What must you possess to exercise the privileges of your airman certificate?

To exercise the privileges of your airman certificate, it is essential to possess a medical certificate and a logbook with endorsements. The medical certificate is required to ensure that you meet the necessary health and physical standards for piloting an aircraft, which is critical for both your safety and that of others. Additionally, having a logbook with endorsements is important because it provides proof that you have received the necessary training and qualifications for the specific operations you are intending to undertake. This logbook serves as a record of flight experience, training, and endorsements from authorized instructors, which are mandatory for legally performing specific flight actions.

In contrast, while aircraft insurance, passenger lists, flight plans, and maintenance logs are important for operational compliance and safety, they do not directly pertain to the legal requirements for exercising the privileges of your airman certificate. Thus, possessing a medical certificate and a properly endorsed logbook is the correct requirement for a pilot to exercise their flying privileges.
