 Boeing has announced that it 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 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.
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.
