These performance standards harmonize the requirements for
the presentation of navigation-related information on the bridge of
a ship to ensure that all navigational displays adopt a consistent
human machine interface philosophy and implementation.
These performance standards supplement and, in case of a conflict,
take priority over, presentation requirements of the individual performance
standards adopted by the Organization for relevant navigational systems
and equipment, and cover the presentation of navigation-related information
by equipment for which performance standards have not been adopted.
