Description and Emergency action
Your swinglet CAM can no longer calculate its posi-
tion, making it impossible for it to know where it is
and thus to navigate.
Emergency action: The drone turns off its motor,
sets a bank angle and glides in a large circle towards
the ground. If there is a strong wind the drone may
be pushed far from its current position. If satellite sig-
nals are re-acquired the drone will abort the landing
procedure and go to the Home waypoint.
The battery is completely empty.
Emergency action: The drone turns off its motor
and glides towards the ground in the direction of the
Home waypoint. This error is always preceded by a
Low battery In-flight warning.
There is a failure with the orientation sensors which
makes it impossible for the drone to stabilise itself
and thus initiate a gliding emergency landing.
Emergency action: The drone turns off its motor
and fully deflects its ailerons which results in an un-
controlled descent with limited impact energy (deep
stall or spin).
