资料：Star Airways, Mumbai's dominant airline for the past five years, has reported it is planning to replace its entire aircraft fleet with European-produced Skystream jets. Starting with an initial purchase of 90 jets, Star Airways expects the changeover to take a decade to complete. The new planes will enable the airline to expand its international routes as well as provide replacements for its aging fleet of jet planes. Star Airways and Skystream, in a joint announcement at the Brussels Air Show on Thursday, said that the order included seventeen of the new AWB85O aircraft. This will make Star Airways the first Indian carrier to fly the AWB850, an aim it has had since the powerful jets were first produced.

How long is the change expected to take?
