Microsoft Flight Simulator X

&nbsp

Microsoft Flight Simulator X, also known as FSX, is the latest version of Microsoft Flight Simulator after Flight Simulator 2004. It includes a graphics engine upgrade as well as compatibility with Windows Vista, having been marketed by Microsoft as the most important technological milestone in the series to date. It is the first version in the flight simulator series to be released on DVD-ROM.

Overview
Flight Simulator X marks the tenth version of the popular line of flight simulators. It was officially released to the US market on October 17, 2006. According to Microsoft's Web site for the game, a standard edition features everything from navaids to GPS and airways. It also includes 18 planes, 28 detailed cities, and 40 airports with a deluxe version featuring 24 aircraft, and 38 cities. Flight Simulator X was officially unveiled at the 2006 International Consumer Electronics Show (CES) as a gaming showcase for Microsoft Windows Vista and is now also compatible with Windows 7. Microsoft released screenshots as well as a list of frequently asked questions as a press release on Microsoft Flight Simulator Insider, and numerous flight simulator communities. This also included mission-based gameplay with mission specific aircraft as well as an upgraded rendering engine capable of increased detail. Following the Electronic Entertainment Expo (E3) in May 2006, Microsoft published new screenshots, videos and an official trailer. The overall reaction by the community was quite positive, and the graphical quality of the simulator has greatly increased. Flight Simulator X has a required system rating of 3 for Windows Vista and a recommended rating of 5.

Sequel
On 22 January 2009, it was reported that development team behind the product was being heavily affected by Microsoft's ongoing job cuts, with indications that the entire Flight Simulator team would be laid off. The news was later confirmed by Microsoft officials stating they were committed to the Flight Simulator franchise, with expectations to continue product releases in the series, but had nothing specific to announce at that time. On 17 August 2010, Microsoft announced Microsoft Flight, a new simulation game that boasts a further improved graphics engine, and enhanced simulation features.

Standard vs. Deluxe Edition
Flight Simulator X was released in three editions, Standard, Deluxe and later Gold. The Deluxe Edition incorporates some additional features, including an on-disc Software Development Kit (SDK), three airplanes with the Garmin G1000 Flight Deck, and the ability for the player to act as Air Traffic Control (ATC) for other online users with a radar screen. The Deluxe Edition features 24 aircraft compared to 18 in the Standard Edition, 45 high-detail airports compared to 40, 38 high-detail cities compared to 28, and 51 structured missions compared to 30+. Microsoft Flight Simulator X: Gold Edition combines the Deluxe Edition and the Acceleration expansion pack into one.

New features
The new features in Flight Simulator X include:
 * Improved graphics including enhanced texture resolution, new Earth model facilitating polar flights, true road data, region-specific textures, minimal 3D animals, star constellations, etc. Also, the scenery textures now line up with the automatically generated (Autogen) buildings. Maximum rendering-engine-supported scenery resolution of 7 cm/pixel (not available with default scenery).
 * Airports now have jetways that move to the aircraft by the key combination Ctrl + J. (happens for AI aircraft automatically) Airport Vehicles also drive around the airport to you and AI aircraft. (Baggage cars, pushtrucks, fuel trucks, etc.) (International airports only)
 * The built-in GPS support has been upgraded to include Garmin G1000 integrated glass cockpit, (select aircraft in the Deluxe version only).
 * Improved ATC featuring certain non-FAA procedures where appropriate (for example, altimeter/QNH scale in metric units) and numerous minor updates such as an improved progressive-taxi feature.
 * Improved and new default aircraft including, for example, an Airbus A321. Default aircraft systems modeling is rather extensively improved, featuring, for example, APU, fire protection, passenger advisory sign switches etc.
 * Improved weather system, including better visibility modeling.
 * Revamped multiplayer functionality featuring Shared Skies, a feature allowing multiple users to share the same cockpit.
 * Tower Controller, a feature in the Deluxe version allowing users to simulate local control at many airports worldwide during multiplayer gaming.
 * Revamped sound system with support for 5.1 surround sound.


