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.

|---|---|---|---|
Radiation Front End (ADA-R) |
The Radiation Front End collects data from the Pyranometer CMP22, Pyrgeometer CGR4 and Radiation Thermometer KT19.85II. |
210 x 330 x 104 |
4.5 |
Nose Front End (ADA-N) |
The Nose Front End collects data from the temperature, humidity and pressure sensors in the nose compartment, data of the hygrometer CR-2 and data from the Turbulence Nose Boom if installed. |
276 x 260 x 105 |
4.3 |
Central Front End (ADA-C) |
The Central Front End receives data from several instruments such as the navigation systems IRS, Radar Altimeter and Air Data Computer. It also collects the data from the GPS Receivers. |
449 x 483 x 195 |
9.6 |
Server Box (ADA-S) |
The Server Box ADA-S hosts two Linux servers for data storage (DMS1 and DMS2) and one Windows server (dms-operator) for operation of the system. |
449 x 483 x 195 |
14.0 |
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/.
