What authority does the Pilot in Command (PIC) have regarding intoxicated passengers?

The correct answer highlights that the Pilot in Command (PIC) has the authority to refuse boarding or remove intoxicated passengers from the aircraft. This is grounded in safety regulations and the overall responsibility of the PIC to ensure the safety of everyone on board. The PIC is ultimately responsible for the operation of the aircraft and must make decisions that protect the integrity of the flight and the well-being of all passengers.

Allowing intoxicated individuals to board poses significant risks, as their ability to follow safety instructions and act responsibly during the flight could be compromised. By exercising the authority to refuse boarding or manage intoxicated passengers, the PIC is upholding safety standards and regulations that safeguard the flight environment. This decision aligns with the legal responsibilities under aviation laws, which prioritize safety above all else during a flight.

Contextually, the other choices do not align with the responsibilities and authority granted to a PIC. Allowing intoxicated passengers to board would not only violate safety protocols but also legally jeopardize the flight. Warnings alone would not address the potential hazards presented by intoxication, while providing assistance does not address the critical responsibility of ensuring that impaired individuals are not allowed to influence the flight's safety.
