AIRCRAFT ELECTRICAL SYSTEM Flashcards
What is a cause of generator brush arcing?
Low spring tension
How many cycles of ac voltage are produced in a six pole alternator of the
revolving field type for each revolution of the rotor?
Three
The type of electric wire terminals used for most aircraft applications, in
addition to providing good current carry-ing capabilities, are designed
primarily___________.
to prevent circuit failure due to terminal disconnection.
The commutator of a generator__________ .
changes alternating current produced in the armature into direct current
as it is taken from the armature.
An ammeter in a battery charging system is for the purpose
of indicating the
rate of current used to charge the battery.
Which of the following is not one of the purposes of interpoles in a generator?
Reduce arcing at the brushes.
What is the color and orientation of the position lights for navigation on civil
airplanes?
Left side - red, right side - green, rear aft - white
What does a rectifier do?
Changes alternating current into direct current.
When a diode is checked for an open circuit or a short circuit, it should be
disconnected from the circuit.
For general electrical use in aircraft, the acceptable method of attaching a
terminal to a wire is by…
crimping.
What is the minimum bend radius for an electrical wire bundle?
Ten times the outside diameter of the bundle.
When approved, splices may be used to repair manufac-tured harnesses or
installed wiring. The maximum number of splices permitted between any
two connectors is______ .
1
AN/MS electrical connectors are specifically designed to meet…
military specifications.
The most common method of attaching a pin or socket to
an individual wire in an MS electrical connector is by
crimping and soldering.
The voltage output of an alternator may be regulated by controlling the____ .
resistance in the rotor windings
