The press for eco-efficient air flight is really gearing up. Last week, Virgin Atlantic tested a flight on coconut oil. Now Aero-News Network reports that an Airbus A320 test aircraft has performed the first test flight powered by the International Aero Engines' new SelectOne standard engine. This engine still uses traditional fuel but it is a new version of the V2500 engine that is more fuel-efficient with lower CO2 emissions. The engine will be available for the A319, A320 and A321. The engine will reduce fuel burn by 1 per cent (along with a corresponding reduction in CO2 emissions) and will also improve time-on-wing by 20 per cent and require less maintenance. Unlike other projects, for more fuel-efficient flight, this one will be pressed into service by the end of the year.
