An Avianca LB-11 at New York City International Airport.
The Long Beach AF LB-11 is a three-engine medium- to long-range wide-body jet airliner, manufactured by Long Beach Aircraft Factory. Based on the LB-10, it features a stretched fuselage, increased wingspan with winglets, refined airfoils on the wing and smaller tailplane, new engines and increased use of composite materials. Two of its engines are mounted on underwing pylons and a third engine at the base of the vertical stabilizer. It also features an all-digital glass cockpit that decreases the flight deck crew from the three required on the LB-10 to two by eliminating the need for a flight engineer.
