2On safety
This chapter provides information that concerns your own safety as well as the safety of
the plant operator.
Please read this chapter carefully before working with the APS.
2.1 Qualified safety personnel
APS must be installed, commissioned, and maintained only by adequately qualified
personnel.
A person is considered qualified safety personnel if he/she
•Has sufficient skills in the field of the respective equipment based on his/her technical
training and experience and
•Has been instructed by the manufacturer on system operation and all applicable safety
guidelines and
•Is familiar with all relevant country-specific occupational safety regulations, work safety
regulations, guidelines, and generally accepted technical rules and standards (e.g.,
DIN standards, VDE regulations, country-specific rules) to such an extent that he/she is
able to evaluate the safe condition of the power-driven machinery and he/she
•Has access to and has read the operating instructions.
2.2 Intended use
APS is a driver assistance system for aircraft tractors without tow bars at airports. The
system gives the driver visual and acoustic warnings of possible obstacles during the
towing process. The towing processes Towing/maneuvering, Push-back and Enter/exit
hanger are supported.
A 2D LiDAR sensor mounted on the rear of the tractor detects the aircraft type to be
monitored as the nose landing gear is engaged. APS uses this to determine the size and
geometry of the towing corridor, thereby supporting a three-stage monitoring and warning
concept for the wing and rear hazardous points.
The towing corridor is continuously monitored during the towing process. The monitored
area includes everything that is within the field of view of the 2D LiDAR sensor and can be
shown on the display.
The towing corridor is also the danger zone in which visual, and optionally also acoustic
warnings of possible obstacles are issued. A warning zone enclosing the aircraft contour
allows visual and acoustic warning of imminent collisions.
APS detects only objects which are visible in the measurement plane of the 2D LiDAR
sensor. The 2D LiDAR sensor must therefore have an unobstructed view of the area to
be monitored.
Using APS means that hazardous situations, such as parked vehicles, ground equipment,
staircases, landing gear blocks, insufficiently opened hanger doors or incorrectly
positioned aircraft, are detected in a timely manner and that accidents during the towing
process are avoided.

•APS is a driver assistance system. This means that at all times the driver bears the full
responsibility for safe operation, in particular for people who are in the danger zone of
the vehicle.
•APS is not a safety device for human protection and therefore does not comply with
any safety standards. For safety applications, please contact SICK AG.
In the event of any other usage or of modification to the system –including in the context
of mounting and installation –any claims against SICK AG under the warranty will be
rendered void.
2.3 General safety notes and protective measures
2.3.1 Safety notes and symbols
The following safety and hazard notes are used for your own safety, for the safety of third
parties, and for the safety of the machine. You should therefore observe them at all times.
DANGER
Denotes an immediate hazard that may result in severe to fatal injuries.
The pictogram shown on the left-hand side of the note refers to the type of hazard in
question (the example here shows a risk of injury resulting from electrical current).
WARNING
Denotes a potentially dangerous situation that may result in severe to fatal injuries.
The pictogram shown on the left-hand side of the note refers to the type of hazard in
question (the example here shows a risk of damage to the eye by laser radiation).
WARNING
Denotes a potentially dangerous situation that may result in minor personal injury or
possible material damage.
NOTE
Denotes a potential risk of damage or functional impairment of the device or the devices
connected to it.
This symbol refers to supplementary technical documentation.

2.3.2 General safety notes
APS has been designed in a way that allows for safe operation. However, a certain level
of risk will always remain.
Awareness of potential sources of danger in the system will help you to work in a safer
manner and thus prevent accidents.
To avoid risks, please also observe the special warnings in each of the individual
chapters.
WARNING
Safety notes
Observe the following to ensure the safe use of the system as intended.
•The notes in these operating instructions must be complied with.
•All official and statutory regulations governing the operation of the system must be
complied with.
•The national and international legal specifications apply to the installation and use of
the system, to its commissioning, and to recurring technical inspections, in particular:
–The accident prevention regulations and work safety regulations
–Any other relevant safety regulations
•The checks must be carried out by qualified safety personnel or specially qualified and
authorized personnel, and must be recorded and documented to ensure that the tests
can be reconstructed and retraced at any time.
•These operating instructions must be made available to the operator of the system.
The system operator must be instructed by qualified safety personnel and read the
operating instructions.
•The driver must follow relevant instructions and conduct inspections in order to ensure
that the screen of the 2D LiDAR sensor is clean and undamaged.
•The 2D LiDAR sensor must have a free field of view. The sensor head must not be
covered by other objects, for example.
•SICK AG recommends carrying out a system check before commissioning the system.
WARNING
Risk resulting from improper operation
Improper installation and commissioning, damaged components, and unsuitable ambient
conditions such as excessively cold or warm temperatures and high levels of dust, fog
or spray, may cause faults and faulty alarms and may result in a complete system crash.
