# AirSim Simulation

:::warning
This simulator is [community supported and maintained](../simulation/community_supported_simulators.md).
It may or may not work with current versions of PX4.

See [Toolchain Installation](../dev_setup/dev_env.md) for information about the environments and tools supported by the core development team.
:::

[AirSim](https://microsoft.github.io/AirSim/) is a open-source, cross platform simulator for drones, built on _Unreal Engine_.
It provides physically and visually realistic simulations of Pixhawk/PX4 using either Hardware-In-The-Loop (HITL) or Software-In-The-Loop (SITL).

## PX4 Setup

[PX4 Setup for AirSim](https://microsoft.github.io/AirSim/px4_setup/) describes how to use PX4 with AirSim using both [SITL](https://microsoft.github.io/AirSim/px4_sitl/) and [HITL](https://microsoft.github.io/AirSim/px4_setup/#setting-up-px4-hardware-in-loop).

:::info
WSL 2 is not a supported [PX4 Windows development environment](../dev_setup/dev_env_windows_cygwin.md), mainly because it is non-trivial to display simulator UIs running within WSL 2 in the normal Windows environment.
This limitation does not apply for AirSim because its UI is run natively in Windows.
