CESSNA
MODEL 172R
NOTE
Accidental opening
of
a cabin door
in flight due to improper
closing does not constitute a
need to
land the airplane.
The
best procedure is
to set
up the airplane
in
a
trimmed
condition at approximately 75 KIAS, momentarily shove the
door outward slightly, and forcefully close and lock
the door.
Exit
from
the airplane is accomplished by rotating
the door
1
handle from the LOCK position, past the CLOSE
position, aft to the
OPEN position and pushing the door open.
To
lock the airplane,
lock the right cabin door with the inside handle, close the left
cabin
door, and using the ignition key, lock the door.
The
left
and right cabin doors are
equipped with
openableÿ6***)
windows which are held in the closed position by a detent equipped
latch on the lower edge of the window frame. To open
the windows,
|
rotate the
latch upward. Each window is equipped with a spring-
loaded retaining arm which will help
rotate the window outward, and
/ÿ***N
hold it
there. If
required, either window
may be opened
at
any.
'
speed
up
to 163 KIAS. The rear side
windows
and rear windows are
of
the
fixed type and cannot be opened.
CONTROL LOCKS
A
control lock is provided
to
lock the aileron
and
elevator control
surfaces
to prevent
damage
to
these
systems
by wind
buffeting
while the airplane is parked. The lock
consists of
a shaped steel
rod
and flag.
The flag identifies the control lock and cautions about its
removal before starting the engine. To install the control lock, align
the hole in
the top
of the pilot’s control wheel shaft with the hole in
the top of the shaft
collar on the instrument
panel and
insert the rod
into the aligned holes. Installation
of
the lock will secure
the ailerons
in a neutral position and the elevators in a slightly trailing edge
down position. Proper installation
of
the lock will place the flag over
the ignition
switch. In areas where
high or gusty winds occur,
a
control surface lock
should
be installed over the vertical stabilizer
and
rudder. The control lock and any other
type of
locking device
should be removed prior
to
starting the engine.
