What must crew members do during the sterile cockpit phase?

During the sterile cockpit phase, it is essential for crew members to avoid any non-essential communication. This critical period typically occurs during the takeoff and landing phases of flight, when the pilots need to focus entirely on the operation of the aircraft without distractions.

The sterile cockpit rule is in place to enhance safety, as it allows the flight crew to concentrate on task management and situational awareness. Minimizing extraneous communication helps reduce the likelihood of errors that could arise from distractions. This means that light conversations with passengers, completion of non-essential paperwork, or providing updates that might divert attention away from aircraft operations are not permissible during this time.

Overall, adhering to the sterile cockpit protocol is vital for maintaining the highest safety standards in aviation, especially during the most critical phases of flight when operational focus is paramount.
