What are the advantages of Flexible and Easier to route through
cables over push-pull tubes? aircraft
structure and lighter
What is the purpose of control used to connect control levers in the
cables cockpit to
control surfaces
What are two materials cable can Stainless steel (corrosion-resistance) -
be made of and why? where
corrosion is a factor maritime aircraft
Carbon Steel (Galvanised) - where greater
resistance to fatigue is required and
cheaper
than stainless steel
What installations are non-flexible For installations where the cable does not
cables used in? pass
over any pulleys
(1x7/1x9 configuration)
,How are flexible cables (7x7) Each strand is formed into a spiral shape
formed and it's advantage? when
the cable is wound together so all strands
will
stay in their position
(adds flexibility and prevents unravelling
when
cut)
(7x7 config 1/16 + 3/32 sizes)
Why are extra-flexible cables Flexible due to 133 individual wires and
more flexible? method
of construction. (7 strands of 19 wires)
Most commonly used in cable sizes from
1/8
inch up
What does the last 4 digits mean First three digits represent lengths in
on cable identification (NAS inches
system)? Fourth digit represents length in unit of 1/8
inch
How would you identify the IAW applicable aircraft publication
percentage of allowable wear of 30%
outer wires before replacement
What is the purpose of Cable used to connect control cables to a
termination and end fittings? component or other cables
(fitting type depends on cable’s use and
strength requirements)
, What are three types of cable Swaging
terminations? Splicing
Nicopress sleeves
What are the most universally Clevis and Threaded terminal
used swaging terminals and where modern jet aircraft
are they commonly used?
Describe a Clevis type fitting U shaped metal fitting with holes so a
clevis pin
can be fitted.
shackle used to connect two members of a
mechanical system such as a cable to rod
Describe a threaded type fitting used where the cable is attached directly
to a
component
What type of repair has the edges Non-flush repairs (patching)
of the patch plate bevelled and
protruding style rivets that are
used to hold the repair in place?
Describe a fork-type fitting two prongs that fit over the mating prong of
an
eye type fitting/lever
(smaller than clevis)
Describe an eye type fitting single prong and is connected to a fork
type
fitting
