Improved Takeoff Performance
By allowing a steeper climb, winglets pay off in better takeoff performance, especially from obstacle-limited, high, hot, weight-limited, and/or noise-restricted airports. Performance Improved climb gradients increase 737-800 allowable takeoff weight (TOW).
Some examples include:
- Chicago-Midway: ~1,600 lb additional TOW
- Lanzarote (Canary Islands): ~3,500 lb additional TOW
- Albuquerque, Denver, and Salt Lake City: ~4,400 lb additional TOW
Winglets Provide Additional Performance at Difficult Airports
