A Mandatory Occurrence Report must be made for any occurrence involving air traffic services for which the collection of associated safety related data and conditions is mandatory.

• A. Safety Occurrence Report
• B. Mandatory Occurrence Report
• C. Operational Event Log
• D. Incident Report

Answer: (B)

When an event occurs in air traffic services and regulations require collecting specific safety-related data and conditions, the formal process is to file a Mandatory Occurrence Report. This designation signals that reporting is not optional; it ensures standardized data is gathered and sent to the appropriate authority for safety analysis and oversight. The other terms describe different kinds of reporting or records: a Safety Occurrence Report may cover safety issues but isn’t necessarily tied to mandated data collection; an Incident Report is a general term for events without implying regulatory data requirements; an Operational Event Log is usually an internal record of operations rather than a formal regulatory report.
