Outside Air Temperature is the free air static
temperature obtained from inflight temperature
indications or from ground meteorological sources.
It is expressed in either degrees Celsius or degrees
Fahrenheit.
Pressure Altitude (PA) is the altitude read from the
altimeter when
adjustment has been set to 29.92 in.Hg (1013 mb)
corrected for position and instrument error. In this
Handbook, altimeter instrument errors are assumed
to be zero.
Standard Temperature is the temperature that would
be found at a given pressure altitude in the standard
atmosphere. It is 15°C (59°F) at sea level pressure
altitude and decreases approximately 2°C (3.6°F)
for each 1000 feet of altitude increase. See ISA
definition.
Brake Horsepower is the power developed by the
engine.
Maximum Continuous Power is the maximum power
that can be used continuously.
Manifold Pressure is the pressure measured in the
engine's induction system expressed as inches of
mercury (in.Hg).
Revolutions Per Minute is engine rotational speed.
Static RPM is RPM attained during a full-throttle
engine runup when the airplane is on the ground
and stationary.
Turbine Inlet Temperature is the temperature
measured in front of the first stage turbine nozzle
valves.
