- Press the _Flight mode_ text (e.g. "Hold") to select a new mode.
Not every mode may be available.
- The text next to the **Q** icon indicates the flight readiness using text: "Not Ready", "Ready to Fly", "Flying", and status using colour: "green" (all good!), amber (a warning), red (serious problem).
Select the text when the background is amber or red to find out the cause of any preflight issues (QGC 4.2.0 and later).
You can also select the text to reach a button to arm/disarm/emergency-stop the vehicle.
- Enable the [preflight checklist](#preflight_checklist) (tool option disabled by default).
- **[Instrument Panel](#instrument_panel):** A multi-page widget that displays vehicle information including: telemetry, camera, video, system health, and vibration.
There are a number of other elements that are not displayed by default/are only displayed in certain conditions.
For example, the multi-vehicle selector is only displayed if you have multiple vehicles, and the preflight checklist tool button is only displayed if the appropriate setting is enabled.
The instrument panel is a multi-page widget that displays information about the current vehicle, including: telemetry, camera, video, system health, and vibration information.
You configure what information is display by selecting the edit/pencil icon.
The grid will then display "+" and "-" icons that you can use to add or remove rows and columns (and the pencil icon is replaced by a "lock" icon that you can use to save the settings).
Most of the settings that are displayed depend on the camera (they are defined in its [MAVLink Camera Definition File](https://mavlink.io/en/services/camera_def.html)).
When connected to camera that supports the [MAVLink Camera Protocol](https://mavlink.io/en/services/camera.html) you can additionally configure and use other camera services that it makes available.
For example, if your camera supports video mode you will be able to switch between still image capture and video mode, and start/stop recording.
::: info
Most of the settings that are displayed depend on the camera (they are defined in its [MAVLink Camera Definition File](https://mavlink.io/en/services/camera_def.html)).
> A few common settings at the end are hard-coded: Photo Mode (Single/Time Lapse), Photo Interval (if Time Lapse), Reset Camera Defaults (sends a reset command to the camera), Format (storage)
To view the checklist, first enable the tool by navigating to [Application Settings > General > Fly View](../settings_view/general.md) and selecting the **Use preflight checklist** checkbox.
The tool will then be added to the _Flight Tools_.
If the background is amber then it is ready to take off in the current mode, but may not be able to switch to other modes.
If the background is red and the text is "Not Ready" then you will not be able to arm in the current mode.
From QGC 4.2.0 (at time of writing, a daily build) you can find out the exact cause of the warning or error, and possible solutions, by pushing the status text.
This launches the preflight arming checks popup with a list of all preflight warnings.
The toggle on the right expands each error with additional information and possible solutions.
Once each issue is resolved it will disappear from the UI.
When all issues blocking arming have been removed you can use the arm button to display the arming confirmation slider, and arm the vehicle (or you can just take off - note that the vehicles will (by default) disarm automatically if you do not take off after a few seconds.
To arm the vehicle, select **Disarmed** in the _Fly Toolbar_ and then use the confirmation sider.
You can _continue_ mission from the _next_ waypoint when you're flying (the _Continue Mission_ confirmation slider is often displayed by default after you takeoff).
Continue and [Resume mission](#resume_mission) are different!
Continue is used to restart a mission that has been paused, or where you have taken off, so you've already missed a takeoff mission command.
Resume mission is used when you've used a RTL or landed midway through a mission (e.g. for a battery change) and then wish to continue the next mission item (i.e. it takes you to where you were up to in the mission, rather than continuing from your place in the mission).
_Resume Mission_ is used to resume a mission after performing an [RTL/Return](#rtl) or [Land](#land) from within a mission (in order, for example, to perform a battery change).
After landing you will be prompted with a _Flight Plan complete_ dialog, which gives you the option to remove the plan from the vehicle, leave it on the vehicle, or to resume the mission from the last waypoint that was traveled through.
A mission cannot simply resume from the last mission item that the vehicle executed, because there may be multiple items at the last waypoint that affect the next stage of the mission (e.g. speed commands or camera control commands).
Instead _QGroundControl_ rebuilds the mission, starting from the last mission item flown, and automatically prepending any relevant commands to the front of the mission.
When video streaming is enabled, _QGroundControl_ will display the video stream for the currently selected vehicle in the "video switcher window" at the bottom left of the map.
You can press the switcher anywhere to toggle _Video_ and _Map_ to foreground (in the image below, the video is shown in the foreground).
- Detach the video switcher window by pressing on the icon in its top left corner (once detached, you can move and resize the window just like any other in your OS).
If you close the detached window the switcher will re-lock to the QGC Fly view.
If supported by the camera and vehicle, _QGroundControl_ can start and stop video recording on the camera itself. _QGroundControl_ can also record the video stream and save it locally.
Video stream recording is controlled on the [video stream instrument page](#video_instrument_page).
Press the red circle to start recording a new video (a new video file is created each time the circle is pressed); the circle will change into a red square while recording is in progress.
