Which of the following is NOT included in the Canadian Aviation Regulations?

The Canadian Aviation Regulations (CARs) encompass a range of rules and standards designed to ensure aviation safety and efficiency within Canada. This includes areas such as air safety protocols, which outline safety measures and operational procedures for aircraft operations, and guidelines for pilot training that specify the requirements and standards for training and certification of pilots.

Passenger boarding procedures, while they may seem operational and somewhat logistical, still fall within the domain of aviation operations and safety protocols that the CARs govern. These procedures are essential for ensuring the safety and security of passengers during the boarding process.

On the other hand, hotel booking regulations are not part of the Canadian Aviation Regulations. These regulations pertain to the hospitality industry rather than aviation. As such, they do not relate to the operational, safety, or training aspects overseen by the CARs. Therefore, hotel booking regulations are correctly identified as not included in the Canadian Aviation Regulations.
