ISO 16329:2003规定了在下列条件下运行的船舶上安装的航向控制系统的结构、性能、检查和测试: 速度超过30千牛至70千牛；最大转弯速率20°/s；根据HSC规范第13章的要求，70°N至70°S之间的正常工作范围应符合这些标准中规定的最低性能要求。 ISO 16329:2003适用于航向控制系统，该系统使船舶能够在与船舶机动性及其航向信息源相关的限制内，以船舶舵机的最小操作保持预设航向。

ISO 16329:2003 specifies the structure, performance, inspection and testing of heading control systems to be installed on board crafts operating under the following conditions:

1. speed exceeding 30 kn and up to 70 kn;
2. maximum rate of turn 20°/s;
3. the normal range of operation between 70°N and 70°S should, as required by chapter 13 of the HSC Code, comply with the minimum performance requirements specified in these standards.

ISO 16329:2003 applies to the heading control systems which enable a craft to keep a preset heading with minimum operation of the craft's steering gear, within limits related to the craft's manoeuvrability in conjunction with their sources of heading information.
