Boeing 737 max will be 4% more fuel efficient than Airbus rival
Boeing Co.'s 737 Max, a single- aisle plane that will offer new engines will be 4 percent more fuel efficient than Airbus's A320neo rival offering, even with smaller fan diameters on its engines, commercial plane market head Randy Tinseth said today.
Engines and fan-diameter is only one element in three that determine efficiency, Tinseth said. Aerodynamics and weight are also factors, he said, and Boeing plans to optimize weight and work on aerodynamic performance. He spoke at a conference sponsored by ISTAT, an aircraft traders' industry group.
