The systems panel holds the switches you use before and after a flight. Open it with the **Systems** tile on the right of the cockpit screen. ![The systems panel](https://ifkits.com/wiki/img/systems-panel.png) | Section | Switches | | --- | --- | | **Misc** | Auto Start, Flight Plan, Auto Brakes | | **Interface** | Head-Up Display, Flight Path Vector, Flight Data (Infinite Flight's on-screen overlays) | | **Electrical** | Main Battery, Auxiliary Power (APU), External Power | | **Lights** | Navigation, Strobe, Landing, Beacon and Panel lights | | **Passengers** | Seat Belt Sign, No Smoking Sign | | **Engines** | Each engine on or off, Fuel Dump | | **Actions** | Captain Window, Copilot Window | Switches the current aircraft does not have are hidden automatically, so the panel looks different from one aircraft to the next. ## Starting the engines The quickest way is **Auto Start**: SkyYoke asks Infinite Flight to start every engine in order. To start engines one at a time, use the **Engine** switches. A typical cold-and-dark start: Main Battery on, External Power or APU on, Beacon Light on, then Auto Start. > **Do it by voice** Say "APU on, beacon on" with the [AI Voice Commander](https://ifkits.com/wiki/ai-voice-commander/) [Pro].
