Under what circumstances is the pilot in command required to hold a category and class rating?

The pilot in command is required to hold a category and class rating when carrying another person. This requirement is in place to ensure that the pilot has the necessary training and proficiency to operate the aircraft safely with passengers on board. The category and class ratings indicate that the pilot has successfully demonstrated the skills and knowledge required for the specific type of aircraft they are operating and is thus equipped to handle any emergencies or complications that may arise during flight.

While other scenarios, such as training flights or carrying cargo, have their own regulations, the most stringent requirement is associated with passenger transport. This is due to the increased responsibility and potential risks involved in ensuring the safety of individuals who are not trained pilots. Therefore, when flying with another person onboard, it is critical that the pilot is appropriately rated to ensure the highest safety standards are maintained.
