AvAero of Safety Harbor, Fla., announced that Falconbridge Mining is the first customer for the FuelMizer aerodynamic modification of the Boeing 737-200/300. AvAero, which received FAA approval in April last year, EASA certification in August last year and Transport Canada approval last month, claims the FuelMizer will decrease the twinjet’s fuel burn by an average of 4 percent. AvAero said that repositioning the trailing-edge flaps (kit price $120,000) increases aft wing camber, which lets the airfoil generate the same degree of lift at a lower angle of attack.
