15.1 Definitions

  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.).
