The flight deck compartment floor, wall and ceiling linings provide thermal insulation, sound proofing and interior furnishing trim above the floor level of the compartment
The flight compartment is thermally insulated and sound proofed with glass wool insulation blankets and frame wrappings, which are shaped to suit the aircraft structure. Each insulated blanket consists of layers of glass wool contained in a reinforcing fabric, with an outer skin of non-porous fire proof plastic film. These blankets are fabricated to include self attaching tape, hinged strips and drain holes, using waterproof adhesive, stitching and adhesive sealing tapes.
The insulating blankets are contained between the fuselage skin and the furnishing trim, this furnishing trim consists of ceiling and side wall panels, with glass fibre sills, fairings and insulation covers surrounding the windshield and windows.
The insulation material itself is attached to a support structure which itself is sandwiched between the fuselage frame and the fuselage trim. The resin impregnated glass fibre support structure not only provides support for the insulation but a mounting for the furnishing sidewall and ceiling panels. This support structure generally consists of H-section channel members jointed to form an arch within the aircraft structure. It is attached to the floor beams and the stringers at various points, and its members are joined at the top of their arch on the centre line of the aircraft by attachment to spine members which are bracketed to the top most stringer. The member which abuts the near edge of the right-hand D.V. window when open has a hinged D.V. window recess sealing panel attached to it.
Flight Deck Flooring
The flight deck flooring is clad with a non-slip grey vinyl floor covering, with the exception of the raised insulated floor on which are situated the control columns and rudder pedestals, which are both themselves fitted with insulated covers. The vinyl is tailored to fit on assembly and the detachable panels are punched with holes to mate with the fasteners on the floor panels. Any loose edges of the vinyl panels are secured with tape No. 567 and Tretobond DR200 adhesive.
The insulated raised floor at the forward part of the flight compartment comprises of a centre section, left and right hand side sections, with foot ramps and wedges bolted to the centre section. The floor sections are fabricated with a double skin of impregnated glass fibre, containing a polyurethane foam insulating core; the foot ramps have metal treads and balsa wood cores. Insulated covers for the control columns and rudder pedestals are sealed to the insulated floor by rubber gaiters.
There are guard assemblies which are made from laminated glass cloth, which are designed to prevent debris and foreign objects sliding forward into the nose wheel steering linkage area, these are located on the flight deck floor forward of the captains and co-pilots rudder bars. Each guard assembly extends from the centre console to the side console closing panel. The guards are secured to the floor by utilising existing floor bolts and anchor nuts positions.
Ceiling and Sidewall Panels
These removable panels provide the interior furnishing trim for the flight deck, and also give access to the insulation blankets and fuselage structure. In addition to this they allow access to the aircrafts systems that are concealed behind the panels. The ceiling panels are of two types. One type which is situated between the equipment racks has a rigid impregnated glass fibre skin enclosing a polyurethane foam core. The other type, which is above the pilot’s stations, consists of a rigid impregnated glass fibre panel covered with a quilted vynide. The sidewall panels also consist of rigid impregnated glass fibre panels, which are fitted to the support structure, and include the blind boxes and sun visor stowage.
The window furnishings consists of impregnated glass fibre mouldings in the form of sills and fairings around the windshield, direct vision (D.V.) and side windows, and insulated covers over the D.V. and side windows. These mouldings are shaped to their associated windows, and comprise hollow glass fibre frames filled with rigid polyurethane foam. When the mouldings are fitted together with their insulated distance pieces and securing panels, they completely seal the window frames and surrounding areas with the exception of the air conditioning distribution outlets.
Side Consoles, Centre Console, Dashboard and Glareshield
The side consoles are each fitted to sidewalls of the flight compartment, immediately outboard of each pilot’s station, and they incorporate the instruments and control housings, along with compartments for the stowage of miscellaneous equipment. They consist of metal frames which are bolted to fixed brackets on the aircraft structure, and metal panels finished with grained vynide, which are secured to the frame and quick release fasteners.
The centre console, which houses the engine and flying controls, is situated between and forward of the pilot’s stations. The console consists of two main assemblies, a forward console supporting dashboard and glareshield, and a console set in a recess of the raised insulated floor which is made up of an insulated floor panel, a base structure and a hinged crate assembly with a guard rail on top. The side and rear insulated panels of the laminated glass fibre with polyurethane foam cores provide furnishing trim enclosing the two assemblies, giving the external appearance of one console.
The metal glareshield, finished in mat black and padded on the trailing edge with grained vynide covered foam padding, forms a continuation of the windshield furnishing trim, extending aft from the windshield to provide a canopy cover over the dashboard.
