Laminar Research has released version 7.20 of their popular flight simulator X-Plane. Here are the new features since 7.15:
Pressurization system is operative and functional. Open Jason Chandlers Malibu that comes with X-Plane 7.16. Twiddle the lower-left knob to set the altitude you want the cabin at (the air pressure in the cabin, or how it "feels" in the cabin...this is typically about 8,000 feet in an airliner flying at 36,000 feet)... the top digital tape will scroll to the cabin altitude you want. The tape below will scroll as well... this is showing the maximum altitude the airplane can be and still give you the cabin altitude you desire.
