Human-machine interface architecture in an aircraft

A human-machine interface method configured to enable interactions between aeronautical applications and aircraft control and display instruments, said method being executed by a human-machine interface system comprising:

• an interface server in which the aeronautical applications and control and display managers are connected, each control and display manager being associated with a control and display instrument and performing an abstraction of the associated control and display instrument;
• application extension libraries;
• and
• at least one control and display utility extension library, the method comprising the following steps performed by the interface server:
• communicating with each aeronautical application and each control and display manager using a common core protocol;
• calling up the application extension libraries in order to obtain an implementation of the common core protocol dedicated to each aeronautical application, as well as a display window definition which is dedicated to each aeronautical application and which has a part which is agnostic to any display technology and another part which is specific to a display technology;
• and
• calling up said at least one control and display utility extension library in order to obtain an implementation of the common core protocol dedicated to the control and display managers.
