The `flight_performance.cfg` is an *optional* file for aircraft SimObjects, but is not used by any other type of SimObject. This file is used to check the performance characteristics of an aircraft for use with the flight model and for correctly configuring **EFB** flight plans and other (user created) applications. Below you can find information on the different sections used in the `flight_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) and is currently mainly used by the {{< glossterm >}}efb{{< /glossterm >}} to generate flight plans within the simulation (the `[PERFORMANCE_DATA]` section is the exception, as this is *not* used by the EFB, but *is* used by the simulation for ATC, flightplan, and career missions).

 

This file is initially created using the **Debug Aircraft Flight Performance** window, and in this window you can create various *configurations*. In the generated file, the data for each configuration will be contained in the corresponding numbered section, and there will also be a *common* section. For example, if you have two configurations, you will have a `[AIRCRAFT_CONFIGURATION.0]` which is the common section, then you will have `[AIRCRAFT_CONFIGURATION.0]` (configuration 1) and `[AIRCRAFT_CONFIGURATION.1]` (configuration 2). This debug window is documented here:

-   [Debug Aircraft Flight Performance](../../devmode/editors/simobject-editor/debug_info/debug-aircraft-flight_performance.cfg/)

 

To aid with setting up this file, you can find a page of recommendations and explanations from the following link:

-   [flight\_performance.cfg - Setup](flight_performance.cfg/flight_performance.cfg/)

 

 

### [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.

### [PERFORMANCE_DATA]

This section is used to setup some specific performance value which will be used for *simulation* flightplan calculations - but *not* the EFB flightplans, unlike the other sections on this page - and ATC, as well as some career constraints (see [Mission Solving Constraints](../careers/general-career-information/general-career-mode-requirements/#mission_solving) for more information). Much of this information can be found online using a resource like [Aircraft Performance Database](https://learningzone.eurocontrol.int/ilp/customs/ATCPFDB/default.aspx?).

### [AIRCRAFT_CONFIGURATION.*N*]

This section is intended for storing general aerodynamic characteristics of the aircraft depending on its configuration. This section is indexed, meaning its title must contain an index separated from the section name by a dot. The index must be in the range 0 to 99, there must be at least one such section in the file - ie: `[AIRCRAFT_CONFIGURATION.0]` is mandatory - and indices must be consecutive.

 

The set of parameters that describe the aircraft configuration (landing gear, flaps, slats, spoilers) are *adaptive*, and their composition and values must correspond to the aircraft design specified in the file `flight_model.cfg`. If a discrepancy is detected when reading this section, then it may be processed as an error.

 

It should be noted that the [Debug Aircraft Flight Performance Tool](../../devmode/editors/simobject-editor/debug_info/debug-aircraft-flight_performance.cfg/) can be used to exports valid data for this section, depending on the selected aircraft configuration.

 

The parameters available to this section are as follows:

### [ENGINE_PERFORMANCE]

This section is intended for storing the aircraft engine characteristics, and as such it can be considered as *optional* given that aircraft like **gliders** do not have an engine. When filling in the data for this section there are few things to note:

-   Currently, this section **does not support more than one engine type** per aircraft.
-   Currently, the [Debug Aircraft Flight Performance Tool](../../devmode/editors/simobject-editor/debug_info/debug-aircraft-flight_performance.cfg/) can export valid data to this section **for turbine engines (jet / turbofan) only**.

 

As the simulation evolves this section will be improved to cover more engine types and configurations.

Note that there is no defined order for the densities to be added into this file as the values are referenced by their <em>index</em> in the list.

### [TAKEOFF_PERFORMANCE]

This section contains tables of data related to the performance when the aircraft is **taking off**. The performance data in this section can be calculated using two different methods:

-   Using the completed distance tables
-   Or using V-tables ({{< glossterm >}}v1{{< /glossterm >}}, {{< glossterm >}}vr{{< /glossterm >}}, {{< glossterm >}}v2{{< /glossterm >}}) to calculate distance (for more information on these calculations please see here: [Notes On V1, Vr, V2 Computations](flight_performance.cfg/flight-performance-info/#note_v1_vr_v2))

The distance table parameters that specify **takeoff ground roll distance** and **takeoff total distance** have *priority* in determining these distances for the {{< glossterm >}}efb{{< /glossterm >}}. If either (or both) of these tables are missing from this section, then the takeoff distances in the EFB will be calculated based on the V-table parameters, using aerodynamic data for the aircraft in the requested `[AIRCRAFT_CONFIGURATION.N]` and the available maximum thrust of the engines defined in the `[ENGINE_PERFORMANCE]` section. These calculations are performed on the basis of the physical laws of flight dynamics, which describe the acceleration of an aircraft to takeoff speed and its climb to the standard obstacle height (50 feet) under the physical forces acting on the aircraft (ie: weight, lift, drag, thrust, wheel friction). For more information on the takeoff distance calculations, please see here:

-   [Notes On Takeoff Distances](flight_performance.cfg/flight-performance-info/#note_takeoff)

`descent_econ_Mach_table_by_cost_index_and_TOD_weight_and_TOD_ISA_dev_and_TOD_altitude`

This table gives the descent econ (minimum cost speed) {{< glossterm >}}mach{{< /glossterm >}} number depending on 4 arguments:

1.  Cost index (integer)
2.  {{< glossterm >}}tod{{< /glossterm >}} Aircraft weight ({{< glossterm >}}lbs{{< /glossterm >}})
3.  {{< glossterm >}}tod{{< /glossterm >}} {{< glossterm >}}oat{{< /glossterm >}} deviation from {{< glossterm >}}isa{{< /glossterm >}} (°C)
4.  {{< glossterm >}}tod{{< /glossterm >}} Cruise pressure altitude ({{< glossterm >}}ft{{< /glossterm >}})

The table is formatted as follows:

``` cpp
