What will the drone do on signal loss?

Will it continue its mission or return to home (RTH)?

Your aircraft will automatically cancel the flight mission if it loses connection for several seconds. Then it will perform Remote-Controller-Signal-Lost action, which is set to RTH by default. You can cancel RTH by pressing the RTH button on your remote controller after your aircraft is connected again. The drone will then hover in the sky and wait for your next command. For more details on RTH, please read the DJI guidelines carefully.

As said above, RTH is the default setting of Remote-Controller-Signal-Lost action. But it can be set to other values, e.g. land on the ground or hover in the sky after the signal is lost. To change this option, please go to the “Advanced Settings” section in DJI Go.

Besides, for the “On Signal Loss” option in Altizure app, you can also set it as “Continue Mission”. In that case, your aircraft will not cancel the flight even when it loses signal from remote controller.

However, this is a dangerous move because you may lose track of your drone if:

1) “Continue Mission on Signal Loss” option is activated.
2) The drone has been disconnected for a long time.
3) Battery runs below the “Critically Low Battery Warning” level before the mission is completed (please find the “Critically Low Battery Warning” threshold in DJI Go).

The above situations are dangerous because:

  • DJI firmware force aircraft to land if battery is below the “Critically Low Battery Warning” level.
  • If a mission is neither completed nor canceled, DJI firmware will not activate RTH when the battery gets low.
  • The aircraft cannot receive RTH signal from app or remote controller when it is disconnected.
