Abstract:	THE OPERATIONAL FLIGHT LEVELS Of long-range turbojet aircraft normally are the environmental layers above and below the tropopause. The air mass below the tropopause down to the earth’s surface is the troposphere, and its characteristic features are these: (a) there is water in it (either gaseous, liquid, or solid), and (b) the temperature within the mass generally decreases with altitude. Above the troposphere is the stratosphere, and the dividing level between both air masses is the tropopause.
