16.1.1
Stabilization control system is
a system intended to stabilize the main parameters of the craft's
attitude: heel, trim, course and height and control the craft's motions:
roll, pitch, yaw and heave. This term excludes devices not associated
with the safe operation of the craft, e.g. motion-reduction or ride-control
systems.
The main elements of a stabilization control system may include
the following:
-
.1 devices such as rudders, foils, flaps, skirts,
fans, water jets, tilting and steerable propellers, pumps for moving
fluids;
-
.2 power drives, actuating stabilization devices;
and
-
.3 stabilization equipment for accumulating and
processing data for making decisions and giving commands such as sensors,
logic processors and automatic safety control.
16.1.2
Self-stabilization of the
craft is stabilization ensured solely by the craft's inherent characteristics.
16.1.3
Forced stabilization of the
craft is stabilization achieved by:
-
.1 an automatic control system; or
-
.2 a manually assisted control system; or
-
.3 a combined system incorporating elements of
both automatic and manually assisted control systems.
16.1.4
Augmented stabilization is
a combination of self-stabilization and forced stabilization.
16.1.5
Stabilization device means
a device as enumerated in 16.1.1.1 with the aid of which forces for
controlling the craft's position are generated.
16.1.6
Automatic safety control is
a logic unit for processing data and making decisions to put the craft
into the displacement or other safe mode if a condition impairing
safety arises.
