source, cabin
pressure
can
be
supplied to
the etatic
pressure
instruments by breaking the
glass
in
the
face
of
the
vertioal
speed
iudioator.
With the alternate static
source
on, adjust
indicated airspeed
slightly
during climb or approach
according
to the alternate
static
source
airspeed
cal.ibration table
in
Section
5, appropriate
to vent/wÍndow(s)
configura-
tion, causing the
airplane to be flown
at the normal
operating
speeds.
Maximum
airspeed and altifneter variation
from
normal
is 4
knots and
30 feet over the normal
operating renge
with the window(s)
closed.
lVith
window(s)
open, larger
variations occur
near stall
speed.
flowever,
maximum
altimeter variation remains within
50 feet of
normal,

spin occur, the
following recovery
procedure
should
be used:
1. RETAR,D
THROTTLE
TO IDLE POSITION.
