LISAT ANSP Data Download Service
The LISAT ANSP Data Download service is intended to allow ANSPs to download the LISAT data in bulk so that it can be imported into other applications such as spreadsheets for more specific analysis.
The service is accessed via the ‘LISAT Data Downloads’ online service available to registered users via the EUROCONTROL extranet.
After selecting the LISAT Data Download service and entering your OneSky login and password you will be presented with a screen like the one shown below:
You then select from the drop down list presented which ATSU you would like to download data for and the dates between which you are interested and then click the ‘Go’ button.
You request will be logged and the status will be shown as ‘ Waiting’ as shown below.
The request are processed periodically (every few minutes) and once the data is available for download the status will change to ‘ Done’ and a ‘ Download’ link will be presented as shown below.
Clicking on the download link will allow you to download a zipped csv file containing an extract from the LISAT logs for the ATSU and dates you selected. The file contains a set of data as described in the table below. If you would like other data to be made available via this service please contact the CRO.

|SESSION_ID||A unique identifier (generated by LISAT) for the CM or CPDLC session. Note CM and CPDLC sessions can share a session id i.e. a CM session id is unique within all CM sessions and a CPDLC session id is unqiue within all CPDLC sessions but a session id is not unique within all CM and CPDLC sessions combined.|
|SESSION_STARTTIME||The time at which the CPDLC start request was sent.|
|SESSION_ENDTIME||The time at which the CPDLC session ended, normally when the CPDLC end response is received.|
