In Bangkok, there are two airports.  The old one is Don Mung Airport (VTBD) and the new one is Suvarnabhumi Airport (VTBS)

The name “Suvarnabhumi” means “The golden land” or the land of abundance. Suvarnabhumi back to the Budda Era means the southeast Asia. This name was given by the King Bhumiphol (King Rama IX) to the new airport that replaces Don Maung Airport.  This is the gateway to Thailand. The airport project was first established in 1973. Finally after years of waiting, it was officially open in 29th September 2006. Murphy/Jahn Architects designed this airport with glass walls, metal frames and canvas. The airport has 2 parallel runways. It has a total of 120 parking bays (51 with contact gates and 69 remote gates). 
This airport is not available  in default FSX because it was opened after the release of the game.  This scenery is just for FSX Acceleration and Prepare3D only.  This scenery is brand new and made with the recent knowledge of scenery making to optimize the frame rate to be as good as possible.

Features

• Main terminal and concourses was made in detail including 3d metal frames. All the parts has been design to make frame rate better than any other previously released versions of this airport. There is no interior structures in this version. Unnecessary details were discarded to make frame rate at its best.  Yet, the outside details that you can see from the aircraft you flying are magnificent.
• Jetways were made in detail but only static ones are provided. 
• Photoscenery was used for the whole area of the airport.  Unfortunately, the maximum resolution of satellite image in this region is about 60 cm/pixel.
• Custom made lines, taxiway and runway.  Those are made with fully optimized texture.  Frame rate is much better than previous version.
• FSX style surfaces cover on asphalt runway and taxiway.  Rain effect and some light reflection are visible.
• Real 3D grass changes its color through the season.
• Custom made 3d taxiway edge lights with new technique.  Less impact on frame rate from almost 4000 lights.  Light splash for the entire light poles, illuminate the entire airport with realistic night light.
• Real 3D ALSF-2 landing light system.
• Runway guard lights to all runway holding points.
• Visual Guide Docking System provide guide when parking to the contact gate.
• Animated Thai Maintenance Hangar doors.  You can open them by dial Nav2 to 112.00.
• Real 3d cars in the parking lot.  The models are custom made and available in Thailand.
• Service vehicles in FSX have some good features but we cannot change the livery for only one airport.  We have made some animated vehicles for this airport of which are Thai Airways livery.  However, today technology is still not possible to make this vehicle recognize your aircraft and wait for you.  They will continue running on their path without crash.
• Surrounding area including Thanacity Golf Course, King Mongkut Institute of Technology, Logistic Center, Airport link station and Burapha Vitae Expressway.
• Charts are not included but you can get the real thing from http://www.aerothai.co.th
• AES supported from AES V2.30.x
