Seats
The cockpit contains seats for a Captain, First Officer, and Observers. All seats,
except the aft observer’s seat, have electrical and/or manual adjustments. If the
electrical control or power of a seat fails, full movement of the seat is possible
through manual operation. All seats are equipped with seat belts and dual shoulder
harnesses with inertia reels. All seats, except the aft observer’s seat, are
additionally equipped with a crotch belt. On some seats the headrest can be
adjusted vertically as well as tilted to several positions including a fully horizontal
(stowed) position.
Seats for the Captain and First Officer are powered by two electric motors. The
motors provide vertical and horizontal adjustments. The recline, lumbar support,
armrest, and thigh support controls are manually operated. The Captain and First
Officer’s seat has a recline limit switch which inhibits outboard movement of the
seat whenever the backrest is reclined more than one notch from the upright
position. The seat indicator incorporates two numerical index scales; one scale
representing the vertical position of the seat and the other the horizontal.
Horizontal control switches permit the Captain and First Officer seats to be moved
full aft and outboard to facilitate exit.
The right Observer’s seat is also powered operated to provide vertical adjustment.
The recline, lumbar support, armrest, and swivel controls are manually operated.
The swivel control permits adjustment between forward and outboard facing
positions. When facing forward, the seat has vertical capability. When facing
outboard, the seat does not have vertical capability.
On power-operated seats, turning the power switch to OFF after adjusting the seat
for takeoff or landing prevents seat movement (runaway seat) if an electrical short
should occur.
The aft Observer’s seat is a folding, nonadjustable type bolted directly to the floor
structure.
The Pilot Eye Locator consists of optical painted white lines on the instrument
panel.
Doors
P - There are eight cabin doors, three lower cargo doors, a cockpit door, and a door
for each lavatory.
If any door is open on the ground, a level 1 DOOR OPEN alert appears on the SD.
When the first engine is running, the alert then changes to a level 2 alert
identifying the specific door.
