Software Configurable Air Data Unit

Product Code: SCADU

The Curtiss-Wright Controls Integrated Sensing (CWCIS) Software Configurable Air Data Unit (SCADU) is intended to be the primary supply of air data parameters to the aircraft systems.

The SCADU calculates the air data parameters from information received from the pitot and static pressure sensors and an outside air temperature probe. This computed information is supplied to other aircraft systems via an ARINC 429, analogue dc or discrete signals. Its unique design provides a product, which is robust, can be hard mounted in any orientation, but is extremely light in weight, and is easily configurable.

Using newly developed electronic applications, SCADU negates the need for aircraft volumes and restrictors thus reducing aircraft weight and maintenance.

The SCADU is constructed as a rugged aluminum enclosure and is designed for mounting in any orientation on its base plate via four holes in the flange. The SCADU weighs less than 1.3 kg.

The majority of the SCADU parameters can be configured by software to tailor the unit for a specific aircraft type. Up to 15 configurations can be stored in the unit, selectable by a combination of four wires in the aircraft.
