Sensemaking in Safety Critical and Complex Situations
from the mishap report. For the accuracy of this study, it is imperative that someone
with knowledge of the Predator UAS GCS be able to answer questions related to the
usage/ layout of IO devices listed in mishap report. Therefore, a volunteer Predator
operator was enlisted. He agreed to review the IO-related mishap report data and
answer questions via email or teleconference. F igure 13.11 describes the phase III
process flow chart for the application of sensemaking data/ frame model and ANSI/ -
HFES-100 standard to evaluate the HF/ E portion of the AIB report:
Once the IO-related information from AIB report was transcribed into 20 segmented chunks of data ( SCD), where each segment represented a single idea, the
