I hope that someome can help me. I am working on the Private Pilot Checkride and I have a problem with the plane banking to the left. I thought it was my yoke or the rudder being out of calibration but they are centered. I have noticed that my turn coordinator has a major angle to the left at times even on the runway. Why would the turn coordinator be showing a turn on the runway? I can't check on the loading of the plane because it is part of a lesson.Is there something I must modify to get the default Cessna to be centered for flying? Any help would be appreciated.

As for your overall turning problems, I'm not sure, but I can tell you the turn coordinator indicating a turn on the ground is normal.The TC indicates both bank and roll. On the ground, the centrifugal force of turning is acting on the gyro the same way an airborne turn would be, so the TC indicates a turn.

I'll confess I've never paid much attention to the behavior of the Turn Coordinator, AKA "needle & ball", in FS because most of the planes I fly don't even have one in the panel. However, the Real World turn coordinator indicates a bank only indirectly. The TC is designed to directly idicate yaw, or rotation about the vertical axis. So it correctly indicates a turn whenever the aircraft is yawing, which of course occurs in response to rudder inputs on the runway.The TC indicates bank only indirectly, I say, because it is only after introduction of a bank has resulted in the aircraft beginning to change heading that the needle will move off center. It is possible to bank the airplane in a slip and have the TC needle stay pretty well centered. Likewise, it is possible to make a nonbanked turn using rudder only, and have the TC show a turn. All of the preceding, witty and informative as it may be, doesn't solve your turning problem. I'm thinking, if you have (in the Aircraft Realism section) the torque, P-factor, & gyro sliders anywhere except all the way to the left, that could be the source of your problem. Many default airplanes in FS have (in the past, at least) responded to rudder inputs by rolling at least as much as yawing. If you have those sliders over to the right, the sim is giving you the classic single engine problem called "left-turning tendency", a combination of forces from the three effects whose sliders were mentioned above. It would not surprise me for a typical "badly-behaved-in-yaw" airplane to respond with a constant tendency to roll to the left. Another source of your turn could be aileron trim. "But the Cessna doesn't have aileron trim", you might object, and you'd be right. However, if the airplane you flew before switching to the Cessna had aileron trim and was off-centered for any reason such as fuel imbalance or single-engine flying in a multiengine airplane (or if you saved a flight in such an airplane and ticked the "make default" checkbox)...it will not have gotten centered in the switch, and in the Cessna, you lack the gauge to see the problem, as well as the knob to fix it. Switch to another aircraft such as the Baron which does have aileron trim, see what the gauge says, and take appropriate action.I've not flown the default FS9 Cessna 172, but I seem to recall that some versions of the real airplane have rudder trim. If the FS9 aircraft mimics this, and if the rudder trim has gotten offset to the left, you could see the same rolling problems described above. Check the gauge, if there is one. Otherwise, it is possible that the airplane you flew before the Cessna had rudder trim, and...(see above paragraph)Still having problems? It's got to be your stick. Switch to another multi, jet, or helo and see what happens. Also...I had a situation just last week where my digital stick showed as being calibrated in the Game Controllers applet, but was 'way off in the airplane. Calibrate it anyway and see what happens.Hope this helps,

Beachcomber, I think you may be confusing a turn indicator with a turn coordinator as far as indicating bank is concerned. A Turn and Slip Indicator will only display rate of turn, whereas a TC can show rate of bank. Therefore, a TC will display a change when only banked, whereas the turn indicator will not.Edit: I understand what you are saying about entering a slip, but that is introducing different forces.

Thank you to everyone who is offering advice. I will check my settings sliders when I get home. One thing I have noticed is that the turn coordinator shows bank even when I am not moving on the runway. Almost as if a big gust of wind has rotated the plane along the long fusalage axis. When I look at the red readings at the top of the screen it says that the wind is 340@00 which I believe is "out of 340 degrees at 0 knots". Hopefully changing the sliders will help with the problem. I am getting tired of failing the checkride because I am fighting the left turn tendency.Dreamflyer Out

Yes, the TC shouldn't be showing a turn on the ground if you are not turning. (unless you have gyro failures enabled and it tumbled) Anyhow, I also keep the left turning tendency sliders to the left, because it is over modeled unrealistically.

Both a turn coordinator and a turn and slip indicator would indicate a turn in the direction of the turn on the ground. The inclinometer (the ball) would also swing to the outside of the turn.You're misinterpreting what information the gauge gives you. It tells you nothing about your bank angle, it is simply an indicator of the rate at which you're turning. Both types of indicators detect the rate of yaw. The turn coordinator also can detect rate of roll as the gryo is canted at an angle. The turn and slip indicator only detects yaw.Since yawing is exactly what you do on the ground to maneuver around, it would be normal to see the indication even on the runway. Infact, it's part of our intrument cockpit check as we taxi to the runway for an IFR flight. We turn a few times on ground and note the diflection, which is ussually full scale because you turn much faster then the 3

BTW:turn cooredinator is useless in MSFS. Try performing a standard rate turn and you'll see what I mean...If you align one of the "little airplane" wings in, say, the default CESSNA or even on your best GA add-on, and start what was supposed to be a 3 degree per second turn, you'll notice that it'll take on about 1:40'' to complete a full 360!!! On other airplanes you can be presented with just the opposite - taking a lot more than 2' to perform...I have yet to know of an independant gauge for T & S.

I don't think anyone mentioned bank angle. And yes, the discussion about differences has obviously been about airborne operation, if that wasn't made clear.

Thank you to everyone who has helped with the left turn problem. After adjusting my realism settings to 65% and the sensitivity on my yoke, I feel comfortable with the way the plane flies. I was even able to pass the checkride on my second attempt last night. Thanks to all of the advice and explanations. Now it is time to start the instrument lessons.Dreamflyer Out. :-)
