What should a pilot do to transfer control of the aircraft between crewmembers?

The correct approach to transferring control of the aircraft between crewmembers is to execute a formal announcement over the intercom. This method is crucial in ensuring clear and unambiguous communication about who is in control at any given time. Establishing a formal announcement helps prevent any misunderstandings that could arise from less formal methods of transfer.

Visual confirmation through a head nod might imply a mutual understanding between crewmembers, but it lacks the clarity needed in a potentially high-stress environment where verbal communication can significantly reduce risks. Pumping the rudder pedals could potentially confuse the other pilot and is not an industry-recognized method to signify a transfer of control. Guiding the aircraft towards a designated landing area does not directly relate to control transfer—it focuses on aircraft operation rather than the communication necessary for a safe transfer process. Therefore, the emphasis on a formal intercom announcement establishes a standard operating procedure that enhances safety and coordination in the cockpit.
