Define the problem, then upload the three mandatory documents to begin ARP4761 fault tree generation.
Problem Statement (required — defines the top event to analyze)
State the specific hazard/top event and its scope (flight phase, operating conditions,
boundary) you want this fault tree built around. FHA/FMEA/System Design are the data sources —
this is the question you're asking of them. Without it, Claude has to guess which hazard in
your FHA matters most.
