Rawdata storage on board
Metadata (Metadata Plugin) |
---|
| During flight FGGA data are stored within the rack unit. Analog 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). |
