Microsoft Flight Simulator (v4.0)

Microsoft Flight Simulator (v4.0) program was designed to give users a real-life flying experience through simulation. This simulator was released for Microsoft DOS. Microsoft Flight Simulator (v4.0) was developed by Bruce Artwick Organization Ltd.
This version was released in 1989, just 15 months after the release of the 3rd version of the simulator. The previous was rather criticized for its “flying on rails” feeling experienced by the users. This version brought several changes from the previous Microsoft Flight Simulator (v4.0).
The new improvement included new and improved aircraft Models and also an upgraded version model of Cessna Skylane. The Previous version included 5 cities of the United States of America and in this version too, these cities are included. These cities are San Francisco, New York, Seattle, Los Angeles and Chicago. The Version 4 became successful due to the addition of Aircraft and scenery Design (ASD). This feature helped the users to build from within the program. Custom scenery units were also available which were known as SC1. These custom sceneries could be exchanged with other users.
Another addition in the Microsoft Flight Simulator (v4.0) was the Aircraft Adventure Factory (AAF) which included two main features. The first being the Aircraft Factory, which was a windows based program which allowed custom design aircraft shapes. It is to be used in the Microsoft Flight Simulator (v4.0) as an easy to use CAD interface.
The second component of the AAF was the adventure module. It used a basic language, similar to QBASIC. A user had the option to build and run a script from within the program. Aircraft position, airspeed, altitude could be accessed as an F4 parameter.
The Microsoft Flight Simulator (v4.0) was considered to be one of the best versions of the whole Microsoft Flight Simulator versions.