 * Proprietary SimConnectAPI to allow FSUIPC-like access to Flight Simulator functions and variables.
 * Mission engine allowing creation of dynamic missions with developer control of many simulation variables, sound file playback, AI aircraft traffic etc. in relation to what the user is doing — essentially an evolution over the APL and ABL adventure programming languages featured in previous versions of the software. Dozens of missions ship with the product.
 * Most of the vintage aircraft that were a key theme in the previous version have been dropped, with the exception of the DC-3 and Piper J-3. Both aircraft are featured in the default missions that ship with the product.
 * The maximum altitude in the game has been increased to 100,000,000 ft. Therefore, FSX maximum altitude is approximately 2.39 times the diameter of the Earth at the equator.
 * Camera shake in the virtual cockpit as the aircraft banks, accelerates, brakes, flies through turbulence etc.
 * Realistic flexible wings in some commercial airplanes: the wings flex while going through turbulence, increasing rate of ascent or descending, undergoing major plane movements, flaps being fully extended, general vibrations to the plane, etc.  An example of an aircraft with this wing movement is the Boeing 747-400.
 * New water effect which has 3D waves with curled up object refraction according to the wave movements and with sunshine reflection.
 * Ability to easily take a screenshot while in the game. Pressing the "V" key takes a picture of the game and saves it as a .bmp image in the "My Pictures" folder.
 * Aircraft can cast shadows on themselves.
 * Aircraft interiors and exteriors use different files. This allows an advanced user to take one exterior model of an Airbus A320 and merge it with an interior made by someone else.
 * Red Bull Air Race World Championship racing.

Aircraft
In a few missions, extra AI aircraft are included but aren't available to the player in Free Flight. These aircraft include:
 * TBM Avenger ghost planes of Flight 19 - from Lost in the Triangle
 * Boeing 787-9 - from Paris Airshow Demonstration Flight, Loopy Larry & Jet Truck Drag Race

Missions and rewards
The inclusion of Missions adds a new facet to the simulation, adding task oriented goals, and encouraging users to fly worldwide, rather than just from their home field. Although a similar concept was available in previous versions, the new implementation of multipath & event oriented situations substantially extends the potential for user interaction. Pilots earn Rewards for completing various missions, and reaching specific accomplishments throughout the game, (in 'Free Flight'). Some of the rewards exist as hidden "easter eggs" to be discovered by pilots. Some missions have multiple and hidden rewards, receipt being dependent on performing additional actions. Some hidden rewards include: In each mission description, a map is included with it. It notes that they are for entertainment purposes. The maps and charts are supplied by Jeppesen.
 * Earning a postcard for spotting an item of interest.
 * Earning a badge for landing at a special airport, e.g., highest, most remote, lowest.
 * Earning a reward for completing a challenge not associated with a mission.
 * Earning a trophy for landing a number of times or the number of airports landed at.

Missions list
This is a list of all missions in Flight Simulator X (both Standard and Deluxe Edition, Acceleration missions are not included).

AI Aircraft
AI Aircraft are non-playable aircraft built only for scenery and ambience. They are also sometimes a key part in missions as well.

Add-ons
Players may also download additional aircraft from a number of user generated content websites which allow expansion and customization of the shipped game.

Demo versions
Flight Simulator X is notable for being the first product in Microsoft's Flight Simulator series to have a game demo, which contains a subset of features of the retail product (including a limitation to the duration of a flight) and requires Windows XP Service Pack 2 or Windows Vista for installation. The first limited demo of Flight Simulator X was released to the public on August 9, 2006, and put up for download on the website. Even though playable, the August demo represented a beta release of the product, and had a number of bugs, some of which were recognized in the official installation's README file. On October 2, 2006 the demo was superseded by a newer release, which, while having fewer bugs, is almost identical to the first demo. The DHC-2 Beaver was removed in favor of a Learjet 45. Both the demos feature St. Maarten, Netherlands Antilles and the surrounding area only, as opposed to the entire world. The main airport featured is Princess Juliana International Airport.

Service Pack 1
Microsoft released Service Pack 1 (SP1) for Flight Simulator X on May 15, 2007. It addresses the following problems:
 * Activation and installation issues
 * Performance enhancements, including multithreading of texture synthesis and autogen to provide modest performance improvements on multi-core computers
 * Third-party add-on issues
 * Content issues

Service Pack 2
Microsoft released another service pack for Flight Simulator X about the same time as its expansion pack (below). The update is primarily for Vista users that have DirectX 10 (DX10) compatible graphics adapters. The DX10 version takes advantage of DX10's improved shader model and more pixel pipelines and increased performance for Vista, approaching overall FSX performance on XP. It also adds the capability for players who do not have the expansion pack to participate in multiplayer activities with users of the expansion pack, along with support for multi-core processors. FSX-SP2 also fixes some more bugs over Flight Simulator X. SP1 is not compatible with SP2 or Acceleration in Multiplayer. People with SP1 cannot enter a session with players who have SP2 or Acceleration in Multiplayer. According to the documentation you are required to install Service Pack 1 before installing Service Pack 2.

