Which of these is the aircraft data recorder?
Correct Answer
D. Black box
Explanation
The correct answer is "Black box". The black box is the aircraft data recorder, which is a device used to record various parameters and data during flight, such as flight controls, engine performance, and communication. It is typically located in the tail section of the aircraft and is designed to withstand extreme conditions, such as crashes or fires, in order to preserve the data for investigation purposes.
2.
Which of these is a lightening detector?
Correct Answer
C. Stormscope
Explanation
A Stormscope is a lightning detector. It is a weather detection system that helps pilots detect and avoid thunderstorms by providing real-time information on lightning activity in the area. It uses radio frequency technology to detect and display the location and intensity of lightning strikes, enabling pilots to navigate around hazardous weather conditions. This helps ensure the safety of the aircraft and its passengers by minimizing the risk of lightning strikes and turbulence associated with thunderstorms.
3.
Which of these can best be used as eyes and ears of weapons systems?
Correct Answer
C. Aircraft
Explanation
Aircraft can best be used as eyes and ears of weapons systems because they have the capability to fly at high altitudes and cover large distances, allowing them to gather information and provide real-time surveillance. They can be equipped with advanced sensors, cameras, and communication systems to collect and transmit data, making them valuable assets for military operations. Additionally, aircraft can be manned or unmanned, providing flexibility in their deployment and reducing the risk to human operators.
4.
Which of these is used for communication in aircraft?
Correct Answer
B. Intercom
Explanation
Intercom is used for communication in aircraft. It allows pilots and crew members to communicate with each other within the aircraft, enabling efficient and clear communication during flight. Unlike radio signals, intercom provides a direct and private line of communication within the aircraft. Telephone and emails are not commonly used for communication in aircraft due to limitations in connectivity and practicality.
5.
When was the first hints of glass cockpits observed?
Correct Answer
C. 1971
Explanation
In 1971, the first hints of glass cockpits were observed. This suggests that advancements in cockpit technology, specifically the transition from traditional analog instruments to digital displays, began to emerge during this time. The use of glass cockpits revolutionized aviation by providing pilots with more accurate and comprehensive information, improving situational awareness, and enhancing safety.
6.
When was the first aircraft with glass cockpit produced?
Correct Answer
B. 1985
Explanation
In 1985, the first aircraft with a glass cockpit was produced. This advancement in aviation technology replaced traditional analog flight instruments with electronic displays, providing pilots with a more intuitive and efficient way to monitor and control the aircraft's systems. The introduction of the glass cockpit revolutionized the way pilots interacted with the aircraft, enhancing situational awareness and improving flight safety.
7.
When was investigations in aerospace engineering began?
Correct Answer
B. 1799
Explanation
The investigations in aerospace engineering began in 1799.
8.
Which of these was one of the tactical sensors?
Correct Answer
A. Airborne radar
Explanation
Airborne radar is one of the tactical sensors because it is a type of radar system that is mounted on an aircraft. It is used for detecting and tracking targets in the air, such as other aircraft or missiles. This type of radar is advantageous in tactical situations as it provides the ability to gather real-time information on enemy aircraft or threats, allowing for better situational awareness and decision-making.
9.
Which of these is not a form of radar built by aircraft engineers?
Correct Answer
C. Supersonic radar
Explanation
Supersonic radar is not a form of radar built by aircraft engineers. Supersonic refers to speeds greater than the speed of sound, and radar is not typically used at such high speeds. Radar systems are commonly used for various purposes by aircraft engineers, including airborne early warning, anti-submarine warfare, and weather radar.
10.
Which of these is an eletro-optic system built by aerospace engineers?
Correct Answer
C. Active infrared sensor
Explanation
An active infrared sensor is an electro-optic system built by aerospace engineers. It uses infrared light to detect and measure objects in its field of view. This sensor emits its own infrared radiation and then measures the reflection or absorption of that radiation to determine the presence or distance of an object. It is commonly used in aerospace applications for navigation, obstacle detection, and target tracking.
