# Aircraft System Variables<no value>
The tables below indicate the properties for the [Simulation Variables](../../simulation-variables/) that can be used to get and set properties related to the various aircraft controls and systems. For information on the units listed for each variable, please see here: [Simulation Variable Units](../../simulation-variable-units/)

{{< callout context="note" title="NOTE" icon="outline/bulb" >}}

When Microsoft Flight Simulator 2024 is running in multiplayer mode, only a small number of variables are communicated between aircraft. Those variables that are available will say so in the description as being either for "All Aircraft" or for "Shared Cockpit".

You can find a complete index of all available SimVars here: [SimVar Index](../../simulation-variables/#simvar-index)

### Hydraulics

These SimVars are all related to the [Modular Hydraulics System](../../../../content-configuration/cfg-files/system/modular-hydraulics-system-information/). Most of them require the name of the component that they target. This name is given using the following format:

``` xml
[SimVar]:'[COMPONENT_NAME]'_n
```

For example:

``` xml
(A:HYDRAULIC ACTUATOR PCT INTEGRITY:'LandingGear'_n, Enum)
```

### Pneumatics

These SimVars are all related to the [Modular Pneumatics System](../../../../content-configuration/cfg-files/system/modular-pneumatics-system-information/). Most of them require the name of the component that they target. This name is given using the following format:

``` xml
[SimVar]:'[COMPONENT_NAME]'_n
```

For example:

``` xml
(A:PNEUMATICS AREA TARGET TEMPERATURE PCT:'Cabin_Area'_n, Enum)
```
