Boeing gets FAA ok for fuel-saving airplane brakes
Boeing today said that its new carbon brakes designed for the next-generation 737 received certification last week from the U.S. Federal Aviation Administration last week. The brakes, supplied by Messier-Bugatti, entered service last week when Boeing delivered a next-generation 737-700 to Delta Air Lines.
Boeing says the carbon brakes weigh 700 pounds (320 kg) less than high-capacity steel brakes on 737-700, -800 and -900ER airplanes; and 550 pounds (250 kg) less than standard-capacity steel brakes for 737-600s and -700s. Boeing claims that the reduced weight contributes to reductions in associated fuel burn and CO2 emissions depending on airline operations.
