he system has two displays controlled by a real-time expert system,i.e.,one for conditions and procedures and the other for various messages.Two pilots participated in flight simulator tests in which various emergency situations were encounterd.Results indicate that the system 1)remarkably reduced pilot workload,2)enhanced crew coordination and situation awareness due to looking at color graphic displays instead of reading written checklists,3)created a different cockpit environment since reading checklists is not necessary,and 4)is especially useful for pilot training.
