When must commercial pilots have their pilot certificates accessible?

Commercial pilots are required to have their pilot certificates accessible when acting as pilot in command. This regulation is in place to ensure that the pilot operating the aircraft has the appropriate qualifications and authority to conduct the flight safely. Being pilot in command comes with significant responsibilities, including the safety of the aircraft and all on board, so having the certification readily available is a vital practice for accountability and compliance with aviation regulations.

In various situations, such as carrying passengers or flying solo, the pilot's certification must indeed be verified; however, the regulation specifically mandates that the certificate must be within reach or accessible at all times when the pilot is in command of the aircraft. This practice reinforces the importance of maintaining proper documentation during flight operations and helps ensure safety in aviation.
