Slats are typically UN-powered devices on the leading edge that extend
simply by the reduced dynamic pressure against them as airspeed slows.
Example would be the leading edge extensions of the F-86 and F-100.

I wouldn't agree with "typically." Aero slats also extend when a certain
AOA is achieved ... the A-4 slats would extend at approximately 12 units
AOA
(IIRC) and bringing them out symmetrically at higher airspeeds was not a
sure thing.

The Blues bolted 'um shut. Can you imagine what would happen in a tight
diamond with an A4 if a wing position got an asymmetrical slat extension
with roll induced....say in a barrel roll? Not a pretty thought!! :-))
