Never Exceed Speed or Mach Number is
the speed limit that may not be exceeded at
any time.
V
NO
Maximum Structural Cruising Speed is the
speed that should not be exceeded except
in smooth air and then only with caution.
V
S
Stalling Speed or the minimum steady
flight speed at which the airplane is con-
trollable.
V
SO
Stalling Speed or the minimum steady flight
speed at which the airplane is controllable
in the landing configuration.

Best Angle-of-Climb Speed is the airspeed
which delivers the greatest gain of altitude
in the shortest possible horizontal distance.
V
Y
Best Rate-of-Climb Speed is the airspeed
which delivers the greatest gain in altitude
in the shortest possible time.
(b) Meteorological Terminology
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
29.92 inches Hg (1013 mb); The tempera-
ture 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.
OAT Outside Air Temperature is the free air
static temperature obtained either from
inflight temperature indications or ground
meteorological sources, adjusted for in-
strument error and compressibility effects.
