Temperature out
of working levels
The temperature sensor on the drone is registering
internal temperatures of less than -50
◦
C or more
than 90
◦
C. This may occur in extremely hot or cold
environments or if the on-board autopilot is dam-
aged.
Security action: The drone flies towards the Home
waypoint at an altitude defined by the Home way-
point’s Change altitude parameter (by default, set to
‘Highest’).
User action: Land as soon as possible. If the out-
side temperature is above 35
◦
C or below -10
◦
C, dis-
connect the battery and wait until the temperature
changes to within these limits.
Above working
area ceiling
The drone has passed the vertical boundary of the
working area, defined by the working area ceiling.
This may occur if waypoint altitudes are set close to
or outside the working area or due to strong wind.
Security action: The drone flies towards the Home
waypoint at an altitude defined by the Home way-
point’s Change altitude parameter (by default, set to
‘Highest’). It also turns off its motor as long as it re-
mains above the working area ceiling.
User action: Limit the altitude of all waypoints to
less than the working area ceiling.
