caution/advisory panel indicate the cabin door is not
closed and locked. This circuit is protected by the two.
5-ampere circuit breakers, placarded ANN PWR and
ANN IND located in the overhead circuit breaker panel
(fig. 2-6.).
d.
Cabin Emergency Hatch. The cabin
emergency hatch, placarded EXIT PULL, is located in
the right cabin sidewall just aft of the copilot's seat. The
hatch may be removed from the inside with a pull-down
handle. A flush-mounted, pull out handle allows the
hatch to be released from the outside. The hatch is of
the non-hinged plug type which removes completely
from the frame when the latches are released. The
hatch can be key locked from the inside to prevent
opening from the outside. The inside handle will unlatch
the escape hatch whether or not it is locked, by
overriding the locking mechanism. The keylock should
be unlocked prior to flight to allow removal of the
escape hatch from the outside in the event of an
emergency. The key remains in the lock when the hatch
is locked and can be removed only when the hatch is
unlocked. The key slot is in the vertical position when
the hatch is unlocked. Removal of the key from the lock
before flight assures the pilot that the hatch can be
removed from the outside if necessary.
2-10. WINDOWS.
a.
Cockpit Windows. The pilot and copilot
have side windows, a windshield and storm windows,
which provide visibility from the cockpit. The storm
windows may be opened on the ground or during
unpressurized flight.
b.
Cabin Windows. The outer cabin windows,
constructed of two-ply stretched acrylic, are of the
pressure type and an integral part of the pressure
vessel. The windows have flaps which may be removed
to permit visibility or installed to black out the windows.
2-11. SEATS.
a.
Pilot and Copilot Seats. The controls for
vertical height adjustment and fore and aft travel are
located under each seat. The forward and aft
adjustment handle is located beneath the lower front
inboard corner of each seat. Pulling up on the handle
allows the seat to move fore or aft. The height
adjustment handle is located beneath the lower front
outboard corner of each seat. Pulling up on the handle,
allows the seat to move up and down. Both seats have
adjustable headrests and armrests which will raise and
lower for access to the cockpit. Handholds on either
side of the overhead panels and a fold-away protective
pedestal step are provided for pilot and copilot entry into
the cockpit. For the storage of maps and the operator's
manual, pilot and copilot seats have an inboard-slanted
expandable pocket affixed to the lower portion of the
seat back. Pocket openings are held closed by shock
cord tension (fig. 2-9).
b.
Pilot and Copilot Seat Belts and Shoulder
Harnesses. Each pilot and copilot seat is equipped with
a lap-type seat belt and shoulder harness connected to
an inertia reel. The shoulder harness belt is of the Y
configuration with the single strap being contained in an
inertia reel attached to the base of the seatback. The
two straps are worn with one strap over each shoulder
and fastened by metal loops into the seat belt buckle.
The spring loading at the inertia reel keeps the harness
snug but will allow normal movement required during
flight operations. The inertia reel is designed with a
locking device that will secure the harness in the event
of sudden forward movement or an impact action.
