15.1.1 Stabilization system is a system intended
to stabilize the main parameters of the craft's attitude: heel, trim,
course and height and minimize the craft's motion: roll, pitch, yaw
and heave.
15.1.2 Self-stabilization of the craft is stabilization
ensured solely by the craft's inherent characteristics.
15.1.3 Forced stabilization of the craft is stabilization
achieved by:
-
(a) an automatic system; or
-
(b) a manually assisted system; or
-
(c) a combined system incorporating elements of
both automatic and manually assisted stabilization systems.
15.1.4 Augmented stabilization is a combination
of self-stabilization and forced stabilization.
15.1.5 The main elements of a stabilization system
are as follows:
-
(a) stabilization devices such as rudders, foils,
flaps, skirts and jets;
-
(b) power drives actuating stabilization devices;
and
-
(c) stabilization equipment for accumulating and
processing data for making decisions and giving commands such as sensors,
logic processors and automatic safety control.
15.1.6 An 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.
15.1.7 For the purposes of this chapter "stabilization
device" means devices with the aid of which forces for controlling
the craft's position are generated (rudders, foils, flaps, fans, skirts,
water jets, pumps, etc.).
