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.
The Front LEDs show the orientation of the aircraft. The Front LEDs glow solid red when the aircraft is turned
on to indicate the front (or nose) of the aircraft. The Aircraft Status Indicators communicate the system status
of the ight controller. Refer to the table below for more information about the Aircraft Status Indicators:
