15 Appendix

A sample Score Sheet is attached. Human recorders were asked to capture pertinent data for each flight in addition to the data captured in the log files. On the front page, we recorded the team name, test number, flight times, and battery percentages, etc. On the back, we detailed any out-of-the-ordinary events. In this example from Test 3A, the pilots reported the pre-programmed software was not flying at the Above Ground Level (AGL) altitude that had been programmed. This turned out to be a failure of the Air Boss to understand how Dronelink executed the program when a specific AGL was specified at the landing site. An explanation of this situation is described in detail on page 44. About 25% of the recommendations from pilots were taken from the “hot wash” debrief topics captured on the backside of these Score Sheets.
