& SYSTEMS DESCRIPTION
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.
