Fly View

The Fly View is used to command and monitor the vehicle when flying.

You can use it to:

Fly View

UI Overview

The screenshot above shows the main elements of the fly view:

  • Map: Displays the positions of all connected vehicles and the mission for the current vehicle.
    • You can drag the map to move it around (the map automatically re-centres after a certain amount of time).
    • Once flying, you can click on the map to set a Go to or Orbit at location.
  • Fly Toolbar: Key status information for sensors (GPS, battery, RC control), and vehicle state (Flight mode, Armed/Disarmed status).
    • Select the sensor indicators to view more detail.
    • Press the Flight mode text (e.g. "Hold") to select a new mode. Not every mode may be available.
    • Press the Armed/Disarmed text to toggle the armed state. If flying you can press this text to Emergency Stop.
  • Fly tools: You can use these to:
    • Toggle between takeoff/land.
    • Pause/restart the current operation (e.g. landing, or the mission).
    • Safety return (also known as RTL or Return).
    • The Action button offers other appropriate options for the current state (these overlay the Confirmation Slider). Actions include changing the altitude or continuing a mission.
    • Enable the preflight checklist (tool option disabled by default).
  • Instrument Panel: A multi-page widget that displays vehicle information including: telemetry, camera, video, system health, and vibration.
  • Video/Switcher: Toggle between video or map in a window.
    • Press the element to switch Video and Map to foreground.
    • QGroundControl supports RTP and RTSP video streaming over your vehicles UDP connection. It also support directly connected UVC device support. QGC video support is further discussed in the Video README.
  • Confirmation Slider: Context sensitive slider to confirm requested actions. Slide to start operation. Press X to cancel.

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.

Instrument Panel

The instrument panel is a multi-page widget that displays information about the current vehicle, including: telemetry, camera, video, system health, and vibration information.

The default page displays vehicle telemetry - use the drop down menu on the to right to select the other options.

Values (Telemetry)

The values page shows telemetry information; by default the altitude (relative to the home location) and the ground speed.

Instrument Page - for values/telemetry

You can configure what information is display by pressing the small gear icon on the top left of the panel. Each value can be displayed in normal or "large" size (large size shows just one value per row in the page, while normal shows 2).

Instrument Page - values settings

Camera

The camera page is used to configure and control the camera. For a camera connected directly to the Flight Controller the only available option is camera triggering:

Instrument Page - for Camera

When connected to camera that supports the MAVLink Camera Protocol 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.

Instrument Page - Camera MAVLink Settings

Advanced settings can be changed via the gear icon at the top left of the page.

Instrument Page - Camera MAVLink Settings

Most of the settings that are displayed depend on the camera (they are defined in its MAVLink Camera Definition File). 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)

Video Stream

The video page is used to enable/disable video streaming. When enabled, you can start/stop the video stream, enable a grid overlay, change how the image fits the screen, and record the video locally with QGC.

Instrument Page - Video Stream

Health

The health page shows you the health of the systems within your vehicle. QGroundControl will switch to this page automatically if any systems change to unhealthy.

Instrument Page - Vehicle Health Good Instrument Page - Vehicle Health Bad

Vibration

The vibration page shows current vibration levels and clip counts.

Instrument Page - Vibration Clip

Actions/Tasks

The following sections describe how to perform common operations/tasks in the Fly View.

Many of the available options depend on both the vehicle type and its current state.

Pre Flight Checklist

An automated preflight checklist can be used to run through standard checks that the vehicle is configured correctly and it is safe to fly.

To you the checklist, first enable the tool by navigating to Application Settings > General > Fly View and selecting the Use preflight checklist checkbox. The tool will then be added to the Flight Tools. Press it to open the checklist:

Pre Flight Checklist

Once you have performed each test, select it on it in the UI to mark it as complete.

Arm

Generally QGroundControl does not require you to arm the vehicle explicitly; this is done for you if you start a mission or takeoff.

Arming a vehicle starts the motors in preparation for takeoff.

To arm the vehicle, select Disarmed in the Fly Toolbar and then use the confirmation sider.

Arm

Vehicles usually disarm automatically if you do not take off after a few seconds.

Disarm

Disarming the vehicle stops the motors (making the vehicle safe). To disarm the vehicle select Armed in the Fly Toolbar when the vehicle is landed.

Disarm

Disarming the vehicle while it is flying is called an Emergency Stop

Emergency Stop

Emergency stop is effectively the same as disarming the vehicle while you are flying. Your vehicle will crash!

To disarm the vehicle select Armed in the Fly Toolbar when the vehicle is flying.

Emergency Stop

Takeoff

If you are starting a mission for a multicopter QGroundControl will automatically perform the takeoff step.

