The Aircraft Data Acquisition System (ADA) consists of several systems, the Nose Front End (ADA-N), the Radiation Front End (ADA-R) and the Central Front End (ADA-C). All units connect to different sensors from which they gather data and transfer it on request to a data server. For this they have high speed data communication implemented on a FPGA, as well as precise timing algorithms, for keeping the units in an accurate execution. A Web-GUI allows to view the application with a standard web browser. This GUI provides the user additional status information and allows to edit the configuration of the system. The systems are programmed with LabVIEW and installed on a National Instruments CompactRIO cRIO 9025 platform with several IO modules. All components are powered by 28 VDC. The Nose Front End is installed in the nose compartment of the aircraft while the other front ends are installed in racks. The Nose Front End communicates with the Central Front End via a permantently installed fibre optic cable.

After flight data are stored on a land-based instance of the Data Management System (https://dms.awi.de/). From there data can be ordered in a self-selected way by creating order templates. Data are only available after agreement of the campaign leader.
Here you can find a list of devices and data you can extract from https://dms.awi.de/.

External Devices
Data of several devices and sensors can not be stored automatically within in the DMS framework. They are downloaded from operator PCs or the devices themselves and copied to the DMS framework by hand. They can be found in the Data / External Devices folder of each flight.
