Questions With Correct Answers
Electromagnetic |Interference |(5.5.5.5) |- |VERIFIED |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) |- |VERIFIED |ANSWER✔✔-Establishing |a |physical |wire |path |that |gives |electricity |a |
path |to |earth/ground.
Bonding |(5.5.5.5) |- |VERIFIED |ANSWER✔✔-Connection |of |non-current |carrying |conductive |elements |ie.
|enclosures |and |structures.
Conductor |plating |(5.5.5.1) |- |VERIFIED |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) |- |VERIFIED |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 |- |VERIFIED |ANSWER✔✔-a. |1 |volt
Voltage |rating |(5.5.5.1) |- |VERIFIED |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) |- |VERIFIED |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) |- |VERIFIED |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) |- |VERIFIED |ANSWER✔✔-A |bundle |of |wires |covered |by |rubber |or |plastic |along |which |an
|electric |current |can |pass.
New |Equipment |Acceptance |(5.4.1) |- |VERIFIED |ANSWER✔✔-Receiving |inspection, |physical |condition, |
inventory |of |equipment |and |accessories |for |installation
Visual |inspections |(5.4.1.2) |- |VERIFIED |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) |- |VERIFIED |ANSWER✔✔-Red |Tagged |- |Placed |in |quarantine |- |
report |using |FAA |Form |8120-11. |Ref. |AC |21-29.
Direct |Marking |(5.5.5.3) |1 |- |VERIFIED |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.
Indirect |Marking |(5.5.5.3) |2 |- |VERIFIED |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 |wires |inside |a |cable |
should |be |identified |within |3 |inches |of |their |termination
Wire |Identification |(5.5.5.3) |- |VERIFIED |ANSWER✔✔-All |wire |used |on |aircraft |must |have |its |type |
identification |imprinted |along |its |length. |It |is |common |practice |to |follow |this |part |number |with |the |
five |digit/letter |Commercial |and |Government |Entity |(CAGE) |code |identifying |the |wire |manufacturer. |
You |can |identify |the |performance |capabilities |of |existing |installed |wire |you |need |to |replace, |and |
avoid |the |inadvertent |use |of |a |lower |performance |and |unsuitable |replacement |wire.
