Why should pilots be silent when landing?
According to The Sun, pilots during the critical phases of flight - takeoff, landing - must refrain from many actions that can disrupt the control of the aircraft. That is why, for example, they make announcements for passengers half an hour before boarding.
Pilots are required to comply with the "sterile cockpit" (or sterile cockpit) rule, a civil aviation rule that prohibits them from being distracted by unnecessary activities during certain phases of flight.
For example, they are prohibited from talking about abstract topics, eating or listening to music during landing, takeoff or any other operation that is performed at altitudes below 10,000 feet (3,048 meters). That is why pilots make announcements for passengers 20-30 minutes before landing.
The sterile cockpit rule was introduced after several fatal accidents due to poor cockpit discipline. An investigation into the incidents revealed that pilots were distracted from their duties during the landing process.
The same rule applies to flight attendants. During a sterile cockpit, the crew shall not communicate with the pilots, except in cases of extreme necessity. Flight attendants are busy preparing passengers for takeoff or landing.
