This questions has been killing me, what is the name of the leading
edge flaps that you find on airliners for example. Ive heard the name
slats, but I know there is another name for it.

In general, they can be called "leading edge flaps."

Some of them are specific designs, such as the "Kreuger flaps" on 727s and the
inboard segment of 747s. Others, such as the outboard segments of the 747s,
look like, and perform the same function when extended, as the "leading edge
slats" on the F-86, A-4, and A-6. However, because of the manner in which they
are stowed and deployed on the 747, they are still called "leading edge flaps."
