Winglets.
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).
Better climb performance also allows lower thrust settings, thus extending engine life and reducing maintenance costs. Lower Required Thrust Levels Extend On-Wing Life.
Takeoff - Winglets allow up to 3% incremental derate.
Cruise - Reduced cruise thrust. Cruise fuel flow is reduced by up to 6% giving savings in fuel costs and increasing range.
INCREASED PAYLOAD RANGE
The addition of Aviation Partners Blended Winglets to Ryanair's 737-800 has demonstrated drag reduction in the 5 to 7% range that measurably increases range and fuel efficiency . In addition, the Blended Winglets allow the 737-800to take off from higher, hotter airports with increased payload.
ENVIRONMENTALLY FRIENDLY
Winglets enhance performance at noise-restricted airports and cut the affected area by 6.5 percent, saving money on airport noise quotas or fines. By reducing fuel consumption, winglets help lower NOx emissions by 5%.
IMPROVED OPERATIONAL FLEXIBILITY
By increasing Payload Range and Overall Performance, Blended Winglets add flexibility to fleet operations and route selection. Helps avoid step climb. With Blended Winglets, can (depending on aircraft wight) climb direct to 41,000 feet where traffic congestion is much less and we can take advantage of direct routings and shortcuts.
