This paper reports on activity log data collected during Boxtop 195. Boxtop aircrew flew a fixed three-shift, three-airplane schedule repeating every 48 hours. A two-page activity log was used to collect data from 41 aircrew and wrist actigraphs were used to provide a second source of information from 18 aircrew. Information was collected on sleep length, hours awake before flying, hours continuously awake, mood, alertness and sleep quality. Significant differences were found between shifts, particularly the night shift which scored lower on mood, sleep quality, and alertness on awakening. Afternoon crews were up longer before flying and at their last touch-down of a work cycle, on average, than morning or night crews.
