(Learn how and when to remove these template messages) Mechatronics is a multidisciplinary field of science that includes a combination of mechanical engineering, electronics, computer engineering, telecommunications engineering, systems engineering and control engineering. As technology advances, the subfields of engineering multiply and adapt.
Advertisement. Avionics engineering is a sub field of Aeronautical engineering and deals with electronic systems that are used on aircraft, artificial satellites and spacecrafts.Basically it deals with the systems that are required in order for the plane to work seamlessly.vionics Engineering has been divided into two major sub-fields; Aircraft avionics and Mission/Tactile avionics. Subsequent sub-disciplines are as follows; 1  Communications. 2  Navigation. 3  Monitoring. 4  Aircraft flight-control systems. 5  Collision-avoidance systems. 6  Black Boxes. 7  Weather systems.
