The following is the equation for the above
Total number of strokes
5 (strokes per word)
- (errors x 50) = Gross words
5 (minutes of test)
= Words per minute.
The following example shows how this
formula works. Assume that you have just
completed the exercise in figure 2-8, view B.
Further, assume that you have completed the
entire exercise within the 5-minute time period
allowed. This gives a total of 630 strokes typed.
When checking over what has been typed, you
find 4 errors. Your words per minute are figured
Throughout the Navy, computers are being
used more and more to simplify the storage and
management of statistical data. The computer
uses modern technology to simplify the handling
of typed words and ideas. Computer power makes
typing faster, easier, and more efficient.
The computer will help you do your day-to-
day jobs quickly and easily. This system records
your typing; therefore, you only need to re-enter
changes and corrections. This is much better than
using whiteout for a minor error or retyping an
entire letter because you inadvertently left out a
sentence or paragraph.
The computer is designed to look and respond
like a typewriter. The things you will learn about
your computer will grow out of what you already
know about typing. You know how paper
advances through a typewriter; the screen on the
computer is your paper. The keyboard of the
computer is very similiar to that of a typewriter,
with the addition of special keys to operate
the various computer commands. Since many
commands have purchased their own computer
equipment, it is impossible to describe the
different makes and models in this TRAMAN.
Most manufacturers of computer equipment
include a self-paced, easy to understand instruc-
tion booklet or manual on their particular
computer. Take time to read the instructions
before attempting your first letter. In a short time,
you will be able to successfully operate your
computer and become familiar with the various
word processing programs available to you.
The AZ also uses calculating machines in
performing various tasks. They are especially
useful when preparing certain reports and in
logbook maintenance. There are many types of
calculating machines used in aircraft maintenance
activities; therefore, no standard instructions on
their operation are presented here.
The manufacturers manual for each machine
explains what it can do and how to operate it.
These manuals, with the help of experienced AZs
in your activity, should help you to develop
proficiency in operating these machines.
Some calculating machines furnish a printed
record (usually on tape) of each item added. This
printed record may be used to check possible
errors in copying numbers. Tapes should be
attached to reports when forwarded for signature.
This provides a simple method of checking the
accuracy of the report by the designated signer.
Some of the standard calculators used in the
Navy are the Marchant (SCM Corporation),
the Friden (Singer), and the Monroe (Litton
Industries). The same principles apply for
operating all rotary calculators, but the keyboard
arrangements and steps involved in operation vary
slightly, depending on the manufacturer and the
particular model. You will have to learn the details
about your machine from an experienced operator
and by studying the manufacturers instruction
Electronic Solid-State Calculator
The electronic calculator is a miniature
electronic computer. All major office machine
manufacturers now have models on the market.
Its operating keys are similar to those of rotary
calculators. However, it has additional keys for
mathematical signs and for the storage and recall
of numbers. Your computations and answers are
projected by a cathode ray onto a small, TV-like
screen located at the top of the machine. This
calculator has a number of advantages over rotary
calculators; it is easier to operate, quicker, quieter,
