737NG Rudder Problem

[Orlaam 306]

I asked this a while back and no one responded. For some reason when I'm in the air with the NG (-600 to -900), I can't get any rudder authority unless I turn off the Yaw Damper. The rudder works fine on the ground for taxi, and I have no problems in any other aircraft with rudder input. My auto-coordination is most certainly off, and I have no other settings I can think of that would cause me to lose the ability to have some control in crosswinds. It makes dealing with x-winds on final a real problem.What could it be that it only works with the YD turned off when it should be left on?

Oh yeah. This seems to be a new problem, as I don't remember it doing this a few months back when I was flying the NG more often.

How about posting a screen shot of your overhead panel? Lately when I start up 737ng some electrical settings are wrong. I have not saved any flights etc. and still do not get the default when starting. Someone on here can probably tell from looking at a screen shot if there is a problem there.RegardsRick

<>I'm wondering what you're trying to do with rudder during approach, but can't help with the technical problem. During crosswind landing, the aircraft should be flown with a crab angle on final to maintain a track coincident with the final course. The difference between your heading and the runway heading will depend on the magnitude of the crosswind component. The crab angle is held until just before flare, where the rudder is used to line up with the runway center line and then to prevent from being blown downwind the downwind wing is raised and a bank held in a cross-control (rudder and bank are opposite of each other). In other words, you kick rudder to line up and turn into the wind. Use right rudder to move the nose to the right and use opposite bank if the wind is blowing left to right. If done right, the upwind main gear will touch down before the downwind gear with the aircraft over the center of the runway and lined up with the runway. This manuever shouldn't be done until just at flare because it is an uncoordinated manuever that increases sink rate, which is compensated for by the flare.I get many opportunites to execute this in Corpus Christi, our normal winds are about 20kts usually 30-deg to my preferred runway. However, I have found the manuever difficult to execute smoothly in a flight simulator because I'm missing the "seat of the pants" feel for slip/skid and sink. It's usually ends up being a touchdown in some kind of crab that's hard on real landing gear but FS doesn't care. Steering the rollout is the main challange.
