describe the shape of the fuselage
tubular with oval cross section
what are the 2 types of truss fuselage constructions
pratt truss, warren truss
what is a truss
construction of several members joined to form a rigid structure
what can truss fuselage constructions be made from
steel or sometimes wood/aluminium
whats the purpose of a stressed skin fuselage
the fuselages skin carries all the stresses
almost all pressurized aircraft have what type of construction
semi-monocoque
during the manufacturing process what is the aircraft fuselage assembled using
two part polysulfide sealant
what are the 2 typical methods of applying sealant to an aircrafts fuselage
faying seal, fillet seal
describe a faying seal
where two pieces of metal overlap
describe a fillet seal
two pieces of metal are joined together
what are electrical cables or control cables generally sealed with
rubber, silicone, sealant plates
what parts of the aircraft are attached to the fuselage
wings, stabilisers, engine pylons, landing gear
what are the stabilisers typically fitted using
bolt fittings to frame members of bulkhead
where are engine pylons attached
to the wing
on many aircraft what is the main landing gear attached to
the wings
whats the purpose of seat tracks
secure seats and ensure easy removal
what is used to move cargo in the cargo compartment
rollers, tracks, PDUs

anti-roll-out
what are the main entry doors functions
quick safe unloading/loading and emergency exits
what type of door are main entry doors
plug type
whats the function of service doors
access to systems on the aircraft
what type of door is a service door
non-plug type
whats the function of cargo doors
provide access to all cargo compartments
what type of door are cargo doors
non-plug type
describe a plug type door
self sealing and used on aircraft with cabin pressure
describe a non-plug door
opened inward apart from cargo doors
whats the function of door seals
pressurisation, light transmission, noise transmission, aerodynamics
what are the 4 common door seal shapes
bulb type, diaphragm, flap type, muiltiform
when must an aircraft have a flight deck door
passenger carrying aircraft with maximum 45,000kg take off mass or passenger seating greater than 60
what materials are used to make flight deck doors
glass polymers, kevlar, laminates
what must you always check before opening any door on an aircrfat
in safety and cabin pressure light is off
for hydraulically operated cargo doors whats used to prevent actuator movement during maintenance
safety gags
what colour will show if a door is not close
amber
what shows when a door is closed latched and locked
nothing
what does A mean on doors
auto, green
what does M mean on doors
manual, white
what are the 2 types of windows
passenger, flight deck
what type of window are passenger windows
fixed plug type
why do windows have two layers of acrylic
failsafe
how many flight deck windows are there on modern aircraft
6
whats the purpose of the flight deck sliding window
emergency escape
what are the 2 types of damage found on flight deck windows
delamination and bubbles, chicps/cracking/scratches
