FAA questions PP electrical FINAL (for the boys)
Answered Correctly!!
A certain direct current series motor mounted within an aircraft draws more
amperes during start than when it is running under its rated load. The most
logical conclusion that may be drawn is
The condition is normal for this type of motor.
When using akn electric starter motor, the current flow through it
is highest ar the start of motor rotation
Airflow to the pneumatic starter from a ground unit is normally prevented from
causing starter overspeed during engine start by.
Activation of a flyweight cutout switch.
Why is it unnecessary to flash the field of the exciter on a brushless alternator?
Permanent magnets are installed in the main field poles
1- Electrical circuit protection devices are rated based on the amount of current
that can be carried without overheating the wiring insulation.
2- A "trip-free" circuit breaker makes it impossible to manually hold the circuit
closed when excessive current is flowing. Regarding the above statements,
both No.1 and 2 are true
Alternators (AC generators) that are driven by a constant- speed drive (CSD)
mechanism are used to regulate the alternator to a constant
hertz output
1, Alternators are rated in volt-amps, which is a measure of the apparent power
being produces by the generator. 2, Alternating current has the advantage over
direct current in that its voltage and current can easily be stepped up or down.
Regarding the above statements,
both No.1 and 2 are true
1, Electrical wires larger than 10 gauge use uninsulated terminals. 2, Electrical
wires smaller than 10 gauge use uninsulated terminal Regarding the above
statements,
Only No. 1 is true
Why is a constant-speed drive used to control the speed of some aircraft engine-
driven generators?
So that the frequency of the alternating currennt output will remain constant
The Time/ current capacities of a circuit breaker or fuse must be
Below those of the associated conductor
In order to reduce the possibility of ground shoting the circuits when the
connectors are separated for maintenance, the AN and MS electrical connectors
should be installed with the
Pin section on the ground side of the electrical circuit
Starter brushes should be replaced when they are worn down to
one- half of the original length
electrical switch are rated according to the
voltage and the current they can control