Flight Simulator X: Acceleration
Microsoft released their first expansion pack for Flight Simulator in years, called Flight Simulator X: Acceleration, to the US market on October 23, 2007 rated E - E10+ for mild violence, and released to the Australian market on November 1, 2007 rated G. Acceleration introduces new features, including multiplayer air racing, new missions, and three all-new aircraft, the F/A-18A Hornet, EH-101 helicopter and the P-51D Mustang. Unfortunately, in many product reviews, users complained of multiple bugs in the initial release of the pack. One of the bugs, which occurs only in the Standard Edition of Flight Simulator X, is that the Maule Air Orion aircraft used in the mission has missing gauges and other problems, as it is a Deluxe Version-only aircraft. The new scenery enhancements cover Berlin, Istanbul, Cape Canaveral and the Edwards Air Force Base, providing high accuracy both in the underlying photo texture (60 cm/pix) and in the detail given to the 3D objects. Flight Simulator X: Acceleration takes advantage of Windows Vista and Windows 7 as well as DirectX 10. Because the expansion pack includes the content from the service packs, installing both is unnecessary.

Downloadable content
There are many downloads that both versions of Flight Simulator X can use, ranging from free aircraft and liveries to commercial, high-resolution scenery. They may change many aspects of the simulator, such as adjusting the visuals, gameplay, adding new features or content such as scenery objects and modifications. Numerous free downloads are available from community websites (such as Simviation.com, Avsim.com, and Flightsim.com) and the downloads include:


 * Civil jets
 * Prop planes
 * Helicopters
 * Vintage planes
 * Ultralights and gliders
 * Military aircraft
 * New paint jobs (repaints) for default aircraft
 * Missions
 * Conceptual (proposed future) aircraft


 * Add-on scenery
 * Miscellaneous items
 * Drivable cars
 * Utilities (tools such as a software development kit)
 * Additional AI aircraft, taking the form of real life airlines/aircraft
 * New "voicepacks" or small programs allowing FSX Air Traffic Control to refer to the user/ai aircraft using the correct callsign i.e. "Heron"
 * Legacy (real/fictional spacecraft)
 * System service packs which improve the performance of the program.

Unit availability
Microsoft announced in early 2010 that there was currently a shortage of the game in retailers, after receiving complaints. They expressed that they had not stopped manufacturing the popular simulation game, but that there was currently a shortage of available product activation keys. As a result they needed to make an engineering change which resulted in reduced output. New copies of the game were expected to return to shelves in May of 2010.

Overview
Flight Simulator X marks the tenth version of the popular line of flight simulators. It was officially released to the US market on October 17, 2006. According to Microsoft's Web site for the game, a standard edition features everything from navaids to GPS and airways. It also includes 18 planes, 28 detailed cities, and 40 airports with a deluxe version featuring 24 aircraft, and 38 cities. Flight Simulator X was officially unveiled at the 2006 International Consumer Electronics Show (CES) as a gaming showcase for Microsoft Windows Vista and is now also compatible with Windows 7. Microsoft released screenshots as well as a list of frequently asked questions as a press release on Microsoft Flight Simulator Insider, and numerous flight simulator communities. This also included mission-based gameplay with mission specific aircraft as well as an upgraded rendering engine capable of increased detail. Following the Electronic Entertainment Expo (E3) in May 2006, Microsoft published new screenshots, videos and an official trailer. The overall reaction by the community was quite positive, and the graphical quality of the simulator has greatly increased. Flight Simulator X has a required system rating of 3 for Windows Vista and a recommended rating of 5.

Missions and rewards
The inclusion of Missions adds a new facet to the simulation, adding task oriented goals, and encouraging users to fly worldwide, rather than just from their home field. Although a similar concept was available in previous versions, the new implementation of multipath & event oriented situations substantially extends the potential for user interaction. Pilots earn Rewards for completing various missions, and reaching specific accomplishments throughout the game, (in 'Free Flight'). Some of the rewards exist as hidden "easter eggs" to be discovered by pilots. Some missions have multiple and hidden rewards, receipt being dependent on performing additional actions. Some hidden rewards include: In each mission description, a map is included with it. It notes that they are for entertainment purposes. The maps and charts are supplied by Jeppesen.
 * Earning a postcard for spotting an item of interest.
 * Earning a badge for landing at a special airport, e.g., highest, most remote, lowest.
 * Earning a reward for completing a challenge not associated with a mission.
 * Earning a trophy for landing a number of times or the number of airports landed at.

