Indeed it does. The 747 has 2 inboard panels and 4 outboard on each
wing. For in flight speedbrake purposes, all will raise except the
outer 2 panels on the outboard set (if the outer ones deployed,
excessive pitch up can result, as they are located significantly
aft of CG). On the ground, in a spoiler capacity, all panels raise.
And, the spoilers will work with ailerons, I believe, at low speeds
to assist in roll capability. Hope this helps.
