Hi boing,

Glad you found my videos.

There is no magic button... but you can do it easily enough this way:

Load the default Baron 58.
Switch to the 2D cockpit.
Turn all switches and knobs off.
Load the 757.

I will be making more videos (some day, no time right now- they take a LOT of time to make!) and one of them will be the shutdown and secure lists.

All the information I'm conveying in my videos comes directly from the Captain Sim manuals, specifically the checklists.  The shutdown/secure lists are in there. :)
