      In most situations, you can rely on Hovermap’s failsafes to help keep your system safe. However, if you do find yourself in a situation where your drone is behaving erratically and you need to take immediate control, use one of the following procedures.

      Important

      Before operation, make sure that you are familiar with your platform-specific emergency procedures.

      Note

      For more information on failsafes, go to Failsafes.

      Critical error or erratic drone behavior

      Switch to drone control mode

      If a critical error (in red) appears, or if your drone is behaving erratically, do the following:

      1. Switch to drone control by changing the flight mode switch out of Hovermap mode.
        If GPS is available, switch to the appropriate position hold mode.
        If GPS is not available, switch to Atti mode (for DJI).

      2. Manually fly the drone home safely.

      3. Keep a close eye on your drone, as the controls will be sensitive and it will move at greater speed.

      4. Contact Technical Support Services with flight logs and scan data for more details about any errors encountered.

      Warning

      This procedure should only be used in an emergency. Avoid flying in drone control mode unless you are an experienced pilot.

      Note

      For more detailed information on notifications, refer to Hovermap notifications.

      Loss of tablet control
      Switch to Pilot Assist mode
      If you are flying in Autonomous mode and need to revert to Pilot Assist mode, use the following procedure. There are a number of reasons why you would want to do this, such as losing the connection between the drone and the tablet (for example, if the Wi-Fi connection has been lost or the tablet battery has been drained).

      1. Tap the Pilot Assist button then confirm the action when prompted. Ensure that the switch is returned to the Hovermap position.

      2. The system will change to Pilot Assist mode. Shield will be activated and position control will be active.

      3. Manually fly the drone back to the home location or to a safe recovery location.

      4. Once you have reached this location, land the drone by one of the following methods: 

        • Descend until the Shield limit is reached, then switch to drone control using the flight mode switch. If no GPS is available, this will put the system into Atti mode. Carefully land the drone.

        • Allow the drone to hover at the home location until the critical battery autolanding failsafe is activated. Once the failsafe is triggered, the drone will land of its own accord.
