: A striking fact for flight planning is that 50% of the atmosphere's total mass is concentrated within the first 5 km (approx. 18,000 ft) of the Earth's surface.

In the subject for the JAA ATPL theory, one of the most interesting and critical concepts is the relationship between temperature and the height of the tropopause . While it might seem counterintuitive, the tropopause is significantly higher and much colder over the equator than it is over the poles.

Understanding these divisions is vital because crossing the tropopause often means a transition into the , where air becomes extremely stable, vertical currents cease, and many weather hazards like thunderstorms are left below. : A striking fact for flight planning is
