How do I get the stairs for the plane, I manage to open the doors but no stairs are there.

First, you need to make sure you're using a model that includes stairs. Not every model does.Assuming that you have selected a model with stairs, PMDG has assigned opening and closing of the stairs are to the extending and retracting of the concorde's nose in FS9. By default, this is not assigned to any keyboard shortcut. You need to do this manually.Next, go into the Assignments... dialog (I can't remember which FS menu this option is on...sorry) and give the extend and retract some key combination. I use SHIFT-O (open) and SHIFT-C (close).I'm sorry if my instructions are a little vague. I am not at a computer with FS installed. I hope that helps.Bob
