Which of the following is a requirement for obtaining a Remote Pilot Certificate?

To obtain a Remote Pilot Certificate, one of the key requirements is passing the FAA UAS knowledge test. This test evaluates a candidate's understanding of various important topics related to unmanned aircraft systems, including regulations, airspace classifications, weather effects, and emergency procedures. Successfully passing this exam ensures that the pilot has the necessary theoretical knowledge to operate a UAS safely and legally.

The other options present activities that may be beneficial for pilots but are not required by the FAA for certification. For instance, completing a specific flight training course might enhance a pilot's skills but is not mandated. Similarly, while demonstrating flight proficiency with a licensed instructor could be a good practice for inexperienced pilots, it is not a formal requirement for obtaining the Remote Pilot Certificate. Lastly, submitting a medical examination report is typically not necessary for most remote pilots, contrasting with traditional pilot requirements where a medical certificate is needed. Therefore, passing the FAA UAS knowledge test remains the definitive requirement to achieve certification.
