Best Angle-of-Climb Speed is the airspeed
which
delivers the greatest gain of altitude
in the shortest possible horizontal distance.

METEOROLOGICAL TERMINOLOGY
ISA International Standard Atmosphere in
which
(1) The air is a dry perfect gas;
(2) The temperature at sea level is 15
0
Celsius (59
0
Fahrenheit);
(3) The pressure at sea level is 29.92
inches Hg. (1013.2 millibars);
(4) 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.

effects, or ground'meteorological sources.
