On trying out the new psuedo-ILS function, I found it consistently putting me into a field some distance to the side of the runway. I've now discovered that the original published co-ordinates are incorrect, though near enough for VFR purposes.I have precise GPS co-ordinates for both thresholds. Is there a way to move the charted position of the runway to the correct position using this data? (The runway alignment is slightly out, but not enough to warrant a number change).
