What does the Tokyo Convention authorize the aircraft captain to do?

The Tokyo Convention, formally known as the Convention on Offences and Certain Other Acts Committed on Board Aircraft, grants the aircraft captain specific authority to ensure the safety and security of the flight. Among these powers is the ability to impose reasonable measures, including the restraint of disruptive passengers. This is crucial for maintaining order and the safety of all individuals on board the aircraft.

The rationale behind this authority stems from the need for immediate action in circumstances where a passenger's behavior may jeopardize safety. Restraint measures can prevent further escalation of a situation and allow the crew to manage the incident effectively.

Although the other choices represent actions that could be taken in specific scenarios, they do not specifically highlight the captain's authority under the Tokyo Convention as directly as the ability to impose reasonable measures, including restraint. Conducting emergency landings, diverting the flight route, or requesting additional security personnel might be part of a captain's broader responsibilities but are not explicitly authorized by the Tokyo Convention in the same manner as the ability to impose restraint.
