COMMERCIAL DELIVERY OF IL-78 AIRCRAFT
Refueling process is monitored by operator, occupying gunner's position of the Il-76. His workplace is equipped with optical rear view system, in addition to radio-technical and light signal equipment. Once connected, refueled aircraft can receive up to 57720kg of fuel from the wing tanks (85720kg from both wing and fuselage tanks) at rate 900 to 2200l/min. While early production Il-78 had removable fuselage tanks and could be used as a military transport, later improved version Il-78M can not be converted to transport.
