Airbus A320neo

What makes the A320neo stand out are the new engines and improved aerodynamics. The addition of "neo" stands for "New Engine Option". The aircraft is 15 percent more fuel efficient than today's comparable models. It also shows impressive figures in terms of noise reduction: the 85 decibel maximum noise-level contour of a starting A320neo is around 50 per cent lower than that of the current A320. In accordance with certification standards, the cumulative noise emissions are about 29.8 dB below the applicable ICAO limits, which represents a significant advance in terms of noise and emissions reduction compared to the current fleet.
