Издание на английском языке
British Admiralty Instructional Paper Charts are useful for training and examination purposes. They are not maintained for the latest information and should not be used for navigation. The UKHO (United Kingdom Hydrographic Office) provides these charts to be used by students to practice traditional chart work. They are often used by maritime colleges and nautical schools to test their students in navigation practice.
