without ILS and for thin runways... i was wondering about diferent procedures just about a 100meters away from the point of landing how do you center or alling your  boeing747 or 777 to the runway
I don't know if it is me but everytime im in final (i always set wind of 8knut as default and hard mode)for some reason when i think i'm going straight to runway at the last moment these aircrafts seems to get of the vector(i know its the 8n of wind seted) i apply the rudder pedal to contrarest the detour and its worse,the best way i found was to use the ailerons and a very little push(sometimes) of rudder i make straight,beautiful and centered landings,practicly  just aileron.My question is in real life is correct  to use only aileron on final,and even with strong winds,i dont think is correct seeing a boeing747 making those bendings near the runway,Please I would like to Know
some information and opinion about this thing and how bad are my landing procedures ???

You can use the ailerons a little to crab over to get to the center of the runway, but if your real close to landing and you think you might crash doing this your best bet is to go around.

perfect exampleof what not to do

Well, when conducting an approach in crosswinds, there are 2 techniques which are good to know when landing heavy jets.

The crab crosswind technique

The objective is to maintain wings level thorughout the approach, touchdown and landing roll
On final approach a crab angle is established with wings level to hold the aircraft on the desired course. Application of downwind rudder is started prior to touchdown to eliminate the crab and align the aircraft with the runway centreline.

As rudder is applied, the upwind wing will sweep forward, developing roll. Hold the wings level by application of lateral control into the wind. Touchdown is made with cross control   
Note: On very slippery runways, it is wise to maintain the crab angle until you touchdown, this will reduce drift toward downwind side of the runway.

There is also the sideslip technique

The sideslip technique aligns the aircraft with the extended runway centreline. The initial phase of the approach is flown in the crab config to correct the winddrift. Prior to the flare, the AIRCRAFT centreline is aligned on - or parallel to the RUNWAY centreline. Downwind rudder is used to align the longitudinal axis to the desired track as aileron is applied into the wind to prevent drift.  A sideslip is established - opposite rudder and low wing into the wind to hold desired course.

You touchdown with the upwind wheels first, shortly followed by the upwind wheels.

In real life I always liked the slip myself but in ACOF many airplanes just don't do a good job of slipping. Only found a few that you can do a true slip in. One I think is the Super Decathlon and I've found some tweaked files for the Maule and Husky.
