CROSSWIND EFFECTS ON LANDING AND TAKE OFF
-
Since MSFS sim update 10 I have been having problems taking off and landing in crosswinds, with even moderate 10-12 kt crosswind components causing the aircraft to lean heavily into wind and large aileron and rudder inputs being required to keep the aircraft on the runway, let alone the centreline.
The following thread on the MSFS forum leads me to the conclusion that MSFS have released new wheel friction values into the aircraft settings in order to allow aircraft developers to tune the crosswind effects.

So as these are apparently new settings, presumably they are not yet available within the 146 config files. I wonder whether anyone has tried to add these settings, and if so what success they have had.
Obviously I would hope that Just Flight are fine tuning the next aircraft update in order to reduce the current extreme crosswind effects.

@clevatreva +1 on this. I've noticed since the weather update, the 146 is pretty difficult to control on the ground, and in the early stages of flight.

Microsoft has recently added four additional adjustments to the SDK which aircraft designers can use to tweak the effects of crosswinds during the ground roll of an aircraft. See their Forum for details:

The adjustments are included in the flight model cfg file of each aircraft. For example:
\Community\justflight-aircraft-146\SimObjects\Airplanes\JF_146_200 \ flight.model.cfg. FLIGHT TUNING SECTION
**ground_crosswind_effect_zero_speed=
This parameter represents the world speed (in ft per second) at which 0% of the crosswind effect is applied to the aircraft. This parameter will work in two different ways:
With the ground rudder assistance enabled, at the given speed and below, the lateral (x) component of the wind is set to zero.
With the ground rudder assistance disabled, crosswind is completely cancelled out below ground_crosswind_effect_zero_speed ft per seconds of IAS, and it is gradually blended in up to 100% at ground_crosswind_effect_max_speed ft per seconds of IAS.
Note that this value can be set to -1000 to have a 100% realistic simulation where the crosswind is never cancelled out.
Default value is 5.ground_crosswind_effect_max_speed=

Default value is 80.ground_high_speed_steeringwheel_static_friction_scalar =
At high speeds, tires are rolling and - depending on their shape and width and how much they are inflated - they will more or less resist rotation or sideways motion. This parameter allows you to define how much a moveable wheel resists static friction which goes sideways or resists rotation around the vertical axis. Essentially, it allows you to control how much the aircraft will move into the crosswind when rolling at higher speeds, and reducing the scalar will reduce the friction, so the aircraft is more likely to slide. Note that only the lateral forces are impacted by this value, so rolling friction and braking when your aircraft is rolling straight will not be influenced.
Default value is 1.ground_high_speed_otherwheel_static_friction_scalar =

Default value is 1.**Presumably Just Flight will be amending the flight.model cfg at the next update.
As an interim measure I have added the following to my flight.model.cfg file. FLIGHT TUNING SECTION
ground_crosswind_effect_zero_speed=5
ground_crosswind_effect_max_speed=260
ground_high_speed_steeringwheel_static_friction_scalar = 1
ground_high_speed_otherwheel_static_friction_scalar = 1Effectively, if my reading of the SDK is correct, this reduces the crosswind effect, while the aircraft is on the ground, from nil at 5ft per second, 3kts, to full at 240 ft per second or 143kts. This may seem rather extreme, but my experience is that the Microsoft crosswind effect is greatly exaggerated compared to real life. As far as the static friction settings, I have copied the settings that others are using for different aircraft.
This has helped me, but obviously when Just Flight publish the next upgrade the settings will be reset to whatever they deem correct.
