hatch is being removed. On reinstalling the hatch, the
electrical disconnect should be reconnected before
moving the hatch into the closed position.
2-13. CABIN DOOR CAUTION LIGHT.
As a safety precaution, two illuminated MASTER
CAUTION lights on the glare shield and a steady
illuminated CABIN DOOR yellow caution light on the
annunciator panel indicate the cabin door is not closed
and locked
. This circuit is protected by two 5-ampere
circuit breakers, placarded ANN PWR and ANN IND ,
located on the overhead circuit breaker panel.
2-14. WINDOWS.
Do not look directly at the sun through the
polarized windows. Possible eye damage
could result.
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
flight
. Lighting and visibility are provided in the cabin
by windows on each sidewall and by a pair of smaller
windows aft of the cabin entrance door.
b. Cabin Windows C . The outer cabin
windows of two-ply construction are the pressure type
and are integral parts of the pressure vessel
. Inboard
of each pressure cabin window are two inner windows
of bonded laminate construction
. Each consists of a
tinted neutral gray polarized film between two pieces
of clear acrylic
. These windows are designed into a
sealed unit . The innermost window that faces the
inside of the cabin has a protruding knob near the
edge and turns freely in its frame
. By rotating this
window the polarized windows may be so aligned as to
permit varying degrees of light to pass, thereby
regulating light intensity.
c. Cabin Windows D T . The outer cabin
windows of two-ply construction are the pressure type,
and are integral parts of the pressure vessel
. Each
cabin window has a vertical sliding curtain to regulate
light through the window.
2-15. SEATS.
a. Pilot and Copilot Seats. The pilot's and
copilot's seats are separated from the cabin by a
removable partition with lockable sliding doors
. Refer
to Figure 2-13. The controls for vertical height
adjustment and fore and aft travel are located under
each seat
. The fore and aft adjustment handle is
located beneath the bottom front inboard corner of
each seat
. Pulling up on the handle(s) releases the
seat position lock allowing the seat to move as
desired
. 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 expandable pocket affixed
to the lower portion of the seat back
. Pocket openings
are held closed by shock cord tension.
WARNING
CAUTION
Depending upon individual seat
adjustment, certain controls and switches
may become inaccessible with the harness
locked
. Each pilot and copilot should
determine for himself to what extent a
locked shoulder harness would interfere
with aircraft and systems control.
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 in 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.
