Return-to-Home (RTH)

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

Home Point

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 indicated

by the GPS icon (

Less than 4 bars is considered a weak GPS signal). The

aircraft status indicator will blink rapidly when the home point is recorded.

Failsafe RTH

The Forward Vision System allows the aircraft to create a real-time map of its flight route as it flies. If the

Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be

automatically activated if the remote controller signal is lost for more than three seconds. The aircraft

will plan its return route and retrace its original flight route home. The aircraft will hover for 10 seconds

at its current location. When it regains signal connection it will wait for pilot commands. The Return-to-

Home process may be interrupted and the pilot given control of the aircraft if the remote controller signal

connection is re-established.

Failsafe Illustration

Aircraft cannot return to the Home Point when GPS signal is weak or unavailable.

Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a

65 feet (20 meters) radius of the Home Point. When the RTH altitude is set to more than 20 m

and the aircraft is ascending between 20 m and the preset RTH altitude, the aircraft will stop

ascending and immediately return to the Home Point if you push the throttle stick.

The aircraft cannot avoid obstruction during Failsafe RTH if Forward Vision System is disabled.

It is important to set a suitable Failsafe altitude before each flight. Launch the DJI GO 4 app, tap

GO FLY and tap to set the Failsafe Altitude.

User cannot control the aircraft while the aircraft is ascending to 65 feet (20 meters) from the

current altitude. However, user can press RTH button once to exit ascending and regain control.

The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and

lighting conditions are sufficient. The aircraft will automatically climb up to avoid obstacles and

descend slowly as it returns to the home point. To ensure the aircraft returns home forwards, it

cannot rotate or fly left and right during RTH while the Forward Vision System is enabled.
