MODEL
172R
SECTION 7
AIRPLANE
&
SYSTEMS DESCRIPTION
A manually
adustable seat belt/shoulder harness
assembly is
available for all
seats.
To use
the manually adjustable
seat
belt/shoulder
harness,
fasten and adjust the
seat
belt/shoulder
harness first.
Lengthen the
seat belt as required by pulling on the release
strap on the belt.
Snap the connecting link
firmly
into the buckle, then adjust
to
length. A properly adjusted harness will permit the
occupant to
lean
forward enough
to
sit
erect,
but
prevent
excessive
forward
movement
and
contact
with objects during sudden deceleration.
Also, the pilot
must
have
the freedom to reach all controls easily.
Disconnecting the manually adjustable
seat
belt/shoulder harness
is accomplished
by pushing the button on the buckle
to
release the
connecting link.
ENTRANCE DOORS AND
CABIN WINDOWS
Entry to, and exit from the airplane is accomplished through
either of
two entry
doors, one on each
side
of the cabin
at
the
front
seat
positions (refer
to
Section
6
for
cabin and cabin door
dimensions). The doors incorporate a recessed exterior door handle,
a conventional interior door handle, a key operated
door
lock (left
door only), a door
stop mechanism, and openable windows in both
the left and right doors.
The door latch design on this model requires that the
outside
door
handle
on the pilot and front passenger doors
be
extended
out whenever the doors are open. When
closing the
door,
do
not
attempt
to
push the door handle in
until the door is fully shut.
To open the doors
from outside the airplane, utilize the recessed
door handle
near
the
aft edge of either door by grasping the forward
edge
of
the handle
and pulling outboard. To close or open the doors
from
inside the airplane, use the combination door handle and
arm
rest.
The inside door handle has three positions and a placard
at
its
base which reads OPEN, CLOSE,
and
LOCK. The handle is spring
loaded
to the CLOSE (up) position. When the door has been pulled
shut and latched, lock it by rotating the door handle forward
to
the
LOCK
position
(flush with the arm
rest).
When the handle is rotated
to
the LOCK position, an over
center
action will hold it in that
position. Both cabin
doors
should be locked prior
to flight, and
should
not
be opened intentionally during flight.
