# Introduction

### Installation & Requirements

The Super27 Expansion is not a standalone product and **requires** the **727-200** Freighter or Passenger version **to be installed**.

{% hint style="warning" %}
Always keep the base packages updated to avoid unexpected behavior of the Super27.
{% endhint %}

If both the Freighter and Passenger versions are installed, the Super27 Expansion will be available for use with both.

### Aircraft Selection

In the aircraft selection menu, the Super27 packages appear as "727-200RE" for the Freighter and "727-200REP" for the Passenger version.

{% hint style="info" %}
Due to a technical limitation, both entries will always be visible, even if you have only one of the base packages installed. If you select a Super27 variant without the corresponding base installation, you’ll quickly see what happens – feel free to give it a try.
{% endhint %}
