(201) Which is not an Air Force inspection concept?
- A.
Phased.
- B.
Periodic.
- C.
Preflight.
- D.
Isochronal.
Correct Answer
C. Preflight.Explanation
The term "preflight" is not an Air Force inspection concept. Phased inspections refer to a series of inspections conducted at specific intervals. Periodic inspections are regular inspections conducted at predetermined intervals. Isochronal inspections are conducted at specific hour intervals or flight hours. However, "preflight" refers to the process of inspecting an aircraft before each flight to ensure its airworthiness and safety, rather than being a specific inspection concept.Rate this question:

(208) An example of an electrostatic discharge sensitivity device is a...
- A.
Metal-oxide semiconducting read-only memory circuit.
- B.
Programmable read-only memory circuit.
- C.
Resistor.
- D.
Diode.
Correct Answer
B. Programmable read-only memory circuit.Explanation
A programmable read-only memory (PROM) circuit is an example of an electrostatic discharge sensitivity device because it is highly sensitive to electrostatic discharge (ESD). ESD occurs when there is a sudden flow of electricity between two objects with different electrical potentials. PROM circuits are particularly vulnerable to ESD because they store data using electronic charges that can be easily disrupted or destroyed by the discharge. Therefore, proper ESD protection measures must be taken when handling PROM circuits to prevent damage.Rate this question:

(209) What is not a flight line precaution used to protect electrostatic discharge sensitive components?
- A.
Touching the line replaceable unit (LRU) case with your hands prior to removal from the aircraft.
- B.
Touching the ends of aircraft wiring to the LRU case prior to installation.
- C.
Covering LRU connector plugs.
- D.
Using protective tote boxes.
Correct Answer
D. Using protective tote boxes.Explanation
Using protective tote boxes is not a flight line precaution used to protect electrostatic discharge sensitive components. The other options mentioned in the question are all valid precautions. Touching the line replaceable unit (LRU) case with your hands prior to removal from the aircraft helps to discharge any static electricity that may have built up. Touching the ends of aircraft wiring to the LRU case prior to installation ensures that any static charge is transferred to the case instead of the sensitive components. Covering LRU connector plugs also helps to prevent static electricity buildup. However, using protective tote boxes does not directly address the issue of electrostatic discharge and is not a specific precaution for protecting sensitive components.Rate this question:

- B.
100 feet.
- C.
2,000 feet.
- D.
10,000 feet.
Correct Answer
C. 2,000 feet.Explanation
Time domain reflectometers (TDRs) are used to test the quality and integrity of cables. They work by sending a signal down the cable and measuring the time it takes for the signal to reflect back. The longer the cable, the longer it takes for the signal to return. TDRs are designed to accurately measure cables up to a certain length. In this case, the correct answer is 2,000 feet, indicating that TDRs can effectively test cables up to that length.Rate this question:

- A.
Crew chief hammer.
- B.
Soft-faced hammer.
- C.
Ball-peen hammer.
- D.
Sledge hammer.
Correct Answer
C. Ball-peen hammer.Explanation
Aircraft mechanics commonly use a ball-peen hammer because of its versatility and effectiveness in their work. The ball end of the hammer allows for precise and controlled striking, making it suitable for shaping and forming metal components. Additionally, the flat end of the hammer can be used for striking and driving tasks. The ball-peen hammer's design and weight make it ideal for aircraft maintenance as it can withstand heavy use without damaging delicate parts or surfaces.Rate this question:

(223) What tool measures the specific degree of tightness of nuts or bolts?
- A.
Stress kit.
- B.
Bolt meter.
- C.
Tensiometer.
- D.
Torque wrench.
Correct Answer
D. Torque wrench.Explanation
A torque wrench is a tool specifically designed to measure the specific degree of tightness of nuts or bolts. It applies a predetermined amount of torque to the fastener, allowing the user to tighten it to the required specifications. This ensures that the fastener is neither too loose nor too tight, preventing potential damage or failure. A stress kit, bolt meter, and tensiometer are not typically used for measuring the tightness of nuts or bolts, making them incorrect options.Rate this question:

(224) The amount of clamping force developed in a bolt is called...
- A.
Strength.
- B.
Tension.
- C.
Stress.
- D.
Force.
Correct Answer
B. Tension.Explanation
The amount of clamping force developed in a bolt is called tension. Tension refers to the stretching or elongation of a material caused by the application of opposing forces. In the case of a bolt, when it is tightened, it experiences a tensile force that creates tension. This tension helps to hold the bolt in place and prevents it from loosening or coming apart under load. Therefore, tension is the correct term to describe the clamping force developed in a bolt.Rate this question:

- A.
Camloc.
- B.
Style II.
- C.
Style I.
- D.
Dzus.
Correct Answer
D. Dzus.Explanation
Dzus fasteners are commonly used for securing components to a panel. They are a type of quick-release fastener that provides a secure and reliable connection. Dzus fasteners consist of a receptacle and a stud, which can be easily engaged and disengaged by sliding the stud into the receptacle and turning it. This allows for quick and easy installation and removal of components, making Dzus fasteners a popular choice in industries such as aviation and automotive where frequent access to components is required.Rate this question:

(225) Whick lock wire method is most appropriate for hard-to-reach or closely grouped parts?
- A.
Double-twist.
- B.
Single-twist.
- C.
Dual-pigtail.
- D.
Emergency.
Correct Answer
B. Single-twist.Explanation
The single-twist lock wire method is the most appropriate for hard-to-reach or closely grouped parts because it requires less space compared to other methods. In this method, the wire is twisted around the bolt or fastener in a single loop, providing secure locking without taking up much space. This makes it ideal for situations where there is limited access or when parts are closely positioned, allowing for effective lock wire installation even in tight spaces.Rate this question:
