  • 1

    The most common method of attaching a pin or socket to an individual wire in an MS electrical connector is by

    crimping and soldering

  • 2

    Residual voltage is a result of magnetism in the

    field shoes

  • 3

    Which of the following copper electrical cable sizes should be selected to replace a No. 6 aluminum electrical cable?

    No. 6

  • 4

    What is normally used to bond noncontiguous stainless-steel aircraft components?

    Copper jumpers

  • 5

    Which motor would be most likely to have an armature brake?

    Landing light retraction motor

  • 6

    What is the principal advantage of the series-wound dc motor?

    High starting torque

  • 7

    What is a cause of generator brush arcing?

    Low spring tension

  • 8

    Major adjustments on equipment such as regulators, contactors, and inverters are best accompl outside the airplane on test benches with necessary instruments and equipment. Adjustment procedure should be as outlined by

    the equipment manufacturer

  • 9

    Grounding is electrically connecting a conductive object to the primary structure. One purpose of grounding is to

    prevent development of radio frequency potentials

  • 10

    The nominal rating of electrical switches refers to continuous

    current rating with the contacts closed

  • 11

    What is the minimum bend radius for an electrical wire bundle?

    Ten times the outside diameter of the bundle

  • 12

    How can it be determined if a transformer winding has some of its turns shorted together?

    The transformer will get hot in normal operation

  • 13

    Where electric cables must pass through holes in bulkheads, formers, ribs firewalls, etc. the wires should be protected from chafing by

    using a suitable gommet

  • 14

    What is required when operating two aircraft ac generators in parallel?

    Frequency and voltage must both be equal

  • 15

    What is the color and orientation of the position lights for navigation on civil airplanes?

    Left side - red, right side - green, rear aft - white

  • 16

    A battery-generator system provides direct current. On installations requiring alternating current from the battery-generator system, it is necessary to have

    an inverter

  • 17

    Which of the following must be accomplished when installing an anti-collision light?

    Install a switch independent of the position light switch

  • 18

    Electric circuits are protected from overheating by means of

    fuses

  • 19

    When handling a high voltage capacitor in an electrical circuit, be sure it

    is fully discharged before removing it from the circuit

  • 20

    If the reverse current cutout relay contact points fail to open after the generator output has dropped below battery potential, current will flow through the generator armature

    opposite the normal direction and through the shunt field in the normal direction

  • 21

    Which of the following factors must be taken into consideration when determining the wire size to use for an aircraft installation?

    Allowable power loss, Permissible voltage drop, Current carrying capability of the conductor, Type of load (continuous or intermittent)
