What is the minimum requirement for logging flight time in an aircraft that requires two pilots?

The minimum requirement for logging flight time in an aircraft that requires two pilots is that a pilot must log time while occupying a crewmember station if qualified. This means that even if a pilot is not acting as the pilot in command, as long as they are appropriately qualified and seated in a position designated for the operation of the aircraft, they can log flight time.

In the context of two-pilot operations, this provision acknowledges the vital role of both pilots in the safe and effective handling of the aircraft, allowing both to gain valuable experience and hours that contribute to their overall competency and credentials. It also reflects the understanding that modern aviation often involves teamwork in cockpit operations, hence recognizing the contributions of both pilots.

Other options revolve around specific requirements that do not align with the regulations or practical experiences in two-pilot operations, such as sole manipulation of controls or needing supervision from an instructor, which are not primary factors in logging time while fulfilling a role within a crew.
