Could anyone confirm whether PVD systems give rwy centreline guidance during landing rollout as well as during t/o roll.

Thanks

Yes they do.
(e.g. L1011 and B777)

They are a backup cue on low vis takeoffs and rollout monitoring on a autoland app.

777 uses PVD for take-off guidance and for landing with auto-pilot off only that's good gen from MM

L1011 PVD required for cat3b landing.

Thank you all very much for your responses. They've helped me clear up a couple of questions.
