Update to General Test June 2013General Test Guide 2013 ASA-AMG-13

With the following changes, ASA’s General Test Guide 2013 provides complete preparation for the FAA Aviation Maintenance Technician (AMT) General Knowledge Exam.

About the Test ChangesThe FAA exams are “closed tests” which means the exact database of questions is not available to the public. The question and answer choices in this book provide the largest sampling of representative FAA questions available and they are derived from history and experience with the AMT testing process. You might see similar although not exactly the same questions on your official FAA exam. Answer stems may be rearranged from the A, B, C order you see in this book. Therefore, be careful to fully understand the intent of each question and corresponding answer while studying, rather than memorize the A, B, C answer. You may be asked a question that has unfamiliar wording; studying and understanding the information in this book and the associated reference documents will give you the tools to answer all types of questions with confidence.

We invite your feedback. After you take your official FAA exam, let us know how you did. Were you prepared? Did the ASA products meet your needs and exceed your expectations? We want to continue to improve these products to ensure applicants are prepared, and become safe AMTs. Send feedback to: [email protected]

The next FAA test change is expected in October 2013.

Page Question Correct Number Number Answer Explanation

3 8002-1 [A] A new question is added to read:

8002-1. What is the opposition to the flow of AC produced by a magnetic field with generated back voltage (EMF) called?

A— Inductive reactance.B— Capacitive reactance.C— Mutual inductance.

Alternating current is in a constant state of change; the effects of the magnetic fields are a continuously inducted voltage opposition to the current in the circuit. This opposition is called inductive reactance, symbolized by XL, and is measured in ohms just as resistance is measured. Inductance is the property of a circuit to oppose any change in current and it is measured in henries. Inductive reactance is a measure of how much the countering EMF in the circuit will oppose current variations. (AMG102) — FAA-H-8083-30


8002-2. Electrostatic fields are also known as

A— Dielectric fields.B— Electrostatic fields.C— Static fields.

A field of force exists around a charged body. This is an electrostatic field (sometimes called a dielectric field) and it is represented by lines that extend in all directions from the charged body which terminate where there is an equal and opposite charge. (AMG031) — FAA-H-8083-30


8009-2. Convert farads to microfarads by

A— multiplying farads by 10 to the power of 6B— multiplying picofarads by 10 to the power of 6C— multiplying microfarads by 10 to the power of 6

Each farad is equal to 106 microfarads. Example: 2 farads is equal to 2 × 106 (2,000,000) microfarads.(AMG102) — AMT-G Ch 4

8009-3. Convert farads to picofarads by:

A— multiplying farads by 10 to the power of 12B— multiplying microfarads by 10 to the power of -12C— multiplying picofarads by 10 to the power of 12

Each farad is equal to 1012 picofarads. Example: 2 farads is equal to 2 × 1012 (2,000,000,000) picofarads.(AMG102) — AMT-G Ch 4

6 8020-1 [C] A new question is added to read:

8020-1. Which effect does not apply to the movement of electrons flowing in a conductor?

A— Magnetic energy.B— Thermal energy.C— Static energy.

Current flowing through a conductor produces a magnetic field and also dissipates thermal energy. (AMG031) — AMT-G Ch 4


8037-1. What is the basic unit of electrical quantity?

A— Electromotive Force.B— Ampere.C— Coulomb.

The coulomb is the basic unit of electrical quantity. 1 coulomb is equal to 6.28 X 1018 electrons. (AMG031) — AMT-G Ch 4


8045-1. In a parallel circuit with four 6-ohm resistors across a 24-volt battery, what is the total voltage across resistor-three (VR3) in the circuit?

A— 6 volts.B— 18 volts.C— 24 volts.

In a parallel circuit the source or battery voltage is applied to each of the individual resistors. (AMG102) — AMT-G Ch 4

13 8049-1 [B] A new question is added to read:

8049-1. In a parallel circuit with three 6-ohms resistors across a 12-volt battery, what is the total current (It) value in the circuit?

A— 2 amps.B— 6 amps.C— 12 amps.

The total resistance of this circuit is 2 ohms. The total current flowing in this circuit is 6 amps. (AMG102) — AMT-G Ch 4


8084-1. Which of the following logic gates will provide an active high out only when all inputs are different?

A— XNOR.B— NOR.C— XOR.

The output of the XOR (Exclusive OR) gate will only be at an active high when one and only one of the two inputs is high. If both inputs are low, or both inputs are high, then the output of the gate will be low. (AMG102) — AMT-G Ch 4



25 8091 [C] The explanation is changed to read:

Nickel-cadmium batteries can be charged rapidly by using a constant-current method (constant voltage and varying current). (AMG031) — AMT-G Ch 4


8120-1. (1) Sketches are usually made with the aid of drafting instruments.(2) Sketches are usually more complicated to make when using graph paper.Regarding the above statements,

A— Only No. 1 is true.B— Only No. 2 is true.C— Neither No. 1 nor No. 2 is true.

Sketches are simple drawings made without the use of tools. It is easier to do a sketch on graph paper where dimensions are easier to visualize without using tools such as a ruler. (AMG001) — AMT-G Ch 5


8121-1. What is used to indicate that a surface must be machine finished?

A— Tolerances.B— Leader lines.C— Finished marks.

By using finished marks a drawing identifies those surfaces that must be machine finished. (AMG014) — FAA-H-8083-30

B— Anytime a repair or alteration causes EWCG to fall within the CG range.


8209-1. When a Teflon hose has been in service for a time, what condition may have occurred and/or what precaution should be taken when it is temporarily removed from the aircraft?

A— The hose interior must be kept wet with the fluid carried to prevent embrittlement/deterioration.B— The hose may become stiff and brittle if not flexed or moved regularly.C— The hose may have developed a set, or have been manufactured with a pre-set shape, and must be

supported to maintain its shape.

Teflon hoses develops a permanent set after having been in use for an extended period of time or may have been manufactured with a permanent set for the particular function, thus is should be supported to maintain its shape and prevent inadvertent straightnening. (AMG037) — AMT-G Ch 9


8379-1. What is defined as a group of bits representing a complete piece of information?

A— Byte.B— Bit.C— Word.

A byte is composed of a group of 8 bits and represents a complete piece of information in a binary system. (AMG031) — AMT-G Ch 4




8379-2. Convert the binary number 1111 to decimal form.

A— 14.B— 15.C— 16.

The binary number 1111 is converted bit by bit into decimal: 1000 = 8; 0100 = 4; 0010 = 2; and 0001 = 1; thus the entire binary number equals 8 + 4 + 2 + 1 = 15 in its decimal form. (AMG031) — AMT-G Ch 2
