9 Functional requirements for displays of INS

Parent topic: Module B - Task related requirements for Integrated Navigation Systems

9.1 General

  9.1.1 The INS should comply with the presentation requirements adopted by the Organizationfootnote.

  9.1.2 All essential information should be displayed clearly and continuously. Additional navigational information may be displayed, but should not mask, obscure or degrade essential information required for the display by its primary task, as specified in this performance standards.

  9.1.3 The INS should be capable of displaying data available from the sensors.

  9.1.4 The information should be displayed together with the indication of its source (sensor data, result of calculation or manual input), unit of measurement and status, including mode.

  9.1.5 Display and update of essential information available in the equipment as well as safety related automatic functions should not be inhibited due to operation of the equipment.

9.2 Default display configurations and operational modes

  9.2.1 The INS should offer default display configurations for the tasks route monitoring and collision avoidance selectable at each task station to provide the bridge team and pilot with a standardized display. This configuration should be accessible by a simple operator action. The basic requirements for these display configurations are specified in Appendix 6.

  9.2.2 The INS should provide operational modes for open sea, coastal, confined waters (pilotage, harbour berthing, anchorage).

  9.2.3 User-defined display modes

 It is recommended that the INS provides means to generate pre-defined or operator-defined display modes, that are optimally suitable to the navigation task.

  9.2.4 When switching the task from one task station to another, the current display configuration should be maintained.

9.3 Mode and status awareness

  9.3.1 The operational mode in use should be clearly indicated to the bridge team and pilot.

  9.3.2 If the mode in use is not the normal mode, to fully perform the functions required for the INS, this should be clearly indicated.

 Example of modes other than the normal mode are:

  • degraded condition modes, in which the INS cannot fully perform all functions
  • “service modes”
  • simulation mode
  • training (familiarization) mode
  • other modes, in which the INS cannot be used for navigation.

  9.3.3 If the system is in a degraded condition this should be sufficiently clear that the bridge team and pilot can understand the nature of the failure and its consequences.

  9.3.4 The INS should indicate the operational status of automated functions and integrated components, systems and/or subsystems.

9.4 Information display

  9.4.1 It should be possible to display the complete system configuration, the available configuration and the configuration in use.

  9.4.2 The INS should provide the means to display the type of data, source and availability.

  9.4.3 The INS should provide the means to display the type of function and availability.

  9.4.4 The INS should provide the means to display the device identification and its availability.

  9.4.5 Ships and system related parameters and settings should be displayed on demand.
