Who designates an individual as qualified to be a plane captain in writing?

The authority to designate an individual as qualified to be a plane captain in writing rests with the Commanding Officer or Officer in Charge (OIC). This designation is significant because it represents an official recognition of the individual's readiness and capability to perform the responsibilities associated with the role of a plane captain, which includes overseeing the care and maintenance of the aircraft, ensuring operational readiness, and adhering to safety protocols.

The Commanding Officer or OIC is ultimately responsible for the overall readiness of the aircraft and personnel within their command; therefore, their written approval carries substantial weight and signifies the trust placed in the designated individual’s skills and judgment. This process ensures that only those who have met the necessary training, experience, and evaluation standards are assigned to such critical roles, thus maintaining the safety and effectiveness of flight operations.
