I have not found a way to open the airstairs yet, I'm using the correct model but I don't know which button combo it is. I've tried them all. Also do the cargo doors open and the cockpit windows? :)

Assaign a key-stroke to 'CONCORDE VISOR RETRACT FULLY' and 'CONCODRE VISOR EXTEND FULLY'BTW, I do think that the Cargo Doors open.

I had the action names wrong:"Q) How do I extend the Stairs in the PMDG 737-700 With Stairs?A) The stairs extension and retraction are mapped to the Concorde Nose and Visor operations - go to your MS FS Key Assignments and assign a keystroke for "Extend Concorde Nose and Visor Fully" and "Retract Concorde Nose and Visor fully". Then, you'll be able to use those to move the stairs."That is from the FAQ anchored at the top of the forum :)

The cargo doors open with the Shift-E-2 command.Vin ScimonePMDGwww.precisionmanuals.comhttp://www.vinscimone.com/dancnkid.gif

To open the cargo doors press the button you would press to open the main exit, but continue to hold it down. At the same time press number 2. This should open the cargo hold doors.Warm RegardsKimberly
