Compared to FSX you don't have vLSO which is quite handy and teaches the pilot how to get the approach right but DCS has yet to have a meatball so the approach is more by seat of the pants stuff. It does have though ILS and something else lol autopilot which in the SU33s case = Auto land.
So 1 goto instant action SU33 recovery
2 g gear, Shift F flaps
3 Alt G for Hook
4 push 1 twice to get ILS mode
5 push A and there you have it, it'll land itself. For the noob like me take note of the height and AoA on approach and distance and then at some point have a crack at landing. You can hit A to turn auto pilot off and do the landing bit yourself for practice.


BTW I discovered autoland quite by mistake, one day I happened to bother using autopilot and noticed the plane start the approach by itself which is very handy. To late for all those Airwolves Squadron missions where I crashed the SU33 lol.
