questions well answered to pass
Electromagnetic Interference (5.5.5.5) - correct answer ✔✔caused when electromagnetic fields
(radio waves) induce high-frequency voltages in a wire or component. (AC 43.13-1B 11-89)
Grounding (5.5.5.5) - correct answer ✔✔Establishing a physical wire path that gives electricity a
path to earth/ground.
Bonding (5.5.5.5) - correct answer ✔✔Connection of non-current carrying conductive elements
ie. enclosures and structures.
Conductor plating (5.5.5.1) - correct answer ✔✔Copper wire plated with Tin, Silver, or Nickel.
Tin is the most common. wire plating has a slower oxidation rate than bare copper.
Voltage drop in wires (5.5.5.1) - correct answer ✔✔Should not exceed 2% of the regulated
voltage when the generator is carrying rated current or the battery is being discharged at 5
minute rate.
The allowable voltage drop in a 28 volt continuous circuit is:
a. 1 volt
b. 2 volts
c. 5 volts
d. 4 volts - correct answer ✔✔a. 1 volt
, Voltage rating (5.5.5.1) - correct answer ✔✔The voltage rating of a cable is the highest voltage
that may be continuously applied to a completed cable construction in compliance with the
relevant cable standard or specification
Shielded wire (5.5.5.1) - correct answer ✔✔Electrical wire that is enclosed in a braided metal
jacket. Electromagnetic energy radiated from the wire is trapped by the braid and is carried to
ground.
Receiving Inspection (5.4.1.1) - correct answer ✔✔ensure that incoming parts are checked
against purchase orders, manufacturers specifications, drawings and dimensions and other
available documentation to CONFIRM AUTHENTICITY of the material. Conformance to
applicable technical standards will be verified. Incoming material must be separated from
previously inspected material
cable (5.5.5.1) - correct answer ✔✔A bundle of wires covered by rubber or plastic along which
an electric current can pass.
New Equipment Acceptance (5.4.1) - correct answer ✔✔Receiving inspection, physical
condition, inventory of equipment and accessories for installation
Visual inspections (5.4.1.2) - correct answer ✔✔New parts will be visually inspected to confirm
the PN and SN, the part markings, and general condition. All parts/components must be
accompanied by documents the CLEARY INDICATE APPROVED/ACCEPTABLE SOURCE.
Suspected Unapproved Parts (SUP) - correct answer ✔✔Red Tagged - Placed in quarantine -
report using FAA Form 8120-11. Ref. AC 21-29.
Direct Marking (5.5.5.3) 1 - correct answer ✔✔Several different methods can be used to mark
directly on the wire: hot stamp marking, ink jet printers, and laser jet printers. The hot stamp
method can damage the insulation of a newer type of wire that utilizes thin insulators.
