V Best Rate-of-Climb Speed is the airspeed which delivers the greatest
Y
gain in altitude in the shortest possible time.

METEOROLOGICAL TERMINOLOGY

ISA. International Standard Atmosphere in which
1) The air is a dry perfect gas;
2)
3) The temperature gradient from sea level to the altitude at which
OAT (Outside Air Temperature) The free air static temperature, obtained ei-
ther from inflight temperature indicators adjusted for instrument error
and compressibility effects, or ground meteorological sources.
Pressure Altitude The altitude read from an altimeter when the barometric
subscale has been set to 29.92 inches Hg or 1013.2 millibars.
Station Pressure Actual atmospheric pressure at field elevation.
Wind The wind velocities recorded as variables on the charts of this hand-
book are to be understood as the headwind or tailwind components of
the reported winds.

POWER TERMINOLOGY

Take-off and Maximum Continuous The highest power rating not limited by
time.
Cruise Climb The power recommended for cruise climb.

ENGINE CONTROLS/INSTRUMENTS

Throttle Control. Used to control power by introducing fuel-air mixture into
the intake passages of the engine. Settings are reflected by readings
on the manifold pressure gauge or RPM for fixed pitch propellers.
Propeller Control. Connected to the propeller governor. It is used to maintain
engine/propeller RPM at a selected value by controlling blade angle.
Mixture Control. This control is used to set fuel flow in all modes of operation
and cuts off fuel completely for engine shutdown.
February 2008
The temperature at sea level is 15° Celsius (59° Fahrenheit);
the outside air temperature is -56.5°C (-69.7°F) is -0.00198°C
(-0.003566°F) per foot and zero above that altitude.
