- 3. Each event desoiption consists of the following:
o the point in the scenario when it is to be initiated o
the malfunction(s) or conditions that are entered to initiate the event o
the symptoms/cues that will be visible to the crew o
the expected operator actions (by shift position) o the event termination point (if applicable)
