I don't know where you did your IREX but suggest that your research and information given to you before choosing your school was misleading. The terms you are using are making me think that you didn't have very good instruction. I would have expected a newly minted IFR pilot who had just completed an IPC to be using terms like 3D and 2D and by the way an NDB approach is no longer required. You have every right to be very upset with your IPC provider especially if they don,t have an aircraft that is equipped to legally do GPS RNAV approach with a WAAS GPS.
