"With this improvement, 747-8 customers will use roughly 30 fewer trucks of fuel per airplane per year."
Boeing Test & Evaluation teams validated that the engine improves the airplane's efficiency by 1.8 percent.
"With this improvement, 747-8 customers will use roughly 30 fewer trucks of fuel per airplane per year," said Eric Lindblad, vice president and general manager, 747-8 program.
All three PIP components can be retrofitted on the 747-8. The tail fuel reactivation is applicable only for the 747-8 Intercontinental, and the Flight Management Computer upgrades also can be made to 747-400.
