TI
TRUE
AIRSPEED
INDICATOR
A
true
airspeed
indicator-is
available to
replace
the
standard
air-
speed
indicator
in
your
airplane.
The
true
airspeed
indicator
has
a
cali-
brated
rotatable
ring
which
works
in
conjunction
with
the
airspeed
indi-
cator
dial
in
a
manner
similar
to
the
operation
of
a flight
computer.
TO
OBTAIN
TRUE
AIRSPEED,
rotate
ring
until
pressure
altitude
is
aligned
with outside
air
temperature
in
degrees
Fahrenheit.
Then
read
true
airspeed
on
rotatable
ring
opposite
airspeed
needle.
NOTE
Pressure
altitude
should not
be
confused with
indicated
altitude.
To obtain
pressure
altitude,
set barometric
scale
on
altimeter
to
"29.92"
and
read
pressure
altitude
on
altimeter.
Be
sure
to
return
altimeter barometric
scale
to
original
barometric
setting
after
pressure
altitude
has been
obtained.
