    The data agrees with my real world EFB, so it agrees with data used by real airlines.

    This is in China? In China, satellite imagery will usually not match with WGS84 coordinates, as the coordinates of satellite data is shifted in China. See https://en.wikipedia.org/wiki/Restrictions_on_geographic_data_in_China#GPS_shift_problem

    For chinese airports, you need to ignore the image and match the WGS84 data. If you move the runway to match the image, the ILS approach will lead to airplanes landing in the grass, as the ILS data is also WGS84.

    I checked the MAPT point with the RNP approach and confirmed that the ESRI satellite image was fine.You can look at Mangshi airport(ICAO:ZPMS), the same problem.
