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 1013.2 mbar (29.92 inches Hg);
The temperature gradient from sea level to the altitude at which the
temperature is -56.5°C (-69.7°F) is -0.00198°C (-0.003564°F) per foot and
zero above that altitude
MSL
Mean Sea Level is the average height above the surface of the sea for all
stages of tide
AGL Above Ground Level is the height of the aircraft above the ground
OAT
Outside Air Temperature is the free air static temperature surrounding the
aircraft
Pressure
Altitude
Altitude measured from standard sea level pressure (1013.2 mbar, 29.92 in.
Hg) by a pressure or barometric altimeter
It is the indicated pressure altitude corrected for position and instrument
error. In this Manual, altimeter instrument errors are assumed to be zero
