Rawdata storage on board
| Metadata (Metadata Plugin) |
|---|
|
During flight FGGA data are stored within the rack unit. Analogue data of the methane concentration are also stored within the DMS system. |
Data archiving on land
| Metadata (Metadata Plugin) |
|---|
|
After the flight FGGA data have to be downloaded and are stored within the external devices file system of the aircraft data managment system (DMS). |
