Mavic 2 Pro/Zoom User Manual Return to Home The Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios in detail. GPS Description If a strong GPS signal was acquired before takeoff, the Home Point is the location from which the aircraft launched. The GPS signal strength is Home Point indicated by the GPS icon ( ). The Aircraft Status Indicator will blink green quickly when the Home Point is recorded. Smart RTH If the GPS signal is sufficiently strong, Smart RTH can be used to bring the aircraft back to the Home Point. Smart RTH is initiated either by tapping in the DJI GO 4 app (and following the on-screen instructions) or by pressing and holding the RTH button on the remote controller. Exit Smart RTH by tapping in the DJI GO 4 app or by pressing the RTH button on the remote controller. Low Battery RTH Low Battery RTH is triggered when the Intelligent Flight Battery is depleted to the point that the safe return of the aircraft may be affected. Return home or land the aircraft immediately when prompted. DJI GO 4 will display a warning when a low battery level warning is triggered. The aircraft will automatically return to the Home Point if no action is taken after a ten-second countdown. The user can cancel the RTH procedure by pressing the RTH button or Flight Pause button on the remote controller. If the RTH procedure is cancelled following a low battery level warning, the Intelligent Flight Battery may not have enough charge for the aircraft to land safely, which may lead to the aircraft crashing or being lost. The thresholds for the battery level warnings are automatically determined based on the aircraft’s current altitude and distance from the Home Point. The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from its current altitude. The user cannot cancel the auto landing but can use the remote controller to alter the aircraft’s orientation during the landing process.
