Final answer:
The statement is true (option A) because aviation authorities have specific criteria that define which incidents need to be reported, focusing on those that impact safety or indicate potential hazards.
Step-by-step explanation:
The statement 'Some, but not all aviation incidents must be reported' is true. Aviation authorities globally, like the Federal Aviation Administration (FAA) in the United States, have specific criteria set for reporting aviation incidents. The details of what must be reported can be found in legal regulations and guidelines, such as the FAA's Part 830 of the National Transportation Safety Board (NTSB) regulations pertaining to the notification and reporting of aircraft accidents or incidents.
Certain incidents that may pose safety issues or reflect potential hazards are required to be reported so they can be investigated, and measures can be taken to prevent similar occurrences in the future. However, minor events that do not affect safety, typically called 'incidents,' may not always require official reports. Reporting requirements aim to maintain a high level of safety in aviation by ensuring significant events are closely examined.
