Presets
The International Standard Atmosphere is the reference model all aircraft and instruments are calibrated against. Temperature falls steadily through the troposphere at 6.5 °C/km, then holds constant in the stratosphere above the tropopause. Pressure and density decay roughly exponentially — at airliner altitude the air is only a quarter as dense as at sea level.

Governing equation
Reading this result: Below the 11 km tropopause, temperature falls at 6.5 °C/km — here it is -50 °C and the air holds 34% of sea-level density.
