What is required to be carried aboard the aircraft regarding registration?

To operate an aircraft legally, it is mandatory to carry the aircraft's registration certificate aboard. This certificate serves as proof that the aircraft is registered with the relevant aviation authority, such as the Federal Aviation Administration (FAA) in the United States. The registration includes important information about the aircraft, such as its serial number, the name of the registered owner, and the aircraft's registration number.

Having this document readily accessible is crucial, as it may be requested by law enforcement or aviation officials during inspections or in the event of an incident. While other documentation, such as insurance documents and pilot logs, are significant for different reasons, they are not specifically required to be carried on board the aircraft during flight. The need for the registration certificate ensures compliance with regulatory requirements and confirms the aircraft's legitimacy in the airspace system.
