Every time I fly using the fmc with the default 737, there’s always a constant roll to the left that doesn’t affect the aircraft at cruising alt, but gets really annoying at lower speeds, especially on approach, because the roll affects the positioning of the aircraft on the glide slope. I have tried raising and lowering the spoilers to no avail, and I haven’t found anything in the failures category yet that would cause this to happen. If anyone could please help me figure out what is causing this so I can fix it, that would be greatly appreciated.
