EXAM 2025 QUESTIONS AND ANSWERS
Electromagnetic Interference (5.5.5.5) - ANS 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) - ANS Establishing a physical wire path that gives electricity a path to
earth/ground.
Bonding (5.5.5.5) - ANS Connection of non-current carrying conductive elements ie.
enclosures and structures.
Conductor plating (5.5.5.1) - ANS 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) - ANS 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 - ANS a. 1 volt

, Voltage rating (5.5.5.1) - ANS 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) - ANS 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) - ANS 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) - ANS A bundle of wires covered by rubber or plastic along which an electric
current can pass.
New Equipment Acceptance (5.4.1) - ANS Receiving inspection, physical condition, inventory
of equipment and accessories for installation
Visual inspections (5.4.1.2) - ANS 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) - ANS Red Tagged - Placed in quarantine - report using
FAA Form 8120-11. Ref. AC 21-29.
Direct Marking (5.5.5.3) 1 - ANS 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.
Indirect Marking (5.5.5.3) 2 - ANS Identification sleeves can be used if direct marking on the
wire is not possible. Indirectly-marked wire or cable should be identified with printed sleeves at
