Obstacle Avoidance During FailSafe RTH
Aircraft can now sense and actively attempt to avoid obstale during FailSafe RTH, provided that the light
condition is ideal for the Obstacle Sensing System. The details on how the aircraft will behave during
obstacle avoid is listed below:
1. Aircraft decelerates when an obstacle is sensed at 65 feet (20 meters) ahead.
2. Aircraft stops and hover then start ascending vertically to avoid the obstacle. Eventually, the aircraft will
stop climbing when it is at least 16 feet (5 meters) above the detected obstacle.
3. Failsafe RTH procedure resume, the aircraft will continue flying to the Home Point at the current
altitude.
TapFly
Introduction
With the TapFly feature, use now can tap on the mobile device screen to guide the aircraft to fly toward the
designated direction without using the remote controller. Aircraft can automatically avoid obstacle or initiate
break and then hover automatically during the flight, provided that the lighting is not too dark ( < 300 lux) nor
too bright ( > 10,000 lux).
Using TapFly
Ensure the battery level is more than 50 % for the Intelligent Flight Battery. And the aircraft is in P-mode.
Then follow the steps below to use TapFly:
Take off and ensure the aircraft is flying at least 9 feet (3 meters) above the ground.
3 meters
ON OFF
Auto Hold
To ensure the aircraft is heading towards the static direction, you cannot rotate the aircraft
during FailSafe RTH while Obstacle Sensing System is enabled.
The aircraft cannot avoid the obstacle that is is direct above the aircraft.
