking and instrument approaches, especially in the faster airplanes. One way that I have been able to do that is by discussing their future aviation plans with them. If they are planning to become a professional pilot, they will need 500 hours of cross country time also. They can begin to build this time with you. Also, you need 500 cross country for both the ATP and for Part 135 IFR.
