This Airbus A320 aircraft flew last month with a new addition. While the aircraft might not look too different from an ordinary A320 at first glance, the observant among you will notice the presence of winglets on this narrowbody jet. A320′s normally have small ‘wingtip fences’, but the winglets on this testbed aircraft are a lot larger and will potentially save even more fuel (and therefore emissions) by improving the aerodynamics of the wing. The trials of these blended wingletson the A320, produced by Aviation Partners, are expected to take around three months.
