Section III - SYSTEMS DESCRIPTION
GENERAL
Due to individual customer requirements, the equipment and furnishings may vary from the standard
installation. This Sub-section provides the typical installation of a flight compartment, vestibule area,
passenger cabin, galley, toilet compartment and cargo and accessory compartments.
FLIGHT COMPARTMENT
Stowages for miscellaneous flight and airplane equipment are provided in the left and right consoles
and on the flight compartment rear bulkheads. A tray is mounted in the structure below the pilot's seat
and can be swung out where it spans the area between both pilots' seats.
CREW SEATS
Seat Height Adjustment
Two crew seats, the pilot's and copilot‘s, are installed in the flight compartment and are adjustable for
height, fore and aft travel. Each seat is equipped with Teleflex inertia-reel type shoulder strap assembly
and lap belt. A life-jacket is stowed in a container mounted beneath each seat.
When the seat height adjustment handle is pulled upward, the height lock pins are disengaged from the
holes in the height lock plates. Spring tension, supplied by the two bungee cords, causes the seat to
rise.
When the adjustment handle is released, the height lock pins engage with holes in the height lock plates
to retain the seat pan in the required position.
Thigh Pad Position and Override
When the thigh support adjustment control knob is turned, two bevel gears mounted on the cross shaft
are rotated, which, in turn, rotate a threaded drive shaft under each thigh pad. The rotating drive shaft
causes crossheads to move towards or away from slide housings thereby raising or lowering the thigh
pads. The mechanisms are under constant spring tension within the slide housings and support the
thigh weight under normal conditions.
When the seat occupant uses the rudder controls of the airplane and thereby applies pressure to the
thigh pads, the spring tension is overridden and the crosshead slide tubes are pushed into the slide
housing allowing the thigh pad to move downwards. When the pressure on the thigh pad is relaxed, the
pad returns to its pre-set position.
Recline Adjustment Mechanism
When the recline control handle is pulled upward, a spring-loaded latch plate is withdrawn by a cable
from contact with a coarse threaded nut within the recline unit.
Application of pressure on the backrest rotates the threaded nut and allows the strut to be pushed into
the recline unit. The spring is compressed and the backrest reclines.
When the control handle is released, the spring-loaded latch plate re-engages with the coarse threaded
nut and the backrest is locked in the required position. If the control handle is again pulled upward, and
pressure released from the backrest, the spring, which was compressed by the recline operation, re-
asserts itself, causing the threaded nut to rotate in the opposite direction.
The strut pushes on the backrest, which returns to an upright position and is locked upon release of the
control handle.
