    Marc is exactly correct. No TSO; no play with the certified/TSOd airplanes. The rules are not there for X-plane pilots; they are there to protect the ones playing legally in the NAS.

    Actually, not fully correct. Regs say the GPS must meet same TSO as cert; not that user must have said testing data from manufacturer. FAA now uses performance based criteria to demonstrate compliance, so one could make a reasonable effort to prove it meets the same ELOS. I was wondering just how in depth this would be for a good avionics shop to reasonably perform. When I was a DER flight test pilot for big planes, much of the art of the certification plan was to do just that, find quickest (and cheapest) method to demonstrate compliance.

    Additionally, any part 91 aircraft can file & fly IFR in VMC for training and checkride purposes legally.... without any IFR "certified" equipment. So even though my experimental C172 equipment (EFIS and GPS) is not "certified" as long as I stay VMC for training purposes.

    Just wondering if anyone look more in depth about into the TSO angle
