Real range benefit B767-300 ER with Winglets
Hi everybody,
I was wondering according to your experiences what is the real gain of range between a B767-300ER and a B767-300ERW (equiped with winglets) at MTOW and same meteorological conditions.
I see from APB to various press articles numbers from 5% to 19% in terms of fuel savings so I'm curious to see the results in terms of range in reality.
Thanks for your feedbacks
