UPS has added winglets to its Boeing 767 fleet in order to save fuel and reduce emissions.
The wingtip devices are arrow-shaped surfaces attached to the tip of each wing. Each winglet is 11 feet tall, and the modifications will add about five and a half feet of span to each wing.
They will enhance the overall efficiency of the aircraft, save fuel by reducing drag and lower noise emissions by improving takeoff performance, the logistics company said in a written statement.
UPS currently operates 54 of the 767 aircraft, with five on order. The company plans to have winglets on all 767 aircraft by the end of 2014. Winglets are already installed on UPS's 747 and MD-11 fleets, and the A300-600 has a similar device called a wingtip fence.
