Owners, or potential owners, of the Hawker 800A’s and 800XP’s currently have the option of adding blended winglets to their private jet. This upgrade has been available since late 2004, during which more than 65 Hawkers have been modified. Many ultra-long-range and commercial jets now come standard with winglets -- but what exactly are the benefits of adding blended winglets to a private jet?
The main function of blended winglets is to reduce drag. Admittedly, drag reduction is probably not foremost on the minds of private jet owners, but it is an extremely important point. Reducing drag increases speed and decreases fuel consumption, thereby extending range and saving money.
Although the winglets cut operating costs, some owners shy away from the modification because of the initial expense of adding the winglets: the process takes three weeks and costs $438,000. The winglets improve the performance of the private jet and cut down on operating costs, which saves money – but how much money would really be saved by adding the winglets?
To begin with, Hawker 800’s with blended winglets burn on average 7% less fuel than their straight-wing counterparts. The Hawker 800 without winglets burns about 250 gallons per hour. With winglets, the Hawker 800 would consume only 232.5 gallons per hour, saving 17.5 gallons for each hour of flight time. Fuel currently costs $3.80 per gallon, which works out to a savings of $66.50 saved for every hour in the air. At this rate, it would take 6,628 hours of flight time to match the cost of adding the winglets.
