Default value is 0 (false).

This can be set to 1 (true) to force the aircraft to use the legacy flight model, regardless of what the user may have selected in the Microsoft Flight Simulator options.

Default value is 0 (false).

This is only applicable to those aircraft that are using the legacy Flight Model. It was discovered that there was an issue with the acceleration integration calculations for the legacy flight model, and so this parameter exists to fix that. When set to 1 (true) the calculations will be correct, which may affect the handling of aircraft that have been calibrated using the "broken" flight model. When set to 0, the flight model will be the original one without the fix.

Default value is 0 (false).

In the modern flight model, this will set a target aerodynamic resistance value that the flight model will try to reach by adding more rotation resistance to each surface. As this system can only add more resistance, there will be a minimum native aerodynamic resistance below which the system can't go. By setting a low target, such as 0.1, the target is usually below the native aerodynamic rotation resistance which means that this parameter will have no effect. To add more aerodynamic resistance, use larger values.

As this system can only add more resistance, there will be a minimum native aerodynamic resistance below which the system can't go. By setting a low target, such as 0.1, the target is usually below the native aerodynamic rotation resistance which means that this parameter will have no effect.

Default value is 1.

This scalar can be used to modify how the actual aerodynamic surfaces are being flexed by the wingflex force. Set to 1, it should approximately do the correct wingflex, but it will depend on the aircraft wing stiffness.

Default value is 0.

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 movable 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.

This parameter allows you to define how much a non-movable 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.

Scalar that allows you to scale the lift contribution of a specific flap system. This is necessary to compensate for the scale by the deflection angle in radians, in order to reach 100%, ie: the computed lift coefficient is multiplied by the surface deflection, so you need to compensate for this deflection if it's inferior to 1 radian to reach 100% of your lift coefficient.
The flap lift formula is the following:

total_flap_lift = lift_coef_flaps * (system1.lift_scalar * system1.deflectionangleradians + system2.lift_scalar * system 2.deflectionangleradians...)

Default value is 1.

Scalar that allows you to scale the drag contribution of a specific flap system. It is necessary to compensate for the scale by the deflection angle in radians, in order to reach 100%, ie: the computed drag coefficient is multiplied by the surface deflection, so you need to compensate for this deflection if it's inferior to 1 radian to reach 100% of your drag coefficient.
The flap drag formula is the following:

total_flap_drag = drag_coef_flaps * (system1.drag_scalar * system1.deflectionangleradians + system2.drag_scalar * system 2.deflectionangleradians...)

Default value is 1.

The percentage of total pitch due to flap deflection that this flap set is responsible for at full deflection.

This is a legacy FSX parameter not used in the modern flight model. In the modern flight model, the pitch generated by flaps will depend on the lift added and the longitudinal position of the wings. The parameters of each flap level allow to move the wing longitudinally for each flap level to adjust the amount of pitch.

Default value is 1.

Specifies an altitude (in ft) above which the flaps cannot be extended.

Default is -1, which disables the feature.

This is a flap stage description, and you can have multiple definitions (starting at flaps-position.0) for each [FLAPS.N] section. The table of values takes the following 7 values in the given order:

• flap position - sets the flaps angular position for the stage, in degrees.
• airspeed limit - sets the airspeed limit for the stage, in Knots.
• drag scalar - sets a scalar to add or remove drag for the stage.
• lift scalar - sets a scalar to add or remove lift for the stage.
• area scalar - sets a scalar to add or remove area to the flap for the stage.
• add camber - sets an increase in the flap camber, raising the maximum lift coefficient or the upper limit to the lift a wing can generate. The value here is expressed in radians.
• add aft feet - sets the center of lift for the flaps stage, where a positive value will move the center of lift forward (generating more pitch up) and a negative value will move it back (generating more pitch down).
• add incidence - a scalar that lets you define how much of the additional lift is applied at 0° AoA. So, when set to 1 (100%), the additional lift is added constantly on the whole AoA range. When set to 0.5 (the default value), only 50% of the additional lift will be added at 0° of AoA and 100% at the stall AoA. The values in between depend on the normalization process.
  0.5 (50%) is the minimal value and you can go beyond 1.0, if required.

flaps-position-speed-factor.0 = 0:1, 150:1, 240:0 ;

Here, between 0 and 150 you get the full flaps position, but above 150 it starts getting reduced linearly until 240 at which point it's 0.

There can be multiple entries for this parameter, one for each flaps position, with i starting at 0 and up to number of positions - 1.

This parameter sets the override rules for flaps at the given position when above a certain speed. There can be multiple entries for this parameter, one for each flaps position, with i starting at 0 and up to number of positions - 1. The parameter requires the following two values, separated by a comma:

• the flaps position to use as the override
• the speed (in Knots) above which the given flaps position is used instead of the current one.
