Which party has the defined authority to oversee aircraft movement after an accident?

The authority to oversee aircraft movement after an accident falls under the purview of the Minister. Following an aircraft accident, it's vital to ensure safety and proper investigation procedures are adhered to. The Minister's role includes responsibility for establishing and enforcing regulations concerning aviation safety, which encompasses the authority to oversee the situation post-accident.

This responsibility is crucial as it helps to establish a clear chain of command and accountability in the investigation process, enabling effective action to be taken to prevent future accidents. The Minister's involvement ensures that all activities following an accident align with national safety standards and regulatory frameworks.

The other parties, while they may play roles in the immediate response or ongoing operations, do not hold the defined authority to oversee aircraft movement in the context of an accident. For instance, the airline operator would focus on their operational aspects, and the pilot in command has authority over flight operations but not the broader regulatory oversight needed in the aftermath of an accident. The Transportation Safety Board (TSB) is tasked with conducting investigations but does not have authority over aircraft movement. Thus, the Minister is the correct choice for overseeing aircraft movement post-accident.
