Return-to-Home (RTH)

The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are

three types of RTH procedures: 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 was launched. The GPS signal

strength is indicated by the GPS icon (

). The aircraft status

indicator will blink rapidly when the home point is recorded.

Smart RTH

Use the RTH button on the remote controller (refer to “RTH button” on page 26 for more information)

or tap the RTH button in the DJI GO app and follow the on-screen instructions when GPS is available to

initiate Smart RTH. The aircraft will then automatically return to the last recorded Home Point. You may use

the remote controller’s control sticks to control the aircraft’s position to avoid a collision during the Smart

RTH process. Press and hold the Smart RTH button once to start the process, and press the Smart RTH

button again to terminate the procedure and regain full control of the aircraft.
