NCATT AET Questions and Answers Already Passed
Question :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)
Question :Grounding (5.5.5.5)
CORRECT ANSWER :Establishing a physical wire path that
gives electricity a path to earth/ground.
Question :Bonding (5.5.5.5)
CORRECT ANSWER :Connection of non-current carrying
conductive elements ie. enclosures and structures.
Question :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.
Question :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.
Question :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
Question :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
Question :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.
Question :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
Question :cable (5.5.5.1)
CORRECT ANSWER :A bundle of wires covered by rubber
or plastic along which an electric current can pass.
Question :New Equipment Acceptance (5.4.1)
CORRECT ANSWER :Receiving inspection, physical
condition, inventory of equipment and accessories for installation
Question :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.
Question :Suspected Unapproved Parts (SUP)
CORRECT ANSWER :Red Tagged - Placed in quarantine -
report using FAA Form 8120-11. Ref. AC 21-29.
Question :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.
Question :Indirect Marking (5.5.5.3) 2
CORRECT ANSWER :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 each end and at intervals not longer than 6 feet. The individual