Missions list
This is a list of all missions in Flight Simulator X (both Standard and Deluxe Edition, Acceleration missions are not included).

AI Aircraft
AI Aircraft are non-playable aircraft built only for scenery and ambience. They are also sometimes a key part in missions as well.

Add-ons
Players may also download additional aircraft from a number of user generated content websites which allow expansion and customization of the shipped game.

Demo versions
Flight Simulator X is notable for being the first product in Microsoft's Flight Simulator series to have a game demo, which contains a subset of features of the retail product (including a limitation to the duration of a flight) and requires Windows XP Service Pack 2 or Windows Vista for installation. The first limited demo of Flight Simulator X was released to the public on August 9, 2006, and put up for download on the website. Even though playable, the August demo represented a beta release of the product, and had a number of bugs, some of which were recognized in the official installation's README file. On October 2, 2006 the demo was superseded by a newer release, which, while having fewer bugs, is almost identical to the first demo. The DHC-2 Beaver was removed in favor of a Learjet 45. Both the demos feature St. Maarten, Netherlands Antilles and the surrounding area only, as opposed to the entire world. The main airport featured is Princess Juliana International Airport.

Service Pack 1
Microsoft released Service Pack 1 (SP1) for Flight Simulator X on May 15, 2007. It addresses the following problems:
 * Activation and installation issues
 * Performance enhancements, including multithreading of texture synthesis and autogen to provide modest performance improvements on multi-core computers
 * Third-party add-on issues
 * Content issues

Service Pack 2
Microsoft released another service pack for Flight Simulator X about the same time as its expansion pack (below). The update is primarily for Vista users that have DirectX 10 (DX10) compatible graphics adapters. The DX10 version takes advantage of DX10's improved shader model and more pixel pipelines and increased performance for Vista, approaching overall FSX performance on XP. It also adds the capability for players who do not have the expansion pack to participate in multiplayer activities with users of the expansion pack, along with support for multi-core processors. FSX-SP2 also fixes some more bugs over Flight Simulator X. SP1 is not compatible with SP2 or Acceleration in Multiplayer. People with SP1 cannot enter a session with players who have SP2 or Acceleration in Multiplayer. According to the documentation you are required to install Service Pack 1 before installing Service Pack 2.

Flight Simulator X: Acceleration
Microsoft released their first expansion pack for Flight Simulator in years, called Flight Simulator X: Acceleration, to the US market on October 23, 2007 rated E - E10+ for mild violence, and released to the Australian market on November 1, 2007 rated G. Acceleration introduces new features, including multiplayer air racing, new missions, and three all-new aircraft, the F/A-18A Hornet, EH-101 helicopter and the P-51D Mustang. Unfortunately, in many product reviews, users complained of multiple bugs in the initial release of the pack. One of the bugs, which occurs only in the Standard Edition of Flight Simulator X, is that the Maule Air Orion aircraft used in the mission has missing gauges and other problems, as it is a Deluxe Version-only aircraft. The new scenery enhancements cover Berlin, Istanbul, Cape Canaveral and the Edwards Air Force Base, providing high accuracy both in the underlying photo texture (60 cm/pix) and in the detail given to the 3D objects. Flight Simulator X: Acceleration takes advantage of Windows Vista and Windows 7 as well as DirectX 10. Because the expansion pack includes the content from the service packs, installing both is unnecessary.

Downloadable content
There are many downloads that both versions of Flight Simulator X can use, ranging from free aircraft and liveries to commercial, high-resolution scenery. They may change many aspects of the simulator, such as adjusting the visuals, gameplay, adding new features or content such as scenery objects and modifications. Numerous free downloads are available from community websites (such as Simviation.com, Avsim.com, and Flightsim.com) and the downloads include:


 * Civil jets
 * Prop planes
 * Helicopters
 * Vintage planes
 * Ultralights and gliders
 * Military aircraft
 * New paint jobs (repaints) for default aircraft
 * Missions
 * Conceptual (proposed future) aircraft


 * Add-on scenery
 * Miscellaneous items
 * Drivable cars
 * Utilities (tools such as a software development kit)
 * Additional AI aircraft, taking the form of real life airlines/aircraft
 * New "voicepacks" or small programs allowing FSX Air Traffic Control to refer to the user/ai aircraft using the correct callsign i.e. "Heron"
 * Legacy (real/fictional spacecraft)
 * System service packs which improve the performance of the program.

