While recent changes to Federal Aviation Administration laws meant airline passengers could use their personal electronic devices more freely during all phases of a flight, its done just the opposite within the cockpit. A new rule that goes into effect two months from now means pilots can no longer use electronics devices like cell phones, tablets, or computers for personal use, reports The Wall Street Journal. The new rule is an expansion of one enacted in 1981, known as the sterile cockpit, designed to keep the environment on the flight deck was free from potentially dangerous distractions. Prior to todays changes, personal use of devices was still considered covered under that rule, but not when aircraft went above 10,000 feet. The FAA notes that several incidents led Congress to push it to update the sterile cockpit rule.
