It is pretty common these days to see commercial aircrafts fitted with regular blended winglets. They greatly improve the aerodynamics of the aircraft and resultantly the fuel consumption is also reduced. However, the latest Split Scimitar Winglets are a notch above these. Unlike the marginal reduction in fuel consumption, these winglets help in reducing the total fuel consumption by as much as 2%, which adds up to a significant amount.
Now United Airline is planning on equipping all its 737, 757 & 767 aircraft with these new winglets. The projection is that the company will save over 65M gallons of fuel on an annual basis. This equals over 645,000 metric tons of CO2 & 200M / year just in jet fuel costs. Apart from United Airline, Southwest Airline has also announced that they have begun using the Split Scimitar Winglets on their 737-800’s. Southwestern Airline have completed fitting these incredible winglets on 52 existing planes and had previously installed them on 33 new airplanes.
