# How to operate GCS

In this section you will get familiar with GCS application, its interface and possibilities it offers.

{% hint style="warning" %}
You might not see all features described in this section when you turn on your GCS. Some features are available only when you are connected to the UAV.
{% endhint %}

## GCS interface

Following subsections describe most important windows that you as user will use. Following table describes main interfaces, that you can use:

<table><thead><tr><th width="203">Interface name</th><th>Description</th></tr></thead><tbody><tr><td><strong>Fly view</strong></td><td>Command and monitor your vehicle while flying.</td></tr><tr><td><strong>Plan view</strong></td><td>Plan autonomous missions.</td></tr><tr><td><strong>Vehicle Setup</strong></td><td>An overview of all the important setup options for your vehicle.</td></tr><tr><td><strong>Analyze Tools</strong></td><td>Multiple analyze tools (for advanced users)</td></tr><tr><td><strong>Application Settings</strong></td><td>General GCS app settings</td></tr></tbody></table>

### Fly View

{% hint style="info" %}
After turning on GCS, Fly view is your first screen you encounter.
{% endhint %}

The Fly View is used to command and monitor the vehicle when flying. Typically it is used for following:

* Run an automated pre-flight checklist.
* Arm the vehicle (or check why it won’t arm).
* Control missions: start, continue, pause, and resume.
* Guide the vehicle to arm/disarm/emergency stop, takeoff/land, change altitude, go to or orbit a particular location, and return/RTL.
* Switch between a map view and a video view (if available)
* Display video, mission, telemetry, and other information for the current vehicle, and also switch between connected vehicles.
