Next-Generation 737 Production Winglets
Benefits
Depending on the airplane, its cargo, the airline's routes and other factors, winglets have the potential to:
- Lower operating costs by reducing block fuel burn by 3.5 to 4.0 percent on missions greater than 1,000 nautical miles
- Reduce engine maintenance costs
- Increase range up to 130 nautical miles
- Improve payload capability by up to 6,000 pounds (.5 to 3 metric tons)
- Improve takeoff performance and obstacle clearance
- Increase optimum cruise altitude capability
- Reduce community noise by .5 to .7 EPNdB (Effective Perceived Noise Level in Decibels) on takeoff and slight improvement on approach
- Lower emissions through lower cruise thrust
