06 Jul History of avionics
Until the 60s, avionics was primarily in the form of electromechanical flight instruments, each dedicated to a single information (pressure sensors, altimeters, temperature control instruments, etc.).
Since then, the use of information technology provides the ability to process all information instead of simply collect and transmit them to the driver. It is therefore no more than make a dash by bringing together independent instruments but to design and implement a global electronic flight system.
The sector therefore began its transformation to integrated architectures that must take into account in their design permanent evolution needs to contain costs.
The avionics are used to present the pilot with all information useful to it in maintaining flying his plane, its navigation, its communications with organizations in air traffic and allow him to interact with his plane.
They are grouped on the panel as close as possible to the driver. The four basic instruments are always arranged in the same way (in basic configuration T): the artificial horizon in the center, the anemometer on his left, the altimeter on his right, the directional gyro or drive tray below . This arrangement optimizes the visual system during flight. Available to other instruments is relatively standard but varies from one plane to another.
Positioned on the dual applications, ie both civilian and military, Elisa expands its markets and depend less on defense.
Avionics remains an emerging sector, the aircraft construction sector which is expected to generate the highest rate expansion. Elisa Avionics produces systems
and integrated modular avionics, the electroluminescent displays, flight control systems and landing systems assisted navigation and anemometer.
