Several airlines have recently been introducing software and tools produced by commercial third parties that enable flight crews to assess their own performance after every flight, based on FDM-derived data. There are differences in the way each of these tools work, how the flight is displayed (graphics, animations, etc.), and how data is transmitted to individual pilots and on which support (smart phone, tablet, PC, etc.), but the general idea conveyed by airlines is that such systems enable flight crews to review their last flight and identify possible areas of improvement.
