In descent phases, clean config, VNAV PATH changes to SPEED, if you select Speed Intervention . With flaps down, in a VNAV approach, it will stay on VNAV path.
But that still has nothing to do with my experience, that high on a descent leg, the PATH would lead me to an overspeed, if I did not intervene. Is it because the AP does a bad job? Or was it just looking like that? I obviously prevented it from happening.
