The Aircraft.cfg file represents the highest level of organization within an aircraft container. This file specifies the aircraft that are included in the aircraft container, as well as what the attributes (name, color, sound, panels, gauges, and so on) are for each aircraft and where to find the files that specify those attributes. The following example shows the contents of an Aircraft.cfg file.
Note: If a parameter isn't explicitly set, it automatically refers to the default directory. If you want multiple aircraft, texture, sound, panel, and model directories, use the directory naming convention directoryname.extension. To refer to the directory, just specify extension for the parameter.

You can edit the parameters in the [forcefeedback]
section of an Aircraft.cfg file to adjust the forces generated by
Flight Simulator so that different aircraft can have different force
effects, a different "feel" at the stick.
Note: The values and usage of the force feedback parameters are strongly tied to the ForceFeedBack feature of the DirectInput API (DirectX, version 5.0). It's strongly recommended that you refer to the DirectX, version 5.0 SDK to help you understand the use and effects of many of these parameters. You can download the DirectX, version 5.0 SDK from http://www.microsoft.com/directx.
The following table includes the data type and range for each

The following table describes the parameters included in the [forcefeedback]
section of the Aircraft.cfg file.
|
Parameters |
Description |
|
stick_shaker_magnitude, |
|
|
stick_shaker_direction, |
|
|
stick_shaker_period |
Define the behavior of the Stick Shaker force-feedback (FFB) effect: magnitude sets the amplitude of the force, direction specifies the angular direction of the force, and period sets the time period of the force's cycle. |
|
gear_bump_nose_magnitude, |
|
|
gear_bump_nose_direction, |
|
|
gear_bump_nose_duration |
Define the FFB behavior when the aircraft's nose gear is raised or lowered (cycled). Simulates the force felt through the aircraft's control stick/yoke, primarily as a result of forces felt through the aircraft's airframe and secondary forces resulting from the drag of the gear when it's exposed to the air moving around the aircraft. In fixed-gear aircraft, this FFB effect won't be felt because, by definition, the landing gear doesn't move. The magnitude, direction, and duration parameters are very similar to the stick shaker parameters described earlier in this table. |
|
gear_bump_left_magnitude |
|
|
gear_bump_left_direction, |
|
|
gear_bump_left_duration |
Identical to the gear_bump_nose parameters, described in the preceding entry, except that the force is triggered when the left landing gear is cycled. Different aircraft have different gear geometries that result in each of the gear mechanisms starting and ending its cycle at a different time. The timing deltas are brief, typically less than a second between the time that each gear starts and ends its cycle. |
|
gear_bump_right_magnitude, |
|
|
gear_bump_right_direction, |
|
|
gear_bump_right_duration |
Identical to the gear_bump_nose parameters, described earlier in this table, except that the force is triggered when the right landing gear is cycled. |
|
The following parameters are divided into two subgroups: |
|
|
ground_bumps_magnitude1, |
|
|
ground_bumps_angle1, |
|
|
ground_bumps_intercept1, |
|
|
ground_bumps_slope1 |
|
|
and |
|
|
ground_bumps_magnitude2, |
|
|
ground_bumps_angle2, |
|
|
ground_bumps_intercept2, |
|
|
ground_bumps_slope2 |
Each of the parameters in the subgroups defines the behavior of a distinct force. The combination of the two forces (1 and 2) together, define a composite force behavior that simulates the forces felt through an aircraft's ground steering controls. The two forces are both sinusoidal periodic forces. The frequency of each of these forces is determined by the following linear equation: frequency = (ground_bumps_slope? * aircraft_ground_speed) + ground_bumps_intercept? The ground_bumps_magnitude parameters set the magnitude of the force. The ground_bumps_angle parameters set the direction from which the force is felt. The crash_ parameters are divided into 2 subgroups: crash_magnitude1, crash_direction1 and crash_magnitude2, crash_direction2, crash_period2, crash_duration2 When a plane crashes two different forces are generated. The first force is a constant force that lasts for 0.5 seconds. After 0.5 seconds, it stops and the second force starts. The second force is a periodic square wave force; its amplitude declines linearly to 0. |
|
crash_magnitude1 |
Sets the magnitude of the first force. |
|
crash_direction1 |
Sets the direction from which first force is felt. |
|
crash_magnitude2 |
Sets the initial magnitude of the second force. |
|
crash_direction2 |
Sets the direction from which the second force is felt. |
|
crash_period2 |
Determines the frequency (frequency = 1/period) of the second crash force. |
|
crash_duration2 |
Sets the amount of time that the second crash force is felt. |
