# Downloading & Installing ACARS

---

In order for our customized, proprietary *Flight Data System* to function properly, it must be connected to your Sim so the data your flight generates can be transmitted to it. That transmission of data is facilitated by ACARS software.

<p class="callout info">*The term ACARS is intended to cover all Fight Tracking Software.*</p>
