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

Meteorological Terminology
Indicated Altitude
The number actually read from an altimeter when the barometric
subscale has been Pressure set to 29.92 in hg (1013.2 mbar).
ISA
International Standard Atmosphere in which:
−
the air is a dry, perfect gas
−
the temperature at sea level is 59 °F (15 °C)
−
the pressure at sea level is 29.92 in hg (1013.2 mbar)
−
the temperature gradient from sea level to the altitude at
which the temperature is -69.7 °F (-56.5 °C) is -0.003564
°F (-0.00198 °C) per foot and zero above that altitude.
SAT
Static Air Temperature is the temperature of the air the aircraft is
flying through. SAT indication on the ground may not be
accurate.
Pressure
Pressure Altitude measured from standard sea level pressure.
Altitude
(29.92 in hg/1013.2 mbar) by a pressure or barometric altimeter.
It is the indicated pressure altitude corrected for position and
instrument error. In this AFM, 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
AFM are to be understood as the headwind or tailwind
components of the reported winds.
ELEV
Geographical altitude of landing field.
Icing Conditions
Can exist when the Outside Air Temperature (OAT) on the
ground and for takeoff, or Total Air Temperature (TAT) in flight, is
10 °C or colder, and visible moisture in any form is present (such
as clouds, fog or mist with visibility of one mile or less, rain,
snow, sleet and ice crystals).
Can exist when the OAT on the ground and for takeoff is 10 °C
or colder when operating on ramps, taxiways or runways, where
surface snow, ice, standing water, or slush may be ingested by
the engine, or freeze on the engine, or the engine nacelle.
Can exist when there are visible signs of ice accretion on the
aircraft.
Severe Icing Conditions
Severe icing may result from environmental conditions during
flight in freezing rain, freezing drizzle, or mixed icing conditions
(supercooled liquid water and ice crystals) which may result in
ice build-up on protected surfaces exceeding the capability of
the ice protection system, or may result in ice forming aft of the
protected surfaces.
