Thanks, CJ.
An independent source confirmed a few days ago that the ADP's run on a CF6-powered 744 even when selecting Flap 1 (so I suspect that the logic is fairly dumb, not actually looking at the requirement for hydraulics). This may even be the case when the flaps have switched to Primary Electric ops during a hydraulic flap drive failure.
Cheers.
