DANGER
Obviously recognizable damages or defects
This may result in adverse effect while flying the aircraft. Aircraft or parts of it
may fall down on ground.
Precautions:
▶ Make sure the assembly of the aircraft shows no damages.
▶ Check every part of the aircraft after any crash or violent impact. If
any problems or questions arise, contact your local Leica Geosystems cus-
tomer support.
DANGER
Critical low batteries
Crash landing due to critical low batteries. Risk of serious injuries and dam-
ages because of falling device. To prevent a crash landing due to low bat-
teries, the BLK2FLY starts an automatic descent depending on the current
altitude. Once started, this procedure cannot be interrupted. Controlling the
position and heading is possible.
Precautions:
▶ Always monitor the battery state of charge of the batteries.
▶ Respect the warning signals for low batteries.
▶ Keep in mind to plan an energy reserve for coming back and landing.
▶ Environmental conditions, for example wind, are not taken into account
when automatic reserve planning is done.
▶ Be aware of, that the diversion from direct flight trajectory due to
obstacle avoidance is not taken into account for reserve planning.
DANGER
Crash due to own downwash
The device can fly in his own turbulences. Risk of serious injuries and damages
because of falling device.
Precautions:
▶ Avoid a straight vertical descent.
▶ Descend in spiral movements or in a 'zig-zag' motion.
▶ Be aware of the downwash of the rotor blades when flying near ground.
DANGER
Crash due to weak batteries at low outdoor temperatures
At low outdoor temperatures, the batteries cannot provide their full energy.
Risk of serious injuries and damages because of falling device.
Precautions:
▶ Respect the general limitations.
▶ Keep batteries warm before operating the device at low outdoor temper-
atures.
▶ Do not fly batteries which are colder than 10 °C. Flight time is shortened.
