US Patent 12006060 Human-machine interface architecture in an aircraft

A human-machine interface system enables interactions between aeronautical applications and aircraft control and display instruments. The human-machine interface system comprises an interface server communicating, by virtue of a common core protocol, with the aeronautical applications and control and display managers performing an abstraction of control and display instruments. The human-machine interface comprises application extension libraries providing an implementation of the common core protocol dedicated to each aeronautical application, as well as a display window definition dedicated to each aeronautical application. The human-machine interface comprises at least one control and display utility extension library providing an implementation of the common core protocol dedicated to the control and display managers. Hence, a flexible, portable and reusable architecture with easy extension and scalability opportunities is provided.
