Compliance: the tracking software of the activity of the pilots complies with the LIL (except for a few minor failures reported): fair collection of data (information of person concerned about the existence of the treatment, its purposes, the recipients and their rights by means of a paper memo and on the dedicated intranet), no diversion of the final purpose of the processing (the data contained in this software are not crossed with those taken into account for the monitoring or the pilots career).
Nature of the data: information about sick leaves are not sensitive data because the reason of the leave is not indicated, and therefore is not data on the health.
