Why is the integrity of the cargo-compartment liner sealing important to the effectiveness of the aircraft fire-protection system?, The sealing primarily prevents moisture from reaching insulation blankets during flight., The sealed liner helps make the cargo compartment sufficiently airtight for Class C fire suppression to operate effectively., The sealed liner allows cargo-compartment pressure to remain permanently higher than passenger-compartment pressure., Which statement most accurately describes the construction and installation of the cargo-compartment bulkhead liners?, They are glass-reinforced phenolic floor-type panels bonded directly to the aircraft structure., They are flexible fiberglass blankets retained only by hook-and-loop tape., They are fiberglass/aluminium honeycomb-core panel assemblies with aluminium frames, attached by fasteners with silicone rubber tape between the frames and the aircraft structure., What is the primary function of the plastic waffle mats installed between the insulation blankets and the lower-lobe structure?, They provide a drainage path so moisture can flow toward the bilge drain valves., They provide the primary fire barrier between the cargo compartment and aircraft skin., They prevent cargo loads from transferring directly into the insulation blankets., Why are holes provided in insulation blankets where they cover body-frame intercostal webs?, To allow attachment of cargo-net anchorplates directly through the insulation., To provide access for inspection of cargo-liner fasteners without removing the blankets., To align with openings in the intercostal webs and permit air circulation between the blanket and the sidewall liner., The forward cargo door cannot be unlatched because its internal handle mechanism is obstructed. Which alternate access method is specifically provided?, Remove the forward ceiling blowout panel from inside the passenger compartment., Use the approximately 20-inch by 20-inch access panel beneath the passenger-compartment floor near the tenth window cutout from the front., Enter through the aft cargo compartment and remove the forward bulkhead liner., A technician needs alternate access to the aft cargo compartment because the aft cargo door cannot be unlatched. Which provision is identified in the training material?, Use the aft ceiling blowout panel located near the eighth window cutout from the rear., Use the forward cargo access panel near the tenth window cutout from the front., Remove the cargo equalization valve from the aft bulkhead and enter through that opening., When two full-width cargo nets are installed, which loading restriction applies around the cargo-door area?, Cargo may be placed only forward of the cargo door., Cargo may be placed inboard of the cargo door provided it is below the door sill., Cargo may be carried forward and aft of the cargo door, but not inboard of the cargo door., What additional loading capability is provided when the centerline cargo net is installed between the two full-width cargo nets?, Cargo can be placed directly inboard of the cargo door without further restraint., Additional cargo can be loaded outboard of the centerline net between the two full-width nets., The full-width nets are no longer required because the centerline net takes all longitudinal loads., Why are the upper surfaces of the cargo-net anchorplates installed almost flush with the cargo-compartment panels?, To provide secure attachment points for cargo-net tiedowns while minimizing protrusion into the cargo-loading area., To allow the anchorplates to act as pressure-relief devices during rapid decompression., To allow the cargo nets to slide freely across the floor during loading., Which combination correctly describes the principal functions of the cargo-compartment lining and insulation?, The lining provides acoustic damping while the insulation provides structural reinforcement., The lining provides only cosmetic protection while the insulation supplies the compartment fire barrier., The lining provides a water-resistant fire barrier, while the insulation helps retain warmth in the cargo compartment during flight.
