Low Battery Failsafe
Environmental conditions can affect power consumption. Use the Mission Planner Flight Data
display to monitor the voltage of the battery during flight.
If the battery reaches 13.8 V, the Aero will return automatically to circle above the launch point,
indicated by a blinking yellow status LED and a quick repeating tone.
The Aero is programmed with a set of failsafe behaviors to prevent a crash in the event of a loss
of one of the data or communication channels required for autonomous flight. Although certain
failsafe have assigned LED indicators and tones, it is unlikely that you will be able to see these at a
distance. Monitor the Flight Data screen for failsafe indications. If a failsafe is triggered, the assigned
behavior will activate. To override the failsafe behavior (RTL in most cases), use the controller to
regain manual control.
Regaining Manual Control
To regain manual control during the mission, switch to fly-by-wire mode using the controller. If
you’re a confident operator, switch to stabilize mode. If you observe instability in the Aero’s flight
behavior or it the aircraft moves outside your designated safe flying area, switch to RTL. Turning off
the controller will automatically trigger an RTL and can be used in an emergency situation as a hard
recall command.
RC Controller Signal Failsafe
Physical obstructions and interference from nearby wireless signals can affect the Aero’s connec-
tion with the RC controller.
If the Aero loses contact with the controller, it will return to the launch point automatically and
enter into a circle pattern above the launch point, indicated by a blinking yellow status LED.
If the controller failsafe is triggered, wait for the Aero to return to the launch point, then regain
manual control and either land or restart the mission.
