# On MAVLink Start

## Overview

![The On MAVLink Start Node.](/files/Aj6CfXx6g4GEUoIq3WCa)

**On MAVLink Start** is an **Event Listener Node** notifying that the **MAVLink** connection was successfully established, therefore enabling the user to trigger a **Logic Branch** on said connection.

**MAVLink Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **On MAVLink Start** will not show up in the [**Toolbox**](/incari-studio/2024.1/toolbox/overview.md). Please refer to the [**Plugins Editor**](/incari-studio/2024.1/modules/plugins.md) to find out more information.

[**Scope**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2024.1/toolbox/communication/overview.md#scopes): **Project**, **Scene**.