Unit availability
Microsoft announced in early 2010 that there was currently a shortage of the game in retailers, after receiving complaints. They expressed that they had not stopped manufacturing the popular simulation game, but that there was currently a shortage of available product activation keys. As a result they needed to make an engineering change which resulted in reduced output. New copies of the game were expected to return to shelves in May of 2010.

Overview
Flight Simulator X marks the tenth version of the popular line of flight simulators. It was officially released to the US market on October 17, 2006. According to Microsoft's Web site for the game, a standard edition features everything from navaids to GPS and airways. It also includes 18 planes, 28 detailed cities, and 40 airports with a deluxe version featuring 24 aircraft, and 38 cities. Flight Simulator X was officially unveiled at the 2006 International Consumer Electronics Show (CES) as a gaming showcase for Microsoft Windows Vista and is now also compatible with Windows 7. Microsoft released screenshots as well as a list of frequently asked questions as a press release on Microsoft Flight Simulator Insider, and numerous flight simulator communities. This also included mission-based gameplay with mission specific aircraft as well as an upgraded rendering engine capable of increased detail. Following the Electronic Entertainment Expo (E3) in May 2006, Microsoft published new screenshots, videos and an official trailer. The overall reaction by the community was quite positive, and the graphical quality of the simulator has greatly increased. Flight Simulator X has a required system rating of 3 for Windows Vista and a recommended rating of 5.

Sequel
On 22 January 2009, it was reported that development team behind the product was being heavily affected by Microsoft's ongoing job cuts, with indications that the entire Flight Simulator team would be laid off. The news was later confirmed by Microsoft officials stating they were committed to the Flight Simulator franchise, with expectations to continue product releases in the series, but had nothing specific to announce at that time. On 17 August 2010, Microsoft announced Microsoft Flight, a new simulation game that boasts a further improved graphics engine, and enhanced simulation features.

Standard vs. Deluxe Edition
Flight Simulator X was released in three editions, Standard, Deluxe and later Gold. The Deluxe Edition incorporates some additional features, including an on-disc Software Development Kit (SDK), three airplanes with the Garmin G1000 Flight Deck, and the ability for the player to act as Air Traffic Control (ATC) for other online users with a radar screen. The Deluxe Edition features 24 aircraft compared to 18 in the Standard Edition, 45 high-detail airports compared to 40, 38 high-detail cities compared to 28, and 51 structured missions compared to 30+. Microsoft Flight Simulator X: Gold Edition combines the Deluxe Edition and the Acceleration expansion pack into one.

New features
The new features in Flight Simulator X include:
 * Improved graphics including enhanced texture resolution, new Earth model facilitating polar flights, true road data, region-specific textures, minimal 3D animals, star constellations, etc. Also, the scenery textures now line up with the automatically generated (Autogen) buildings. Maximum rendering-engine-supported scenery resolution of 7 cm/pixel (not available with default scenery).
 * Airports now have jetways that move to the aircraft by the key combination Ctrl + J. (happens for AI aircraft automatically) Airport Vehicles also drive around the airport to you and AI aircraft. (Baggage cars, pushtrucks, fuel trucks, etc.) (International airports only)
 * The built-in GPS support has been upgraded to include Garmin G1000 integrated glass cockpit, (select aircraft in the Deluxe version only).
 * Improved ATC featuring certain non-FAA procedures where appropriate (for example, altimeter/QNH scale in metric units) and numerous minor updates such as an improved progressive-taxi feature.
 * Improved and new default aircraft including, for example, an Airbus A321. Default aircraft systems modeling is rather extensively improved, featuring, for example, APU, fire protection, passenger advisory sign switches etc.
 * Improved weather system, including better visibility modeling.
 * Revamped multiplayer functionality featuring Shared Skies, a feature allowing multiple users to share the same cockpit.
 * Tower Controller, a feature in the Deluxe version allowing users to simulate local control at many airports worldwide during multiplayer gaming.
 * Revamped sound system with support for 5.1 surround sound.


