One Million Dollars Per Year

The title sums up the results of the performance improvements being introduced on new 747-8s. One million in fuel costs saved per frame, per year. The improvements itemized:

• 7,700 lbs removed
• 1.8% fuel burn reduction in the engines
• Tail tank enabled, with software modification to keep fuel in the tail to reduce the need for trim.
• FMC improvements, including RNP AR and improved climb functions
• 3.5% fuel burn improvement overall

These improvements will all be delivering this year. Boeing plans on continuing to improve the performance of the 747-8 as well. In a few more years it might actually take off with empty tanks and land twelve hours later with them overflowing.

In other rumors, Cathay's 14th frame has shown up on the charts, although it has yet to be ordered. Another interesting thing is line 1435 (RC021), the current test frame for the above improvements and former Lufthansa D-ABYE, is once again listed internally as earmarked for Lufthansa. This could be a clerical error, but I'm hopeful Lufthansa has had a change of heart.
