Alright - this one has a backstory So today we're sitting in English class and it's getting boring - so my pal Jake (the pilot) whips out an Air Canada union magazine. Needless to say it was weird reading patriotic business stuff, but this was the best comic ever: I think it should say "X-Plane.org" forms not "pilot" forums.

Enjoy! http://bit.ly/XgxczS

That's the point where the addon stops being true to the real deal. The "Airplane alt. at max diff." is meant for the small subdial at the bottom. With the addon, it is non-functional. The normal range for cabin altitude is from sea level or 1000ft above field elevation to about 8000ft at FL250. With 8000ft at FL250, you will be near maximum differential pressure. For FL200, a cabin altitude of 5500ft will give you a differential pressure that's very close to the maximum differential pressure. So take a safety margin and set it to 6000ft or 6500ft. Maybe this will help:
