Yea, we currently have a line item to manually close the outflow valves. Keeps the birds out, so the story goes. But it's just asking for trouble, if you ask me . . . like this . . . Had a 767 freighter departure tbe other day. The crew was onboard and had closed the door. I wanted in but couldn't open the door. I had to scribble a note and hold it up to the window. "You're pressurized. Open the door!"

Are those valves animated on the PMDG 747?

Why not contact them on the ground comm?

The stairs run right next to the Capt's side window. It was more fun to bang on the window and give 'em ThE eYe.
