A second-class medical certificate issued to a commercial pilot allows the pilot to exercise which privileges?

The correct answer indicates that a second-class medical certificate issued to a commercial pilot allows them to exercise commercial pilot privileges until April 30 of the following year. In the context of aviation, a second-class medical certificate is specifically designed for commercial pilots and is valid for a defined period. The validity period can differ based on the pilot's age and specific regulations, but for a second-class certificate, it generally allows commercial pilots to operate under the privileges granted by a commercial license for one year.

This option accurately reflects the typical expiration timeline associated with a second-class medical certificate. Understanding the duration of medical certificates is crucial for pilots, as it directly impacts their ability to legally operate aircraft for commercial purposes.
