STERILE COCKPIT RULE

The Sterile Cockpit Rule is a regulation requiring pilots to refrain from non-essential activities during critical phases of flight, normally below 10,000 feet. The FAA imposed the rule in 1981( and adopted by most regulatory bodies) after reviewing a series of accidents that were caused by flight crews who were distracted from their flying duties by engaging in non-essential conversations and activities during critical parts of the flight. One such notable accident was Eastern Air Lines Flight 212, which crashed just short of the runway at Charlotte/Douglas International Airport in 1974 while conducting an instrument approach in dense fog. The National Transportation Safety Board (NTSB) concluded that a probable cause of the accident was distraction due to idle chatter among the flight crew during the approach phase of the flight.
