Sharklets & Scimitars

摘要

The financial challenges faced by airlines in recent years due to the combination of rising fuel prices and choppy travel demand have made efficiency the industry's watchword. That's partly why Airbus and Boeing launched the A320neo and 737 MAX, their respective upgrades of their respective twin-jets equipped with new engine and airfrarne technologies. But airlines want cost savings in their aircraft of today as well those arriving tomorrow and that's led to the manufacturers investing in efficiency improvements for the A320ceo (current engine option) and 737NG, rather than putting them out to grass as the new generation arrives.
