A program is described in which statistical flight loads and operating practice data for airline transports in current operations are obtained from existing onboard digital flight data recorders. These data, primarily intended for use by manufacturers in updating design criteria, were obtained from narrow-body and wide-body jets. Unique procedures developed for editing and processing the data are discussed and differences from previous NACA/NASA VGH analog data are noted. The program is being expanded to include control surface and ground-operational parameters. Efforts to develop an onboard data processing system to derive direct statistical aircraft operating parameters are reviewed.
