DESCRIPTION

The rear or "rear wall" or "rear bulkhead" is the wall between the cockpit and the further compartments in the aircraft such as the areas of staff and passengers.
We also know the ‘rear pressure bulkhead, " but that is the circular shot in the back of the plane in the form of a spider web that will make for the air seal and the pressure to maintain. It also protects the aircraft against cracks due to the higher internal pressure.

We actually have 2 backs. The portion at the back of the Capt and the portion at the back of the FO.

Both backs are mainly equipped with the panels with the fuses (circuit breaker panels).

Because of lack of space in my homecockpit, only the 2 walls with the CB panels on the Capt side is a dummy jump seat to the wall to fill. The rear building with niches, between CB panels and flight crew compartment door, are omitted.

 

CONSTRUCTION OF THE BACKS

The two backs are made of MDF-panels and a few tussenribben of wooden bars for strength.

Both backs are built so that the wall fits into the metal frame of the cockpit. They may be so separate in the metal frame of the cockpit sliding.
The width of the Capt-back amounts 900 mm and the Fo rear is 925 mm wide. The width of the doorway is 580 mm. So a 2 cm wider than the original version.

The MDF panel on the inside 9 mm thick. The CB-panels and other parts are screwed. The panel on the outside for the finish 3 mm thick. This panel has one side that is white and is normally used for the rear and the inside of a cabinet close.

The ribs are made of wooden slats from the Brico of 93 mm wide and a thickness of 18 mm. The total thickness of a wall on 130 mm.

These ribs are first glued against the MDF panels and then with a few screws extra confirmed.

The backs Capt/FO are both in the corners with a recess in which a metal ingot that policy is attached to the top/middle of the window opening.
This bar is a part of the construction of the cockpit and is also to be seen in a real cockpit.

Also on the FO rear wall there is a recess for the mounting of a fire extinguisher. This niche is 105 mm wide, 670 mm high and 25 mm deep.

At the top of the Capt/FO-rear wall there is a round opening provided for the construction of a ‘Dome light’.

Both backs are to the inner sides of the doorway with stofferingsnagels. The nails have a round head with a diameter of 10 mm. The distance between the nails is from heart to heart 40 mm.

 

 

The nisopeningen in the corners of both walls are cut out and intended for the conduction of the metal upper rail have a length of 241 mm and a width of 102 mm.
Below one can find extra dimensions how the nisbehuizing must be built.

(OEM=Original Equipment Manufacturer)

The niches have on the inside a sloping and undulating bottom edge. This is obtained by using the corners to fill with putty and then gladgeschuurd.

In the niche at the bottom of the inner opening, I have a metal plate attached with a cut-out opening in the shape of an inverted U. This metal plate in the shape of a U, serves as conductor of the ‘upper rail’ (Win P2). The ‘upper rail’ peace just in this guide.

 

CONFIRMATION OF THE BACKS

The rear walls are each separately mounted on 3 verankeringpunten: side, top and bottom.

The side and top are anchored with a bolt through the metal cockpitframe and the wooden wandgedeelte. The bottom of the wall is on the inside of the cockpit, mounted with an L-profile which is against the wall and floor of the cockpit is screwed.

These three anchoring points can be afterwards easily unscrewed and removed and then the wall road slide for any work to perform in the cockpit.

 

 

FINISHING AND PAINTING

Both backs are on the inside of the cockpit painted with a primer.

Thereafter, the back panel FO side painted in a black color (satin) and the rear CAPT side, the left half in Boeinggrijs and the right half in a black color (same as FO).

The 2 niches have a Boeinggrijze colour.
