The Evolution of Cockpit Culture
From autocratic captains to coordinated flight crews
In early commercial aviation, captains wielded unquestioned authority. The tragic 1977 Tenerife collision and 1978 United 173 fuel starvation disaster catalyzed NASA and United Airlines to pioneer Crew Resource Management (CRM).
Today, every crew member — from the junior First Officer to senior check captains — is trained and empowered to voice safety challenges using assertive, non-punitive standardized language.
The Sterile Cockpit Rule (FAR 121.542)Aviation Regulation
"No flight crewmember may engage in any non-essential activity or conversation during a critical phase of flight — including all taxi, takeoff, landing, and all flight operations below 10,000 feet."
