What type of license must a pilot possess to operate a two crew aircraft as pilot in command?

To operate a two-crew aircraft as pilot-in-command, a pilot must possess an Airline Transport Pilot License (ATPL). This requirement is in place because the ATPL is the highest level of pilot certification and encompasses the comprehensive training, experience, and knowledge necessary to command multi-crew aircraft safely.

The ATPL includes extensive knowledge of advanced flight operations, complex navigation systems, and crew resource management, all of which are critical when operating larger aircraft with multiple crew members. It ensures that the pilot is proficient not only in flying the aircraft but also in managing the operational aspects and coordinating effectively with other crew members.

In contrast, a Private Pilot License allows for solo and basic flight operations but is not sufficient for multi-crew operations. A Commercial Pilot License permits pilots to carry passengers and cargo for compensation but still does not entail the full responsibilities and training required for being pilot-in-command of a two-crew aircraft. A Flight Instructor License is focused on teaching flying skills to students and does not grant authority for command in multi-crew situations. Thus, without an ATPL, a pilot would not meet the regulatory requirements to serve as pilot-in-command in such a complex operational environment.
