The FAA
Aviation Mechanic - General
test bank contains questions pertaining to
Basic Electricity
. The following list contains only a relatively small percentage of the pertinent
questions. Our software, which you are free to download now at no cost, will
generally contain a much more complete set of questions associated with this
test bank. This list is intended only to familiarize you in a general way with
the questions of the
Aviation Mechanic - General
test bank.
Did you know? Despite their claims of completeness,
the FAA test banks provided by several other online test preparation sources
are woefully incomplete. Read more about the
situation here. Our GroundSchool FAA written test preparation software generally
contains a much more up to date and complete question set and in no way suffers
from such deficiencies. In fact, it's the best way to prepare for your FAA written
test, period.
That said, while the following questions are intended
as a general familiarization tool, this list may not be up-to-date nor accurate.
We do not update this website as often as we update our software, which will
contain at any moment all questions that we have for a given test / topic. Therefore,
if you need to actually study for your test, instead of using the list below,
we strongly, strongly encourage you to download our GroundSchool
Aviation Mechanic - General
written test prep software. Not only is it more complete and more up to date,
but it also includes answers and explanation and has many features to make your
study fast and efficient.
