English is the international language of science, technology and human relations. It is also the language of the aerospace and defense industry. However, it is not often the native language of the readers of technical documentation. Many readers have a limited knowledge of English. Complex sentence structure and the large number of meanings and synonyms that many English words have can cause confusion.

In aviation, it is important to correctly understand maintenance and operation documentation to make sure that systems operate safely and correctly and to protect human lives.