 * Proprietary SimConnectAPI to allow FSUIPC-like access to Flight Simulator functions and variables.
 * Mission engine allowing creation of dynamic missions with developer control of many simulation variables, sound file playback, AI aircraft traffic etc. in relation to what the user is doing — essentially an evolution over the APL and ABL adventure programming languages featured in previous versions of the software. Dozens of missions ship with the product.
 * Most of the vintage aircraft that were a key theme in the previous version have been dropped, with the exception of the DC-3 and Piper J-3. Both aircraft are featured in the default missions that ship with the product.
 * The maximum altitude in the game has been increased to 100,000,000 ft. Therefore, FSX maximum altitude is approximately 2.39 times the diameter of the Earth at the equator.
 * Camera shake in the virtual cockpit as the aircraft banks, accelerates, brakes, flies through turbulence etc.
 * Realistic flexible wings in some commercial airplanes: the wings flex while going through turbulence, increasing rate of ascent or descending, undergoing major plane movements, flaps being fully extended, general vibrations to the plane, etc.  An example of an aircraft with this wing movement is the Boeing 747-400.
 * New water effect which has 3D waves with curled up object refraction according to the wave movements and with sunshine reflection.
 * Ability to easily take a screenshot while in the game. Pressing the "V" key takes a picture of the game and saves it as a .bmp image in the "My Pictures" folder.
 * Aircraft can cast shadows on themselves.
 * Aircraft interiors and exteriors use different files. This allows an advanced user to take one exterior model of an Airbus A320 and merge it with an interior made by someone else.
 * Red Bull Air Race World Championship racing.

The update is primarily for Vista users that have DirectX 10 (DX10) compatible graphics adapters. The DX10 version takes advantage of DX10's improved shader model and more pixel pipelines and increased performance for Vista, approaching overall FSX performance on XP. It also adds the capability for players who do not have the expansion pack to participate in multiplayer activities with users of the expansion pack, along with support for multi-core processors. FSX-SP2 also fixes some more bugs over Flight Simulator X. SP1 is not compatible with SP2 or Acceleration in Multiplayer. People with SP1 cannot enter a session with players who have SP2 or Acceleration in Multiplayer. According to the documentation you are required to install Service Pack 1 before installing Service Pack 2.

Flight Simulator X: Acceleration
Microsoft released their first expansion pack for Flight Simulator in years, called Flight Simulator X: Acceleration, to the US market on October 23, 2007 rated E - E10+ for mild violence, and released to the Australian market on November 1, 2007 rated G. Acceleration introduces new features, including multiplayer air racing, new missions, and three all-new aircraft, the F/A-18A Hornet, EH-101 helicopter and the P-51D Mustang. Unfortunately, in many product reviews, users complained of multiple bugs in the initial release of the pack. One of the bugs, which occurs only in the Standard Edition of Flight Simulator X, is that the Maule Air Orion aircraft used in the mission has missing gauges and other problems, as it is a Deluxe Version-only aircraft. The new scenery enhancements cover Berlin, Istanbul, Cape Canaveral and the Edwards Air Force Base, providing high accuracy both in the underlying photo texture (60 cm/pix) and in the detail given to the 3D objects. Flight Simulator X: Acceleration takes advantage of Windows Vista and Windows 7 as well as DirectX 10. Because the expansion pack includes the content from the service packs, installing both is unnecessary.

Downloadable content
There are many downloads that both versions of Flight Simulator X can use, ranging from free aircraft and liveries to commercial, high-resolution scenery. They may change many aspects of the simulator, such as adjusting the visuals, gameplay, adding new features or content such as scenery objects and modifications. Numerous free downloads are available from community websites (such as Simviation.com, Avsim.com, and Flightsim.com) and the downloads include:

 * Utilities (tools such as a software development kit)
 * Additional AI aircraft, taking the form of real life airlines/aircraft
 * New "voicepacks" or small programs allowing FSX Air Traffic Control to refer to the user/ai aircraft using the correct callsign i.e. "Heron"
 * Legacy (real/fictional spacecraft)
 * System service packs which improve the performance of the program.

Unit availability
Microsoft announced in early 2010 that there was currently a shortage of the game in retailers, after receiving complaints. They expressed that they had not stopped manufacturing the popular simulation game, but that there was currently a shortage of available product activation keys. As a result they needed to make an engineering change which resulted in reduced output. New copies of the game were expected to return to shelves in May of 2010.
