Boeing Next-Generation 737 Carbon Brakes Earn FAA Certification

03 September 2008

Boeing earned certification last week from the U.S. Federal Aviation Administration for its new carbon brakes designed for the Next-Generation 737.

The brakes, supplied by Messier-Bugatti, also entered service last week when Boeing delivered a Next-Generation 737-700 to Delta Air Lines -- the first of 10 737-700s the airline will receive over the next several years.

Carbon brakes weigh 700 pounds (320 kg) less than high-capacity steel brakes for Next-Generation 737-700, -800 and -900ER (Extended Range) airplanes; and 550 pounds (250 kg) less than standard-capacity steel brakes for Next-Generation 737-600s and -700s. Reduced weight contributes to reductions in associated fuel burn and CO2 emissions depending on airline operations.

Delta Air Lines is coupling lighter-weight carbon brakes with drag- and emissions-reducing Blended Winglets (wing tip extensions) to improve operating and fuel efficiency simultaneously on its Next-Generation 737s. Delta's stated goal is to have greater flexibility to serve more markets with existing aircraft, further enhancing the largest international expansion in Delta's history.
