Which of the following is NOT a requirement for obtaining a pilot certificate?

To obtain a pilot certificate, there are several essential requirements that a candidate must fulfill. Among these, medical certification is indeed a necessity to ensure that the pilot meets the required health standards. However, the question asks which option is NOT a requirement.

Reading proficiency in English is crucial, as pilots must be able to understand and communicate effectively with air traffic control and other personnel. A logbook endorsement from a Certified Flight Instructor (CFI) is required to validate that the student has received proper training and is competent in the necessary skills. Completion of a knowledge exam is also mandated to assess the applicant's understanding of aviation principles, regulations, and safety practices.

Given this context, medical certification remains a vital component of the certification process, thereby clarifying that it is indeed a requirement, contrary to what the selected answer suggests.
