B-2. Meteorological Terminology.
Barometric pressure corrected to sea level.
Free air temperature is the free air static temperature, obtained either from
ground meteorological sources or from inflight temperature indications adjusted
for compressibility effects.
The number actually read from an altimeter when, the barometric scale
(Kollsman window) has been set to 29.92 inches of mercury (1013 millibars).
International Standard Atmosphere in which:
a. The air is a dry perfect gas;
b. The temperature at sea level is 59 degrees Fahrenheit, 15 degrees Centigrade;
c. The pressure at sea level is 29.92 inches Hg;
d. The temperature gradient from sea level to the altitude at which the
temperature is - 69.7 degrees Fahrenheit is - 0.003566 Fahrenheit per foot and
zero above that altitude.
Indicated pressure altitude corrected for altimeter error.
The wind velocities recorded as variables on the charts of this manual are to be
understood as the headwind or tailwind components of the actual winds at 50
feet above runway surface (tower winds).
