rescue coordination center (RCC)- A search and
rescue (SAR) facility equipped and manned to
coordinate and control SAR operations in an area
designated by the SAR plan. The U.S. Coast Guard and
the U.S. Air Force have responsibility for the operation
of RCCs.
rescue co-ordination centre [ICAO] - A unit
responsible for promoting efficient organization of
search and rescue service and for co-ordinating the
conduct of search and rescue operations within a search
and rescue region.
reserve - To keep something back or set it apart for use
in an emergency or for a special purpose.
reservoir - A place where an extra supply of something
is kept, for example, a tank in which fluid is stored.
residual - The remainder or anything that is left over.
residual charge - The remaining electrical charge left
on capacitor plates after they have been discharged.
residual fuel or oil - The fuel or oil that is trapped in
the lines and, therefore, not usable. In weight and
balance computations, residual fuel and oil are
considered to be part of an aircraft's empty weight.
residual magnetic flux - The magnetism that remains in
the core of an electromagnet after the magnetizing
current no longer flows in the coil. Also referred to as
residual magnetism.
residual magnetism - The magnetism that remains in
the core of an electromagnet after the magnetizing
current no longer flows in the coil. Also referred to as
residual magnetic flux.
residual magnetism testing inspection - An inspection
for magnetism that might be left in a ferrous part
following magnetic particle inspection. The test is
conducted with a magnetic indicator that discloses any

resin starved - In composites, an area deficient in resin.
A resin-starved part will not exhibit the structural
strength that a part made with the proper amount of
resin.
resin system - In composites, a mixture of resin and
ingredients required for the intended processing
method and final product.
resin transfer molding (RTM) - In composites, a
manufacturing process in which the residcatalyst
mixture is pumped into a two-sided mold in which a
fabric reinforcement has been placed. The part is then
heated and cured.
resistance (R)- The opposition to the flow of electrons
offered by a device or material. Opposition by
resistance causes a loss of power.
resistance decade box - An electrical test device that
provides the capability to insert selected values of
resistance into a circuit.
resistance furnace - A high-temperature furnace heated
by passing current through various high resistance
materials.
resistance thermometer - A temperature-measuring
device based on the linear change-in resistance of a
material as temperature varies. This device is
connected to a Wheatstone bridge to determine
resistance and thus temperature.
resistance welding - The fusion of metals by clamping
them together and passing a high amperage electrical
current through the joint. The resulting heat melts the
metal and the pressure causes the two pieces to hse
together. Spot and seam welding are forms of electrical
resistance welding.
resistance wire - A wire made from a high resistance
material, used in wire-wound resistors and heating
elements.
