Microsoft Flight Simulator X is a gaming software that lets you experience realistic, interactive aircraft missions. It is the tenth version of the flight simulator program that runs on Windows platform. Free Flight lets you travel from the airport in your hometown to any place. Dynamic Living World features a world of motion with airport vehicles, wild animals, livestock, air traffic, ships and boats on lakes and oceans and auto traffic on highways. New Aircraft lets you choose from 21 legacy and new aircrafts. Shared Skies lets you can choose missions and airports, act as air traffic controller, create your own team, and play online with chat using your headset. BGL [Flight Simulator Scenery File] is a game file that contains data of a scenery for an airport or flight location in Microsoft Flight Simulator. Small locations require single BGL format, while big airports or complex locations require multiple BGL. BGL files that are inclusive with Flight Simulator should not be edited. But you can create BGL files using third-party application such as FSX Planner to customize your locations. You can save it in the Addon Scenery directory or in the Custom directory within Flight Simulator’s main folder.
