The other day I was flying a mission and decided to let the autopilot land the plane. I noticed that the flaps didnt deploy, but that some slats on the front of the wing did, any idea what these are, what they do and how do I use them??

Slats on the front of the wing are automatically controled. I think it has to do with the angle of attack but they extend to help give you a bit more lift and make a turn better.

They are also on the Bf 109.

Wing Slats are a high lift device on the leading edge of the wing. In this case they are sprung open mechanically and when you reach a certain airspeed they are pushed back against the leading edge. Once you start to slow down or hit a high AOA they move forward again.

In a modern airplane they are controlled by the flight computer and or the pilot.

The idea behind them is they keep the airflowing properly over your ailerons during slow speed or better yet high angles of attack (AOA). This allows you to maintain aileron control (ROLL) during those periods.

Aircraft engineers tended to try and make the wing stall from the inside to the outside first for the very same reason. In this case they went with slats.

These leading edge slats are mechanical but they are not linked to any control - at least in the Me109's

And on the pilot check list you must make sure that you can push them in and pull them out fully with just one finger.. extremely light touch and there must be no binding - they must glide smoothly.
