For those who have Rudder Authority problems - Solution...

[teropa]

Hi,Many times I wondered how people here could get enough of rudder authority during v1 cuts and crosswind landings with BOTH Yaw Dampers turned ON (which means that the "real" YD is on PLUS FS auto-coordination is ON as well, which is the Right YD in PIC767).I couldn't duplicate the effect, no matter how high I would setup the rudder_effectiveness -value in the aircraft.cfg.Today a friend in IRC suggested a solution, and while the real solution wasn't exactly the one he suggested, it was even more simple.To be able to affect the rudder_effectiveness of an aircraft, one MUST have the line{flight_tuning} (replace the {} with the other kind of parenthesis)in the aircraft.cfg BEFORE the rudder_effectiveness line! It will NOT work, if you simply add the rudder_effectiveness line somewhere in the cfg. The above line must be there for FS to process the non-standard, desired effectiveness (that in this case is vital for the rudder to be effective enough to provide authority WITH both YD's on). I tested this several times, and am 100% sure that for those who haven't been able to get the rudder to work properly, this is the "key".I also noticed that the suggested value of 24 might be a tad too less when faced with an "evil" crosswind situation or a V1 cut. I myself set it to 50, which provides more realistic rudder authority on the B757. regards,Terops. thanks to Sebastian Hyv

Hi Tero,When you state to replace the { } parenthesis with the other kind of parenthesis, which is the other type that you are referring to...Example: () or [] ?? or maybe it doesn't matter which one! Regards,jack

[Guest gremel]

I guess I didn't separate the parenthesis' very well. The other type of parenthesis would be ( ) ir [ ]....Regards again,jack

The rudder_effectiveness can be changed to anything you feel comfy with.

Jack,I meant the [] ones, just didn't know I could type them here.Mark,If there's no flight tuning section, the cut from your cfg will not work. The point of my message wasn't that rudder_effectiveness can be changed to anything, but that for it to work, there need be the magical header in it.Tero

[Guest Mark McG]

Tero,I forgot to cut the [] bit

[teropa]

Mark,Ok :). I found out about those other parameters you quoted as well, but I'm not sure I will add them to my config. Since all the rudder needs for to work is the "flight_tuning" inside [] and the rudder_effectiveness line.The original PIC cfg doesn't have those parameters in there. The POSKY merge adds those lines, not sure why, and is it relevant or not ?Tero

[Guest Mark McG]

Not sure if it is relevant or needed.Was introduced with the switch from FS2000 to FS2002, and MS wanting to include more stuff in the aircraft.cfg file, rather than the airfile - hence why I only changed the rudder effectivenss.Changing the other values screws with the airfile.Later

Ok I knew about the flight tuning section. But when I saw this thread I checked mine just to make sure everything is ok and found a few extra lines that have never been there before. Anybody have any idea where they came from? That wasn't there two months ago, I checked my backup *.cfg file (from two months ago).[flight_tuning]cruise_lift_scalar=1.0parasite_drag_scalar=1.0induced_drag_scalar=1.0elevator_effectiveness=1.0aileron_effectiveness=1.0rudder_effectiveness=25.0pitch_stability=1.0roll_stability=1.0yaw_stability=1.0elevator_trim_effectiveness=1.0aileron_trim_effectiveness=1.0rudder_trim_effectiveness=1.0[brakes]toe_brakes_scale=0.687521parking_brake=1[gear_warning_system]gear_warning_available=0pct_throttle_limit=0.099976flap_limit_power=37.242257flap_limit_idle=31.512679[hydraulic_system]electric_pumps=0engine_map=1,1,0,0normal_pressure=3000.000000[stall_warning]type=1[attitude_indicators]attitude_indicator.0=1[turn_indicators]turn_indicator.0=1,0

The new stuff might have come from the .air file. FS extracts some parameters out of the .air file and inserts them into the aircraft.cfg file.Lee Hetherington (KBED)

Hi Sebastion,I was about to post a message on the forum ref rudder authority and I saw your input on the subject!! Would you be able to advise on what control system ie joystick/control column, rudder, throttle quadrant etc for 767pic?RegardsDCox:-)

[Guest SIMMSLOT]

Hi Mark,I was just about to ask about rudder authority when up popped Sebastions message with everyones input! I just wondered what control system(joystick/rudder throttle quadrant)you use to practise the single engine stuff?RegardsDc :-)

[Guest Mark McG]

I have the following:CH Products Yoke USBCH Products Rudder Pedals Pro USBCurrently I use the levers on the yoke for throttle.

Mark,I remember the '24' value from way back but have always kept mine at '1' and just switched off both dampers.However I would like clarification over the RH damper. Can that be left off so auto-coord never gets implemented or does the aircarft realism setting overide the 767's damper position?IOW If I have auto-coord off in the realism settings will switching the RH damper on still switch auto-coord on?Thanks

[teropa]

Vulcan,Even if you have auto-coord OFF in the realism settings, the Right Yaw Damper will activate FS auto-coordination if left on. When you turn it off, you will have auto-coordination turned off as well.IF you have FS auto-coord set to ON in the realism settings, I'm not sure if turning off the R YD will turn it off though.I currently fly with both YDs on (ie. FS auto-coord on), AND have set my rudder-effectiveness value to 45. This value provides enough authority with even the auto-coord ON. Of course, during nasty crosswind takeoffs and landings I turn the R YD OFF to be able to cross the controls in landing, and provide upwind aileron during takeoff.Tero
