201. How does low observable (stealth) technology enhance the aircraft?
- A.
It makes the aircraft invisible to most radar sites.
- B.
It increases the lethality and survivability of this weapon system.
- C.
It increases the visibility of enemy defenses.
- D.
It makes the aircraft nearly invisible to enemy defenses and increases the lethality and survivability of this weapon system.
Correct Answer
D. It makes the aircraft nearly invisible to enemy defenses and increases the lethality and survivability of this weapon system.Explanation
Low observable (stealth) technology enhances the aircraft by making it nearly invisible to enemy defenses. This means that the aircraft is difficult to detect and track using radar, giving it a significant advantage in combat situations. Additionally, this technology increases the lethality and survivability of the weapon system, as it allows the aircraft to approach targets undetected and deliver its payload with minimal risk of being intercepted or shot down.Rate this question:

201. Does stealth make the aircraft invisible? Explain.
- A.
No. Stealth makes the aircraft radar evading, not invisible.
- B.
No. Stealth makes the aircraft radar jamming, not invisible.
- C.
Yes. Stealth make the aircraft invisible to most 2nd generation radar systems.
- D.
Yes. Stealth makes the aircraft invisible to all ground based radar systems.
Correct Answer
A. No. Stealth makes the aircraft radar evading, not invisible.Explanation
Stealth technology is designed to reduce the radar signature of an aircraft, making it difficult for radar systems to detect and track it. However, it does not make the aircraft completely invisible. Stealth technology achieves this by minimizing the reflection of radar waves and by using special materials and shapes that absorb or deflect radar signals away from the radar receiver. While it can significantly reduce the aircraft's radar cross-section, it does not render it completely invisible to radar systems.Rate this question:

201. Define supercruise.
- A.
Achieving supersonic flight without the use of afterburners.
- B.
Achieving trans-sonic flight without the use of afterburners.
- C.
Achieving supersonic flight with the use of afterburners.
- D.
Achieving trans-sonic flight with the use of afterburners.
Correct Answer
A. Achieving supersonic flight without the use of afterburners.Explanation
Supercruise refers to the ability of an aircraft to sustain supersonic flight without the need for afterburners. Afterburners are typically used to provide an extra boost of thrust for supersonic flight, but with supercruise, the aircraft can maintain supersonic speeds using only its regular engines. This allows for improved fuel efficiency and longer range compared to using afterburners.Rate this question:

206. Contrary to the F-16, how far should personnel remain away from a transmitting radar on the F-22 aircraft?
- A.
100 feet
- B.
200 feet
- C.
300 feet
- D.
400 feet
Correct Answer
C. 300 feetExplanation
Personnel should remain 300 feet away from a transmitting radar on the F-22 aircraft, in contrast to the F-16. This distance is necessary to ensure the safety of personnel as the radar emits electromagnetic radiation, which can be harmful if exposed to at close proximity. By maintaining a distance of 300 feet, the personnel can minimize their risk of potential health hazards associated with the radar's radiation.Rate this question:

206. How far should personnel remain away from the stoned energy exhaust when the engines are running.
- A.
4 feet
- B.
6 feet
- C.
8 feet
- D.
12 feet
Correct Answer
B. 6 feetExplanation
Personnel should remain at least 6 feet away from the stoned energy exhaust when the engines are running. This distance is necessary to ensure their safety and prevent any potential harm from the hot gases and debris that may be emitted from the exhaust. Being too close to the exhaust can pose a risk of burns, injuries, or even fatalities, so it is important to maintain a safe distance of 6 feet.Rate this question:

207. How much faster does a fiber optic cable transmit information over twisted pair or coaxial cable?
- A.
10 times faster
- B.
15 times faster
- C.
20 times faster
- D.
25 times faster
Correct Answer
B. 15 times fasterExplanation
A fiber optic cable transmits information 15 times faster than twisted pair or coaxial cable. This is because fiber optic cables use light signals to transmit data, while twisted pair and coaxial cables use electrical signals. Light signals can travel at a much higher speed than electrical signals, resulting in faster transmission of information.Rate this question:

207. How is the glass fiber bonded to the ferrule in fiber optic termini?
- A.
Epoxy
- B.
Tape
- C.
Glue
- D.
Shrink wrap
Correct Answer
A. EpoxyExplanation
The glass fiber is bonded to the ferrule in fiber optic termini using epoxy. Epoxy is a type of adhesive that is commonly used in fiber optic applications because it provides a strong and durable bond. It is able to bond the glass fiber securely to the ferrule, ensuring that it stays in place and maintains proper alignment. Epoxy is also resistant to temperature changes and can withstand the harsh conditions typically encountered in fiber optic systems. This makes it an ideal choice for bonding the glass fiber to the ferrule in fiber optic termini.Rate this question:

207. At a minimum, a fiberscope should have what minimum magnification factor?
- A.
100x
- B.
150x
- C.
200x
- D.
250x
Correct Answer
C. 200xExplanation
A fiberscope is a device used for visual inspection of small and difficult-to-reach areas. It consists of a flexible tube with an eyepiece and a lens at the tip. The magnification factor determines how much an object is enlarged when viewed through the fiberscope. A higher magnification factor allows for better visibility of details. Therefore, a minimum magnification factor of 200x ensures that the fiberscope provides sufficient magnification to effectively inspect objects and areas of interest.Rate this question:

207.Assume the subtraction method is being used. If the cable under test is reading -21.2 dB and the patch cable signal loss was -19.6 dB , what is the signal loss of the aircraft cable only?
- A.
-1.6 dB
- B.
-2.7 dB
- C.
-1.3 dB
- D.
-3.5 dB
Correct Answer
A. -1.6 dBExplanation
The signal loss of the aircraft cable can be calculated by subtracting the patch cable signal loss from the reading of the cable under test. In this case, the patch cable signal loss is -19.6 dB and the cable under test is reading -21.2 dB. Therefore, the signal loss of the aircraft cable only is -1.6 dB.Rate this question:

208. How many loops are there in the liquid cooling system?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
B. 2Explanation
The liquid cooling system has two loops. This means that there are two separate paths through which the liquid flows. Each loop has its own set of components, such as pumps, radiators, and tubing, to cool different parts of the system. Having two loops allows for more efficient cooling as it helps to distribute the heat evenly and prevent any overheating issues.Rate this question:
