They don't actually always come out all at once with a loud sound but it is also possible that they move slightly out and in in slow level flight. I didn't know this until I saw it in in-flight video of Black 6. So their operation does not rely only on AoA but also of speed.

right........they rely on negative pressure on the wing.......when the wing is about to stall for ANY reason, there's negative air presure there.......because it's not producing lift for what ever reason......but since the wing has to exceed the aircraft's critical angle of attack to stall, yes......AOA still does play a part. when you slow down in level flight, what do you do to maintain your alt? you lift the nose. the slower you go, the higher you pitch the nose.....untill critical AOA is reached, then ya stall. a stall can also happen at hi speed though as we all know, because AGAIN, when we try to turn inside that spit9, we're pulling the wing up to the critical AOA. remember....the plane doesn't know which way is up.....you can be banked 60 degrees, and pulling, and the plane can exceed its critical AOA to the oncomming wind. to the plane, the oncomming wind is obvioulsy from its front.assume 109 AOA in normal flight is 10 degrees(i don't know, just using a for instance) and its critical aoa is 17 degrees. now, you roll and pull into turn, smoothly and coordinated, you bring it around nicely never pulling the wing up past 13 degrees. but now ya get bounced...you pull hard, and the wing hits 17-18 degrees......now the air cannot flow properly over it, so it stops producing lift, creating the negative air pressure on the wing, and the slats drop, increasing the wing's camber, allowing it to produce some lift till you get back into normal flight.
if i'm wrong on this then someone please correct me?
now.....i'm gonna get flamed for this, aren't i?
