What is required for a recreational or private pilot acting as pilot in command to have while aboard the aircraft?

A recreational or private pilot acting as pilot in command must possess a medical certificate if required and hold an appropriate pilot certificate. This requirement ensures that the pilot is medically fit to operate an aircraft, which is crucial for the safety of both the pilot and any passengers on board. The appropriate pilot certificate verifies that the pilot has met the necessary training and competency standards set forth by aviation regulations, thus confirming their ability to safely navigate and control the aircraft.

While a current logbook endorsement regarding a flight review or proof of insurance may be important for various situations, they are not specifically mandated for a pilot in command to carry while on board the aircraft. The emphasis on having both the medical certificate and the appropriate pilot certificate ensures compliance with safety regulations and operational requirements within the aviation industry. This dual requirement underscores the importance of both health and certification in maintaining aviation safety standards.
