777-300ER – Then and Now

I’ve been working on two new features for the pre-Farnborough issue of Flight, one on 777 and the other on the 747-8. While researching yesterday, I came across a very interesting fact. With the help of the Way Back Machine, the historical archive of the entire internet, I found that the range of the 777-300ER has increased almost 11% (7,175 nm to 7,930 nm) since 2001! The maximum takeoff weight increased 25,000 lbs in that same time as well without a change in fuel capacity. To boot, the 777-200LR had a 6% increase in range too.

See for yourself.

    Is this marketing spin or does this reflect real-world use? Everything’s improved, but nothing on the aircraft has changed. And could they be holding back on actual 787 performance?

    Underpromise but overdeliver perhaps…

    Well not only where the perfomrnace estimates in 2001 conservative but in the years since the 777-300ERs entry into service Boeing and GE have been consistently adding improvements to the airplane to lighten the aircraft and to improve fuel efficency and range.

    As for the 787, I think we’ll know by late 2009 or early 2010 how it does in real world use vs estimates.
