leading edge flaps

FWIW the L1011 had a neat mode of spoiler operation - with the
trailing edge flaps in land (33 degrees) position the wing spoilers
were positioned up 8 degrees. Slight movement of the yoke fore or aft
from the trimmed position raised or lowered the spoilers effecting a
useful change in lift with minimal change in AOA. Made it very easy to
stay on a glideslope or maintain a set rate of descent.

Also done in the Navy F-14 and S-3, with minor variations.

Also done in many gliders, though manually, as a matter of course in the landing
pattern...
