Airplane spotting enthusiasts also do the following except
Correct Answer
D. Record information about aircraft speedÂ
Explanation
Airplane spotting enthusiasts record information about air traffic control, airports, and communication to enhance their knowledge and understanding of aviation. However, they do not typically record information about aircraft speed. This is because determining the speed of an aircraft requires advanced equipment and expertise that is not typically available to airplane spotters.

4.
The following are observed by airplane spotters except
Correct Answer
D. Number of men on board
Explanation
Airplane spotters observe various aspects of aircraft, such as the noise of the engine, the number of vapor trails, and the position of the wings relative to the fuselage. These observations can provide valuable information about the type of aircraft, its performance, and its characteristics. However, the number of men on board is not typically something that can be observed from the outside of the aircraft, making it an exception to the observations made by airplane spotters.
5.
Air spotters use which of these to track the movement of airplanes?
Correct Answer
A. ADS-B Decoders
Explanation
Air spotters use ADS-B decoders to track the movement of airplanes. ADS-B (Automatic Dependent Surveillance-Broadcast) is a technology that allows airplanes to transmit their position, altitude, and other data. ADS-B decoders receive these transmissions and decode the information, allowing air spotters to track the movement of airplanes in real-time. This technology is widely used in aviation for air traffic control and monitoring purposes.
6.
Which of the following is not associated with airplane spotting?
Correct Answer
D. Binoculars
Explanation
Binoculars are not typically associated with airplane spotting because they are used for magnifying distant objects, whereas airplane spotting involves identifying and observing aircraft in the sky. AirNav Systems RadarBox and Kinetic Avionic SBS Series are both radar systems used for tracking and monitoring aircraft, while Walkie Talkies can be used for communication between airplane spotters.
7.
Which of the following is not an airplane spotting website?
Correct Answer
C. FlightWatch
Explanation
FlightWatch is not an airplane spotting website. The other options, FlightAware, Flightradar24, and Airliner.net, are all well-known websites specifically designed for airplane spotting and tracking. However, FlightWatch is not a recognized platform for airplane enthusiasts to track flights or gather information about aircraft.
8.
The journal "The Airplane Spotter" was published in
Correct Answer
C. 1940
Explanation
The correct answer is 1940 because the journal "The Airplane Spotter" was published during that year.
9.
Airplane Spotters monitor the following class of airplanes except
Correct Answer
D. Unmanned airplanes
Explanation
Airplane spotters monitor various types of airplanes, including business jets, commercial airplanes, and military airplanes. However, they do not typically monitor unmanned airplanes. Unmanned airplanes, also known as drones, are usually operated remotely and do not have a pilot on board. Therefore, they are not typically included in the scope of monitoring for airplane spotters.
10.
Airplane spotters also observe the following on a moving aircraft except
Correct Answer
D. Military airplane camouflage
Explanation
Airplane spotters observe various features on a moving aircraft to identify and categorize them. These features include national insignia, squadron badge, and code letters, which help in identifying the country, unit, and specific aircraft. However, military airplane camouflage is not typically observed by airplane spotters as it is not a distinguishing feature used for identification purposes.
