(6) Adjust the recline angle until the shoulders are positioned at the
desired sitting angle.
(7) Adjust the lumbar in/out support and up/down support to the desired
positions.
(8) Using the vertical adjustment control and fore/aft track lock control,
position the seat to properly align the occupant with the Design Eye
Locator on the center windshield post.
(9) Verify thigh pads “break away” to allow sufficient movement on the
rudder pedals and toe brakes.
C. Operation of the Observer’s Seat:
(See Figure 20.)
The observer’s seat is normally stowed until needed. A four (4) point
harness is used to restrain the occupant.
The seat is accessed by lifting the handle at the base of the seat and
manually pulling the seat out of the stowage area. When the seat is out, the
same handle is used to allow movement to either of two (2) use positions,
or to allow stowage.
With the seat out, the seat pan is pushed down for occupancy and held
down by the occupant’s weight. Upon rising, the seat pan automatically
retracts.
CAUTION
ENSURE THE LAPBELT RESTRAINT IS PROPERLY
STORED IN THE RESTRAINT POCKET PRIOR TO
ALLOWING THE SEAT PAN TO CLOSE. FAILURE TO
DO SO COULD CUT OR FRAY THE LAPBELT
RESTRAINT.
When seated, the following adjustments can be made:
•
Forward or Aft Positioning: Lifting a paddle-type lever on the right
hand side of the seat allows positioning and locking in a forward or
aft position. There are no intermediate positions.
•
Vertical Positioning: Rotation of a handle on the right hand side of
the seat allows a six (6) inch vertical positioning range. To go up, the
occupant must lift some weight off of the seat. To go down, the
occupant must remain on the seat.
•
Swivel Positioning: Rotation of a handle on the left hand side of the
seat allows counter-clockwise rotation to a forward-facing or
rearward-facing position. There are no intermediate positions.
•
Recline Positioning: Rotation of a handle on the right hand side of
the backrest allows reclining up to thirty (30) degrees from vertical in
three (3) degree increments. The backrest will automatically return
to the upright position by rotation of the handle and removing weight
from the backrest.
•
Armrest Positioning: The left and right armrests are stowed in a
cavity on the backrest shroud. For use, they are pulled out and
rotated forward to the normal position. Adjustment controls are
located on the forward underside of the armrests.
