# target_performance.cfg The `target_performance.cfg` is an *optional* file for aircraft, and is never required for any other kind of SimObject. It is used to define the performance characteristics of the aircraft. Below you can find information on the different sections used in the `target_performance.cfg` file as well as what parameters and values are expected within them. However it should be noted that that the information contained in this file *has no influence on the aircraft flight behavior*, and is instead used to compare computed performance versus expected performance (which can be found in the {{< glossterm >}}poh{{< /glossterm >}} or from industrial or academic data).   All parameters in this file can take one *or* two values where: - The first value is the target value. - The second value is optional and is a {{< glossterm >}}percent_over_100{{< /glossterm >}} providing the error tolerance when comparing this target value and the value computed in game with the flight model.     ### [Version] The `[Version]` section provides version information for the configuration file. In Microsoft Flight Simulator 2024, major versions should *always* be at least equal to 1.   Note that this section information is **mandatory** and should always be included.   {{< table-wrapper >}} | Parameter | Description | Type | Required | |-----------|---------------------------------------------------------------|---------|:--------:| | `major` | Major CFG file version number, values must be greater than 0. | Integer | Yes | | `minor` | Minor CFG file version number, values must be greater than 0. | Integer | Yes | {{< /table-wrapper >}}     ### [TARGET_PERFORMANCE] This section provides general information for the aircraft performance.
