Delta Air Lines To Use Brakes On 737-700s

Boeing announced Monday it earned certification last week from the US 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 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 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.

Carbon brakes are the most recent enhancement that Boeing is offering on its Next-Generation 737. Since its entry into service, Boeing has introduced product enhancements that improve performance, navigation precision and passenger comfort on the Next-Generation 737.