To takeoff (when landed):

  1. Press the Takeoff button in the Fly Tools (this will toggle to a Land button after taking off).
  2. Optionally set the takeoff altitude in the right-side vertical slider.
  3. Confirm takeoff using the slider.

takeoff

Land

You can land at the current position at any time while flying:

  1. Press the Land button in the Fly Tools (this will toggle to a Land button when landed).
  2. Confirm landing using the slider.

land

RTL/Return

Return to the home position at any time while flying:

  1. Press the RTL button in the Fly Tools.
  2. Confirm RTL using the slider.

land

The vehicle may also land at the home position, depending on its type and configuration.

Change Altitude

You can change altitude while flying, except when in a mission:

  1. Press the Action button on the Fly Tools
  2. Select the Change Altitude action from the dialog.

    Continue Mission/Change Altitude action

  3. Move the vertical slider to the desired altitude, then drag the confirmation slider to start the action.

    Change altitude

Goto Location

After taking off you can specify that you want to fly to a particular location.

  1. Press the map where you want the vehicle to move and select Go to location on the popup.

    Goto or orbit

  2. The location will be displayed on the map, along with a confirmation slider.

    Goto confirmation

  3. When you're ready, drag the slider to start the operation (or press the X icon to cancel it).

Orbit Location

After taking off you can specify that you want to orbit a particular location.

  1. Press on the map (near the centre of your desired orbit) and select Orbit at location on the popup.

    Goto or orbit

  2. The proposed orbit will be displayed on the map, along with a confirmation sider.

    Orbit confirmation

    • Select and drag the central marker to move the orbit location.
    • Select and drag the dot on the outer circle to change the orbit radius
  3. When you're ready, drag the slider to start the operation (or press the X icon to cancel it).

Pause

You can pause most operations, including taking off, landing, RTL, missions, Orbit at location. The vehicle behaviour when paused depends on the vehicle type; typically a multicopter will hover, and a fixed wing vehicle will circle.

You cannot pause a Goto location operation.

To pause:

  1. Press the Pause button in the Fly Tools.
  2. Optionally set a new altitude using the right-side vertical slider.
  3. Confirm the pause using the slider.

Missions

Start Mission

You can start a mission when the vehicle is landed (the start mission confirmation slider is often displayed by default).

To start a mission from landed:

  1. Press the Action button on the Fly Tools
  2. Select the Start Mission action from the dialog.

    Start mission action

    (to display the confirmation slider)

  3. When the confirmation slider appears, drag it to start the mission.

    Start mission

Continue Mission

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 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 you place in the mission).

You can continue the current mission while (unless already in a mission!):

  1. Press the Action button on the Fly Tools
  2. Select the Continue Mission action from the dialog.

    Continue Mission/Change Altitude action

  3. Drag the confirmation slider to continue the mission.

    Continue Mission

Resume Mission

Resume Mission is used to resume a mission after performing an RTL/Return or Land from within a mission (in order, for example, to perform a battery change).

If you are performing a battery change, do not disconnect QGC from the vehicle after disconnecting the battery. After you insert the new battery QGroundControl will detect the vehicle again and automatically restore the connection.

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.

Resume Mission

If you select to resume the mission, then QGroundControl will rebuild the mission and upload it to the vehicle. Then use the Start Mission slider to continue the mission.

The image below shows the mission that was rebuilt after the Return shown above.

Resume Rebuilt Mission

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.

Remove Mission Prompt After Landing

You will be prompted to remove the mission from the vehicle after the mission completes and the vehicle lands and disarms. This is meant to prevent issues where stale missions are unknowingly left on a vehicle, potentially resulting in unexpected behavior.

Display Video

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 (below we show the video in the foreground).

Video Stream Record

Video streaming is configured/enabled in Application Settings > General tab > Video.

You can further configure video display using controls on the switcher:

Video Pop

  • Resize the switcher by dragging the icon in the to right corner.
  • Hide the switcher by pressing the toggle icon in the lower left.
  • 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.

Record Video

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 stored on the camera may be of much higher quality, but it is likely that your ground station will have a much larger recording capacity.

Record Video Stream (on GCS)

Video stream recording is controlled on the video stream 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.

Video Stream Record

Video stream recording is configured in the Application Settings > General tab:

  • Video Recording - specifies the recording file format and storage limits.

    Videos are saved in Matroska format (.mkv) by default. This format is relatively robust against corruption in case of errors.

  • Miscellaneous - Streamed video is saved under the Application Load/Save Path.

The stored video includes just the video stream itself. To record video with QGroundControl application elements displayed, you should use separate screen recording software.

Record Video on Camera

Start/stop video recording on the camera itself using the camera instrument page. First toggle to video mode, then select the red button to start recording.
