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

Home process may be interrupted and the pilot given control of the aircraft if the remote controller signal
connection is re-established.

feet (20 meters) radius of the Home Point. Aircraft will stop ascending and immediately return
to the Home Point if you move the left stick if the aircraft reaches 65 feet (20 meters) altitudes or
beyond during Failsafe.
The aircraft cannot avoid obstruction during Failsafe RTH if Forward Vision System is disabled.

enter “Camera” 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
