Anyone out there can help me of how to make the stair shown... What key?... I did shut the engine down and have tried a number of way, but still couldn't do it. Any help would be much appreciated. Pao,

From the www.precisionmanuals.com 737 OIC FAQ:"I.2) Map keys to operate the Air Stairs up and down:In order to animate the operation of the Air Stairs, we installed a very complex articulated stair model into the 737NGs that use the stairs in the real world. (You can tell this from reading the information in the User Interface....)If you have an airplane that uses Air Stairs and you would like to operate them, the following are some easy steps to help you! * Within MSFS, access the CONTROLS menu, then the ASSIGNMENTS menu. * Assign a key to EXTEND CONCORDE NOSE and VISOR FULLY (I recommend CTRL+F10) * Assign a key to RETRACT CONCORDE NOSE and VISOR FULLY (I recommend CTRL+F9) Now the air stairs are mapped to your CTRL+F9 and CTRL+F10 keys so that you can operate them within MSFS!It is important to note that not every 737 includes the stair animation, as not all airlines order the stairs from Boeing! The stairs add a significant amount of weight to the basic shell of the airplane, so many airlines choose not to have them installed.You can normally determine if you model has air stairs by reading the User Interface information about the 737 you have chosen!"
