General
Outside
Air Temperature is the free air
static temperature, obtained either from
inflight temperature indications ad-
justed for instrument error and com-
pressibility effects, or ground
meteorological sources.
The
number
actually read from an
altimeter
when
the
barometri
c
subscale
has been
set
tc
29.92 in. Hg
(1013.2 millibars).
I
Altitude measured
from
standard
sea
level pressure (29.92 in. Hg)
by
a
pressure
or barometric altimeter. It is
the
indicated
pressure
altitude
corrected for position and instrument
error.
In
this
handbook,
altimeter
instrument errors are assumed
to
be
zero. Position errors may be obtained
I
from
the
Altimeter Correction graph.
Actual atmospheric pressure

elevation.
The
wind
velocities recorded as vari-
ables
on
the charts of this handbook
are to
be
understood as the headwind
or
tailwind components of the reported
winds.
