iFly Jets: 747-400 for Flight Simulator 2004 is one of the most advanced simulations ever brought to the FS2004 platform. Working with well known 747 Captains and Engineers, the iFly team captured the "Queen of The Skies" like never before. During development, techniques were implemented in the FS2004 version of this aircraft to closely compare visually and functionally with its FSX counterpart.

High accuracy simulation of cockpit and systems and a full load of features make this a premier expansion to Microsoft Flight Simulator 2004 (FS9). The product was tested by real 747 pilots to help maintain the accuracy required for this simulation.
