If a commercial pilot completed a CAT1 medical exam on February 13, 2001, what is the latest date they can rent an aircraft?

The correct answer is February 28, 2006, because a CAT1 medical certificate for commercial pilots is valid for a maximum of five years if the pilot is under the age of 40 at the time of the examination. If the pilot is 40 years of age or older, the medical certificate is only valid for a maximum of two years.

In this case, assuming the pilot was under 40 on February 13, 2001, the certificate would be valid until February 13, 2006. However, medical certificates must be renewed before they expire in order for the pilot to remain eligible to rent and operate an aircraft. The latest date a pilot can use their medical certificate is the last day of the month in which it expires, thus extending the validity to February 28, 2006. This means that renting an aircraft can occur anytime up until February 28, 2006, using the valid medical certificate issued on February 13, 2001.
