STALLS
SECTION
4
NORMAL
PROCEDURES
The stall characteristics are conventional. An approaching stall
is
indicated by a stall warning horn which
is
activated between
five
and ten
KTS above stall speed. Mild airframe buffeting and gentle pitching may
also precede the stall.
The gross weight stalling speed with power off and full flaps
is
44
KIAS.
With the flaps up this speed
is
increased. Loss
of
altitude during stalls varies
from
100
to
275
feet, depending on configuration and power.
NOTE
The stall warning system
is
inoperative with the
master switch
OFF.
During pretlight, the stall warning system should be checked
by
turning
the master switch
ON, lifting the detector and checking to determine if the
horn
is
actuated. The master switch should
be
returned to the
OFF
position
after the check
is
complete.
4.39
TURBULENT
AIR
OPERATION
In keeping with good operating practice used in all aircraft, it
is
rec-
ommended that when turbulent air
is
encountered
or
expected, the airspeed
be reduced to maneuvering
·speed to reduce the structural loads caused
by
gusts and to allow for inadvertent speed build-ups which may oecur as a
result of the turbulence
or of
distractions caused by the conditions. (See
Subsection 2.3)
4.41
WEIGHT AND BALANCE
It
is
the responsibility of the owner and pilot to determine
that
the air-
plane remains within the allowable weight
vs.
center
of
gravity envelope
while in flight.
For
weight and balance data, refer to Section 6 (Weight and Balance).
