### **Before Starting**

1. Download the latest version of the Elios 1 avionic firmware
2. [Update Cockpit](/aircraft/elios-1/elios-1-cockpit-app.md) to the latest Version on the Tablet of the controller

### **Automatic Installation**

All Elios 1 systems running Avionics Firmware 1.1 or higher and Cockpit 1.1 or higher are capable of automatically upgrading, provided that the tablet has access to the internet. Upon starting the Cockpit app, a notification will appear to inform you that a new version is available. Follow the instructions to install the new version of the App. The avionics firmware of the drone can be upgraded "over the air" if the ground controller and drone are also connected and powered on.

{% hint style="info" %}
Make sure that there are no old firmware files left on the SD card, as in this case the "Over The Air" upgrade will not work correctly.
{% endhint %}

If you do not wish to connect your tablet to the internet, or if you are running firmware prior to V1.1, then the application and firmware can be upgraded offline through the process described below:
