I guess you mean the barometric pressure? This has nothing to do with the min/max flight levels. The altimeter must be adjusted to the local pressure. This is information that the airplane receives from flight control. If the altimeter isn't calibrated it will show a wrong altitude. This is exactly what you can experience if you have a watch with built-in altitude meter. It must be calibrated every time you use it (set a reference altitude).

FL 180 will still be the minimum flight level in effect. FL 600 will always be the maximum no matter what. Even though the table that you're thinking of in the AIM will state that the lowest flight level will be 190, you'll still transition at FL180. ATC will probably give you a minimum of FL 200 for Boston to Detroit. In real life, it doesn't work that way. You can get FL180 if you want.

I don't understand the question. I suppose the minimum would have to be 1,000 feet above persons and property as per FAR's, after that, you can drag the damn gear through the corn if you want. You can fly as high as you want, over 60,000 feet the FAA allows you to go on your own, at that altitude or above, they don't intervene.
