Meteorological Terminology
ISA
International Standard Atmosphere in which:
The air is a dry perfect gas;
The temperature at sea level is 15° Celsius (59° Fahrenheit);
The pressure at sea level is 29.92 inches hg. (1013 mb);
The temperature gradient from sea level to the altitude at which
the temperature is -56.5°C (-69.7°F) is -0.00198°C
(-0.003566°F) per foot and zero above that altitude.
OAT
Outside Air Temperature is the free air static temperature,
obtained either from inflight temperature indications or ground
meteorological sources, adjusted for instrument error and
compressibility effects.
Indicated Pressure
The number actually read from an altimeter when the barometric
Altitude
subscale has been set to 29.92 inches of mercury (1013 millibars).
Pressure Altitude
Altitude measured from standard sea-level pressure (29.92 in. Hg)
by a pressure or barometric altimeter. It is the indicated pressure
altitude corrected for position and instrument error. In this
handbook, altimeter instrument errors are assumed to be zero.
Station Pressure
Actual atmospheric pressure at field elevation.
Wind
The wind velocities recorded as variables on the charts of this
handbook are to be understood as the headwind or tailwind
components of the reported winds..
